Re: [HOT] Spam messages

[Kretzer]

Hi,

I totally agree that this should be changed. I like your solution #3 with the checkbox.

 

Blake, I can see your point about wanting to give positive feedback. But this feedback is way more likely to be annoying than uplifting. It's okay if you get it once, but nobody will feel positively rewarded when they get dozens of identical messages. I think feedback has to be specific to be useful.

And never ever should a bot pretend to be a person. Less so when the person in questions doesn't even know about it. This will only create confusion, anger and misunderstandings.

If anything I would prefer a message like " This is an automated message to let you know that @noobuser has validated your task".

 

And one more thing: Sometimes it would be useful to answer directly to an inbox message. but that does not seem possible, or did I miss something?

I also think automated messages (especially with this text) are no good. For me validating, I see three situations:
1) The work is bad or the tile is not fully mapped: --> I invalidate. I always invalidate with a comment and I think everybody does it like this (or maybe it is even a must?)
2) The work is perfect, I don't have to correct anything --> I validate, and sometimes I write a comment, sometimes not (if it was a lot of work I write something, if there was almost nothing to map I dont)
3) It is something in between. A few objects are not mapped or some overlapping / not squared buildings etc. --> I correct it and press validate. Again, I comment sometimes, but not everytime.

Especially for number 3, the work is neither perfect or "awesome". So if there is an automated message like the text John posted, I don't want it to be sent out because it would be wrong.

How to improve it? Possible solutions (not ranked):
1) Make comments compulsory (maybe provide some text for copy-paste or own templates?)
2) Provide a page for every user with information about my mapped tasks. How many have been validated, how many invalidated, how many not checked? I am definitely interested in that. And if you map a lot it is better to have an overview over your work on such a page than on dozens of mails.
3) Create a checkbox: "I want to be informed, when this task gets validated" and when you check it, you get an email, if not you don't. (One should be able to set the default setting of this checkbox individually)

And apart from this: In the TM2 comment box, when I pressed "@" all usernames of mappers of the locked tile were proposed. In TM3 this isnt. I hope this will be implemented again, it really speeds things up.

I do have a strong negative reaction to seeing the word awesome all over the place it might work in Chicago but it doesn't fit the culture of many people from other backgrounds.

 

I have removed my email address so I no longer get these unwanted messages in my email.

 

A lot of OSM mapping is done by a few mappers.  On a project I'm working on one mapper has mapped more than 120 tiles. Fine but with so many messages any feedback I might want to give them will get lost in the bulk of the messages.  The other objection to this is the time it takes to review and read the messages in Task Manager.  The more you map the more junk mail you get.

 

A very unhappy validator.

Hi John,
One of the main feedback items we got was that people received no
notifications of when their work was validated so that is why we
switched from sending a message to the users when their work was
validated instead of only when it was invalidated.

They are probably going to stay and as I said, improved so when people
do not want to receive them anymore they can opt out of validation
emails/messages specifically.

Typically spam is unsolicited emails, however, emails from the Tasking
Manager are fully opt-in. If you do not provide your email address,
you do not receive any emails. You can remove your email address at
anytime and you will no longer receive emails from the Tasking
Manager.

As I said, eventually you will be able to opt in and out of different
types of emails/messages so you could choose to not receive messages
or emails when your tasks get validated.

Cheers

Re: [HOT] Checking validation work in TM3

[Kretzer]

Plus one. 
I also think a link on the "latest activity" list would be very useful. 
(By the way, is there a reason why this tab is hidden in the map? That looks a 
little strange to me)

"Last active" would also help to figure out if a new user is still around and 
likely to get the feedback in useful time. I think that's what you'd asked for 
before, and I agree that would be helpful  

Today I got some kind feedback by a user who validated two tasks and encouraged 
me to keep mapping. This user joined OSM a day ago and has 6 tasks mapped and 4 
tasks validated ... :-)

I think the standard squares are fine. The residential areas are easy to find,

That sounds like a good idea.

Re: [HOT] #Map4Ebola DRC OpenStreetMap Response to 2017 Ebola outbreak : 23-May 2017 priority mapping work

[Kretzer]

This task is nearly finished in the meantime ... 

"Buildings only" is an ice and quick job. But I wonder if it is neccessary to 
make such tiny tiles. Sometimes each house gets its own tile like her in the 
eastern part: http://tasks.hotosm.org/project/3059#task/230
This makes it a bit boring to open every tile in JOSM. In ID the ronud boundary

[HOT] Chequerboard Pattern

Hi,
have you noticed how the use of the Task Manager sometimes produces nice 
patterns like here:  http://www.openstreetmap.org/#map=9/5.5244/25.1862 ?

You can see that at least some users are very diciplined in staying inside the

Re: [HOT] Fwd: Re: landuse=residential within landuse=residential

[Kretzer]

Hi, I was also bothered by the coexistence of very small and very large residential area in many loosely populated African areas. 

I agree that the tag seems to make most sense in densely built-up areas - to differentiate it from other uses of built-up land, not from open areas.  

 

But I'm not sure about "boundary" either. In Johns original example it was suggested to circle clusters of two or three buildings, and I'm not sure about the benefits of this. In these cases I think  mapping buildings alone would be sufficient. Or am I missing something? In most renderings you can see the residential areas in smaller scales as the buildings - so you could identify populated areas more easily. Is that a benfit? Or could that be solved by different rendering?

 

Surely population density could be accessed more accurately by numbers of buildings than by sizes of "blobs", which are outlines very inconsistently ?

Betreff: Re: [HOT] Fwd: Re: landuse=residential within landuse=residential




First, overlapping landuse areas (even different ones) should always be corrected. It brings problems with the map data, I have seen and corrected areas where the overlapping did hide ponds from the rendered map. The same overlapping area masks some of the problems but should be corrected as well - either by deleting of one of the areas or by merging both together.

The next question is the landuse size in the mapped area.

From the view of the mapper in Europe, the landuse=residential in HOT is problematic. The residential area should be only where the region is used above all for housing people. The HOT use is to mark areas where there are some houses, depending on the project instructions. This ends with a very problematic rendering of some areas. Visually, you get one big blob of something most people understand as a town, not the reality of fields and farms. The very loose residential areas shouldn’t be there at all, IMHO. Villages/towns boundaries have their own tag, boundary. Usually, this is paired with boundary=administrative which is mostly unusable for HOT distance mapping because the information isn't available to the mapper. But nothing speaks against own tag - see here.

IMHO, the ideal solution would be to change the HOT practice of mapping residential areas. Leave landuse=residential only to the areas, where the buildings are densely packed together (even in a village, where there is real street there might be a residential area) - keeping the common interpretation. Give the residential area a lower importance than it has now, and start using the boundary instead, for example boundary=residential to mark the areas with buildings. A later mapping on the ground or use of governmental data if available could then change this in real administrative areas marking the hamlets, villages, and towns where appropriate and leaving the residential boundaries to the rural farm areas.

Ideally, such change would be preceded by discussing on the HOT and tagging list and followed by updating the wiki definition of a boundary, and by updating the HOT materials for users. It would need a slight change in JOSM HOT presets and in the iD editor as well, probably. However, it shouldn’t be very difficult to do so.

I understand the residential areas are used for getting population density in the HOT projects. The use of both tags together would be a better choice, getting the information about sparsely and densely populated areas at the same time.

Nick & John,

Determining where to draw the edge of landuse=residential can be difficult.
Here in Ethiopia most of the population lives in a rural setting where they farm areas of 1 to 10 hectares in size.

There are places where people live in villages, but often dwellings are quite dispersed.

Re: [HOT] Mapping buildings

I didn't know about the JOSM shortcut. Thanks, that's  very useful!

Also Iove the idea of having a scaling tool in iD - would second that 
suggestion. 
On the other hand I don't have much practical use for the new mirroring tools. 
Maybe others have the same priorities?

Re: [HOT] Task Manager slowness

Then again, I would have thought that 15% of one task always equal 15%, no 
matter how big the tiles are ...  ;-)

Personally I quite like small tiles, if they open up quickly. But as John 
pointed out - waiting for those tiles to come up can take a lot of the 
available time.

Re: [HOT] Task Manager slowness

[Kretzer]

Yes, those Aweil projects with the large number of tiny, odd shaped areas are 
nearly unusable.
I guess that's the reason why #2419 for example is not geting on

Shame, it's quite frustrating ... and I'd love a little after-lunch mapping at

Re: [HOT] Validating and imagery offset

[Kretzer]

Well, as I said, in most of the tiles I checked, the mapping was surprisingly 
good. I only did a little cleanup in some tiles, and reminded one or two 
mappers of the squaring.
 
But in my example there were cleanly mapped buidlings aligned to the provided 
custom imagery, and a well mapped road aligned to the Bing image which was 
quite offset. So I was wondering if it's the right thing to do to move the road 
as all the other features are aligned to the custom image.
Also most of the other newly mapped structures in the task would be aligned to 
the custom imagery. So I guess it's better to keep those? 
But in the end everything should be in the "right" place, shouldn't it?

Betreff: Re: [HOT] Validating and imagery offset

This is my personal view after doing more than a fair amount of validation.
 
If you square the buildings you are making an approximation on what the 
original mapper mapped.  It doesn't look as pretty to leave it as it was but 
that is what I would do.  If mappers used the JOSM building tool to start with 
there wouldn't be the problem.  Garbage in garbage out I think is the technical 
computing term.  Politically you aren't supposed to delete the mapper's work 
realistically it can be faster to delete and remap using the JOSB building_tool 
plugin.  If you have the mappers for three hours I can get more buildings 
mapped with the tool than they can do in iD and its a lot more accurate, that 
includes the overhead for installing and configuring JOSM.
 
If the buildings are way out compared to Bing then you could select one 
displaced building and note the name.  Now search for all the buildings, within 
that search for the mapper.  Hopefully all their buildings will be displaced 
the same amount, move one building to alignment and the others will fall into 
place.  Again realistically if a building is six feet or a couple of meters out 
its findable so I don't even bother moving them these days.
 
Why even bother validating you may ask, well its the 10,000+ unlabeled ways in 
Africa, the 2,000+ highway=living_street in Nigeria the groups of buildings 
that should be tagged landuse=residential but are tagged building=house, the 
crossing highways, the highways that almost meet, the highway=motorway between 
two villages 200 meters apart these are the ones I try to catch.
 
Try to provide feedback, "added 97 buildings" if it nudges the mapper to do it 
right next time you've saved some poor validator a lot of work correcting but 
don't bother if it was mapped more than a month earlier.
 
I know I'm cynical.

[HOT] Image offset issue #1515

[Kretzer]

Hi,
I started some tracing in task #1515 (Mochendi, Botswana). I opened a tile 
(#30) with all roads and many buildings already in place, all somewhat offset 
from the Bing imagery. Between them they were very consistent, so I figured it 
would make more sense to align the image than move alle the existing features. 
This I did and traced the missing buildings to the realigned image.

Now this tile is pretty consistent in itself but not to the adjoining areas. So 
what next? 
Can someone check the georeferencing of the Bing image? Or should the whole 
content be moved to fit to the current imagery? I did not check the whole area, 
but many roads seem to be similarly offset and many buildings aligned to the 
current Bing imagery.

Thanks!

Re: [HOT] Nepal earthquake - Roads query

[Kretzer]

Hi Al,
do you still have that problem?

It's not quite clear to me - is that the iD editor you are using? That is, you 
clicked on start mapping and then on edit with iD editor? Usually you just 
see the black lines at the starting zoom level, and when you zoom in you can 
see the features in different colours. Maybe you zoomed in too much so that 
there was nothing in that area? (Sometimes that can happen really quickly when 
you use the mouse wheel for zooming). Have you tried to move the map around a 
bit, using the left mouse button?
 
Otherwise maybe the map data was just slow to load for some reason, I can't 
think of any other explanation.

Re: [HOT] chinese letters

Hi Henning,

Google translate is cool! (translate.google.com) You can make it automatically recognize the language and offer translations.

These characters abviously mean area (or space, clearing or vacancy) - I would guess its a newbies attempt to mark something.



To be honest, I have deleted a similar area. But do make sure its not something based on newer imagery, like a new IDP camp. Some people apperantly have deleted those, because they couldnt see anything in the older Bing imagery ...

Re: [HOT] newbie needs advice - connecting paths

[Kretzer]

Thank you, Blake!
In the meantime I had traced those paths, and did fill some gaps where they got 
through vegetation - in this case I felt confident to do that.  I didn't follow 
on, as I need to get back to may day's work ...

To me it looks as if all the aligned buildings to the west are right at the 
edge on top of the ridge and like ther is a quite steep face to the north 
(where the forest begins) Probably the CycleMap is not quite accurate there?

 Hi that is an excellent example.
 
 Between the buildings you are right I don't see a path and more over, we 
 don't really need a path between those two individual buildings if that 
 is what you were referencing.
 
 But I do see a path going off into the woods to the NNE that I would 
 map, even though the trees obscure parts of it, it looks pretty clear it 
 is a complete path going to other buildings NNE of there.
 
 And I see one going E, ESE that is more obvious.
 
 And one basically W-E along the base of the forested hills.
 
 Those are about the only 3 significant paths that I see that I would map 
 and I would probably map them as complete trails even though it is 
 across rough terrain where the path is difficult to see. It looks pretty 
 clear to me you can walk a path along the base of those hills to all the 
 buildings at the base.
 
 It does take some experience and local knowledge helps and by all means, 
 if you are in doubt, do not map something, better something gets not 
 mapped than you map something that does not exist.
 
 Thank you all for the discussion!
 
 cheers,
 Blake

  Maybe it's not the best one - it looks like you can easily walk from one 
  building to the other, but you can't really tell the altitude differences. 
  OpenCycleMaps knows that there are steep gradients nearby, but I don't 
  think it's accurate enough to use with certainty at that scale.

  Andre, I think the case Suzan describes is not a proper path being 
  invisible, rather that people just walk without paths, eg between several 
  houses. In this case it would be pointless to draw a fan of paths to each 
  house. I would rather end the path somewhere in the village.
 
 
  In general I agree, that it is better to have a connected network - that's 
  why I asked. Still I think there are limits to this. In the cases I am 
  thinking of it was not possible to judge from the imagery if it is 
  physicallv possible to walk between two visible paths (like paths on either 
  side of a steep ridge). I did not want to send anyone over a cliff just 
  because I filled in the blanks ... After all we should map what is on the 
  ground, not what we think should be there.
 
  And I don't think many people use routing with paths in this time and 
  space. They don't even do that in my part of the Alps where a dense and 
  well mapped networks of official hiking paths exists.

  I disagree. In a case like you mention - a path, then an open area, then a

  undermines the usability of the database.

Re: [HOT] newbie needs advice - connecting paths

[Kretzer]

Hi,

I was also wondering about the best approach to connecting paths.

On one hand all highways only make sense when they are connected, on the other it does not feel good to me to guess too freely where an invisible path might go. Particularly in steep terrain paths that are quite close horizontally really dont connect, as there can be a cliff or something in between. I often feel tempted to close a short gap blindly but did not as this can be really dangerous. Its probably better to leave it as patchwork and hope that the map will be improved later with better imagery or people with local knowledge.



In other situations it feels quite safe to fill in the blanks, like when a clearly visible road disappears into a small forest and the same type of road appears on the other side.



As to waterways and paths it often helps to follow them for a longer stretch and see where they go. This often gives you a better picture, if you see them run into a bigger river for example.







PS Id also prefer a more permanent place than IRC to get answers, so people can read them up later. Maybe a kind of forum would be useful to not clog up the mailing list?

Betreff:[HOT] newbie needs advice


Hi all,

I am a newbie coming up with a few questions, It would be great if someone with more knowledge could take the time to answer them. They dont have to be answered here and now or via mailinglist, I am also on IRC #hot as katjaulbert. I am mapping in task #1018.

1) Paths: I have come across some that are obviously connected but there are small areas where I cantt follow their course. Same with paths that lead into forests, where they disappear and reappear on the other side. Should I connect them? I dont think its useful to have tiny bits of paths in the map or paths that lead into nowhere.

2) I need advice to distinguish dried waterways from paths. Waterways seem to be much broader and uneven and often accompanied from paths.

3) Tags: I cantt find some tags that are advised in the task instruction, for example bridge=supension. Are there any presets I forgot to load?

4) Imagery: I use Bing and Mapbox, are there any more sources? Also, is there a way to digitally zoom Mapbox imagery? Sometimes its easier to spot things with Mapbox, especially paths, but it stops displaying at some point.

Thanks for taking time!

Re: [HOT] data alignment to satellite imagery

[Kretzer]

Hi Joshua,
if you do the fix alignment, you actually move the image, not the data. As 
far as I know usually Bing is used as the reference imagery, so I would not 
adjust that. If the other shapes are not aligned, the other people have 
probably used different imagery and not adjusted that.

Probably there are only some shapes in the wrong place, not all? Then you can 
adjust those manually or ignore them and ad your features with the default 
alignment.

Experts jump in please, if I am wrong here.

 Hi
 
 I'm new to HOT and I'm using the iD editor.
 I'm looking at an area that has shapes which do not align with the  
 Bing imagery.  Should I use the fix alignment tool before I add  
 additional data or just add the features as they appear with the  
 current alignment?
 
 Thanks

[HOT] Nepal: Hospital import gone wrong?

[Kretzer]

When looking at the Gorkha area in #1024 I noticed several nodes tagged as 
Hospital with a lot of information, quoting UNOCHA as source, but obviously 
in the wrong place, because there is nothing nearby. Like here: 
http://www.openstreetmap.org/edit#map=19/28.00839/84.62397
Looks like a mass import that somehow went wrong ... shame, because hospitals 
are important!


By the way, I am somewhat confused as to what is that called a task now? Is 
it a single tile (with a #) or is it the whole project?

Re: [HOT] Experienced mapper please verify: nonexistent stream on Task #1955, other mistakes

[Kretzer]

Hi Susan,
zooming out you can see that this is at the bottom of a quite large valley, so 
it is very likely that there is a stream, even if it isn't clearly visible. 
Maybe the person who drew it was using different imagery. I think it's not in 
the right place in the middle section (near the mapped path), but I would 
prolong it to the river in the east. it's not the most important feature at the 
moment, though.

What disturbs me more in the tile are the huge residential areas - those 
boundaries should be close to the buildings. They are also overlapping in one 
place, and there is an area within an area in the western part. Both shouldn't 
happen.

I'm just a semi-noob myself, but I am quite sure about these questions.

Re: [HOT] Experienced mapper please verify: nonexistent stream on Task #1955, other mistakes

[Kretzer]

Hi again, I just noticed Emmor beat me to the answer ... 
I wanted to ad that it can be useful to look at the history of changes in a 
case like this. Sometime I do this to make sure if the other person possibly 
had more recent information (or local knowledge, as there was a lot of mapping 
activity in Nepal in the last years - in some areas I have seen many edits by 
users with Nepalese sounding names). 

You can find the history if you change to the map view and click on the 
History tab on the top. In this case there were several very new users 
contributing.

As to the residential areas, I would draw the line around the larger clusters 
of buildings and leave the others outside. The instructions in this project 
specify that it should be around 20 or so buildings. Mappers' styles vary, 
personally I don't like the tiny residential areas. 
The important thing is that the buildings are there, so that rescuers can see 
were people are living.

Re: [HOT] Experienced mapper please verify: nonexistent stream on Task #1955, other mistakes

Thanks, Pierre!

In this case the buildings are all mapped individually, the question was just where to draw the line around them. I guess its not that important, as long as all the buildings are on the map.

so Ill better go back and do that ...

Dont forget that we work to locate people at risk after 8 days without any relief. People have lost everything under the houses ruins including food. It is important to report all the residential areas to assure to provide them relief.



We should remove the instructions 20 or so. Did not notice. This is valuable if you trace all buildings under clusters of 20. Isolated areas, even under 20 houses should be reported too.

Re: [HOT] limit validation to experienced users

[Kretzer]

Makes sense to me ...

In task #1018 there seems to be a user with little experience and lots of 
confidence invalidating dozens of tiles, arguing that every individual 
structure needs to be traced. 
The person even entered in a kind if edit war with maning. I really feel this 
is a waste of precious time. 

In this tasks there are very specific instructions on how to validate (which is 
a very good idea!). 
They do clearly say that the major highways need to be there, not all the 
highways. 

I guess the goal is to get the relevant structures as quickly as possible. That 
kind of nitpicking seems to be just slowing the job.

 Hi all,
 
 I wasn't able to read all the email I got for the last 3 days, and
 there's a ton of those.
 
 However, I've seen a lot of people complaining about beginner mappers
 validating tasks even if they're not experienced enough to do so.
 Before we find a way to avoid this with additions to the tasking
 manager, I think there may be a workaround.
 
 What about making the (100% done) projects in a private mode
 temporarily and give access to a limited list of users so that they
 can validate the done tasks.
 
 This could be used for this project for example:
 http://tasks.hotosm.org/project/1008
 
 This would prevent beginners to come to this project, wonder what to
 do and then validate tasks even if they don't know what they're doing.
 
 My 2 cents.

[HOT] Malawi Floods - residential areas vs. individual buildings

[Kretzer]

Hi,
while mapping some rural areas in the lake region, I was often debating with 
myself when it makes sense to draw a residential area - there are many 
buildings thinly spread over a wide area that seems to be used for agriculture. 
Like here: http://osm.org/go/lsN196yb--?layers=H
With myself I agreed on the rule that we would map a residential area, if there 
are more than two larger buildings close together, otherwise just map 
individual buildings. Does that make sense? I guess the advanteage of the areas 
is that they are visible at a smaller scale. On the other hand is seems silly 
to cover all the agricultaral land with residentisl tags.

By the way, wouldn't it be cool to have a place to ask such questions right in 
the Task Manager? Or at least have some FAQs there? I just noticed in another 
task - Mayendit, South Sudan, that is - that many people have the some 
questions about the conrete task. Like what are the round shapes here? - how 
can I tell the difference between a ditch and a path - how do we deal with 
different imagery from different seasons? - how do we tag the roads here?
This would certainly ad to the workload of the organizers, but I think it would 
be useful to achieve more conistent mapping.

Re: [HOT] #923 - Mayendit, South Sudan - highways to ditches?

[Kretzer]

Actually, I was considering mapping all the fences as well, because the patterns are really beautiful ...



Right now I took a brave (or stupid?) decision to change some long stretches from highway to waterway=ditch. One was even tagged as motorway_link .

With the imagery it is often quite hard to tell the difference bewteen paths or raods and ditches, but it seems to make more sense that there are many drainage ditches in those wetlands. And the end is a giveaway: roads normally dont end in rivers  http://www.openstreetmap.org/#map=16/8.1729/29.9339layers=H

I wasnt sure about the middle structure though, this could be path or ditch. maybe there are path running along such ditches.

What do you think? Or doesnt it matter at all, as no humanitarian units would need this information for finding the people? (At least it does make sense to remove the motorway, I guess ...)



Also I found this video that shows some of the area: https://www.youtube.com/watch?v=6jbDQNj6X_I - it does look quite wet there, but of course this will depend on the season.

1:00.

But the road I was changing into a ditch was in the north east, clearly not 
visible as a major road and running straight into the big river.
I think a lot of the area is flooded often, but have no local knowlegde 
whatsoever.

I wasnt sure about the middle structure though, this could be path or ditch. maybe there are path running along such ditches.
What do you think? Or doesnt it matter at all, as no humanitarian units would need this information for finding the people? (At least it does make sense to remove the motorway, I guess ...)

Also I found this video that shows some of the area: https://www.youtube.com/watch?v=6jbDQNj6X_I[https://www.youtube.com/watch?v=6jbDQNj6X_I] - it does look quite wet there, but of course this will depend on the season.

In South Sudan, actually it is generally fences and not walls. Check on these pics[https://www.google.com/search?q=mayenditclient=ubuntuhs=nHschannel=fssource=lnmstbm=ischsa=Xei=Bo75VN6AGoHnUPrRgZAHved=0CAkQ_AUoAw#channel=fstbs=itp:phototbm=ischq=village+south+sudan+trip]
The buildings and huts should be labelled building=yes.

Hi,

I cant even be sure there buildings are really used for permanent living, just

Im also curious what the many round strucures in the open area are. They could
well be man-made, maybe something like haystacks (or whatever material would be

Also I am unsure about the roads. There is one tagged as main road thats not

the other main road can clearly be seen as something like that), but didnt dare
to touch the top-level structures.
Thanks, and sorry again if I am asking in the wrong place!

Yes, I can see that. But would also map thin worm-shaped residential areas in 
such a case?

 Also, on the buildings. This is important as it gives the MSF
 
 epidemiologists a building count which then can be used for various
 
 analyses before the assessment team goes and used to cross-validate survey
 
 results when they are done.
 
 
 
 Thanks all for contributing!

Re: [HOT] Blog post on the mapping to support Support the Disaster Response in Malawi Flooding (Severin Menard)

[Kretzer]

Thanks, interesting post!

Will the mapping be evaluated by the local volunteers? I guess there is some 
cleaning needed, and a lot of decisions can't really be made from the aerial 
imagery. Like the classification of the roads, for example, or often you can't 
tell if something is really a building, or if its used for living (more so, 
where the imagery is not so clear).

I quite unsure how to handle the buildings that were tagged as nodes. Sometimes 
I could see to which buildings they belonged I included the node in the 
building outline, so that the tag information wasn't lost (I hope this the 
correct way of doing this ...). Often this is impossible, though, as there are 
lots of small buildings, often blurred, and lots of nodes. But if the outlines 
are added, many buildings would be counted twice. So is it best to do nothing 
where the survey was done on the ground and only ad buildings outside the 
tagged areas?
This is the first time I have done this, so maybe I'm overly confused ...

Also it would be very useful to see the date when the images were taken, so we 
could tell e.g. which is the newer iamge, where more than one is available. Is 
that technically possible? (the BING images say (C)2015, but I'm not sure that 
means the photos were actually taken in in 2015).
 
 

Hi,

With the Help of Charlotte, Cristiano and Blake, I published on the HOT
website this blog post presenting an overview of both the disaster and the
OSM mapping to support the response with pictures provided by the HOT
interns in Malawi There are two ongoing Tasking Manager jobs, one almost
done and the other one just starting. Please read, join and contribute!

[HOT] HOT 847 Malawi - small fields and dams

[Kretzer]

Hello again,

and sorry again, if Im asking in the wrong place (but I dont know any other ...).



While trying to do some lunchbreak-mapping, I came across a tile with lots of small fields with dams in between (at least thats what it looks like, I guess its rice??).

Someone started mapping all the dams as highway=footway, someone else started mappping some as highway=path.

Thats here: http://osm.org/go/lsJBMJclB--



I wonder if that makes sense, even if you can surely walk on them, but there a really lots ... Anyway, if so, I think path would be a better tag than footway, the latter is more of an urban feature, isnt it?



Thanks again and greetings from the Alps!

[HOT] Malawi Flood #847 - buildings among fields

[Kretzer]

Hi!
I have just been mapping some areas of the Malawi Flood task 847 and found many 
buildings or small groups of buildings among the fields. I wonder if these 
should be mapped as residential- of course I can't know if there rally are 
people living. Some might be used for storage or animals, but many look like 
they are inhabited. Like her for example: http://osm.org/go/lsDzzIwJm--
 
If I understand it correctly the ares for the task are the recently flooded 
ares intersected with the residential areas.
So the areas I am looking at here at are not part of the task, because they 
have not been marked as residential before. Does that mean they should not be 
mapped?
 
Sorry, if that's a stupid question - I'm quite new to this, but find it really 
interesting.
