I've some experience in making GPS traces near high buildings, in Ottawa
the trace could be up to 30 meters out.  ie I walked a straight line but
the GPS trace was definitely not a straight line.

Hopefully it will work though.

Good point, John...

We are not looking for perfection at this stage, though. More something to
work from (i.e. anything we can work from!)

When used with the imagery it does helps confirm some roads.

Re: [HOT] Bangladesh track tracing (and chasing!)

I suggest all those that trace simultaneously, work from JOSM with the Geochat 
activated. Others will see you moving around. Simiarly, you will see others.

[HOT] Humanitarian Mapping for a class

2015-01-22 Thread Mueller, Thomas

Hello

Hello, I have been working slowly trying to integrate humanitarian mapping into 
my classes and students' education over the past couple of years .  I am a 
Geography professor, but I admit I am a jack of all trades master of none (as I 
teach crime mapping, demographic analysis, GIS, etc.)  I have tried several 
small projects- some successful and others not so successful.  This year in one 
of my upper level classes I have assigned a Humanitarian Mapping assignment.  
The students will be working on the Mapping Kamrangirchar (Dhaka, Bangladesh).  
I felt this was a good project for my students since there are quite a few 
structures that need to be mapped.I am requesting that my students spend 30 
minutes per week, every week mapping structures for this project.  Obviously 
this should not be a difficult for them, but I am hoping it will accomplish 
several objectives including:

1)  Help map the area

2)  Help the students understand how they can "donate" their time to help 
(within a topic in their field)

3)  Hopefully this will become part of their routine so they will continue, 
etc.

Also it will make sure that I donate my time too to this endeavor.

I have one question - how is the best way for me to check that they have 
completed this assignment every week?  Should I have them copy and paste their 
history on to a Word Document?  Is there a better way?

Hopefully if this project is successful, then I am hoping to integrate this 
assignment into more of my classes.

Thank you for your time

Re: [HOT] Humanitarian Mapping for a class

2015-01-22 Thread Rafael Avila Coya

Hi, Thomas:

I don't see a way to measure the time they are mapping. For example,
they can make changes to the map during 30 minutes or an hour but upload
them in only one changeset. Even if you ask them to upload every 5
minutes during 30 minutes, a lazy student could make just a house,
upload and go on listening music until next 5 minutes time.

I think the best you can do is to review the history of each user and
see how many objects each one has created, modified and deleted, and
that way have an estimation of how long they have been mapping.

Alternatively, you might consider changing time for objects, requesting
for example a minimum of new roads, buildings or whatever, instead of time.

Cheers,

Rafael.

Re: [HOT] Humanitarian Mapping for a class


Oh very cool!

Thank you very much for considering us for your class :)

I know people have really good suggestions for your question, but the 
main consideration for me is judging or grading or evaluating based on 
the quality of mapping, not quantity.


I just spent several hours last week cleaning up after (probable) 
students who were probably graded based on quantity so mapped a lot of 
non existent stuff.


So I would say emphasis on good mapping is the key to really helping the 
students and OSM and HOT as a whole. It probably wouldn't hurt to add a 
tag to their changeset comments like #gis101 so we know it is part of 
your project if we find anything that we might help provide feedback on.


And please keep in touch.

Thank you again!

Cheers,
Blake

Just as a heads up, we have a Missing Maps event happening in Berlin right
now where we're training a handful of new mappers. We're focused on tasks
844 and 845 which are both in Dhaka.

Re: [HOT] Humanitarian Mapping for a class

I wonder if a quieter HOT task might be easier?  Something like
http://tasks.hotosm.org/project/687 where it would be easier to spot the
work, possibly a tile or split tile per student and if you ask nicely some
one can validate it plus there aren't lots of other mappers swarming over
it.

Hi, Thomas:

I don't see a way to measure the time they are mapping. For example, they can 
make changes to the map during 30 minutes or an hour but upload them in only 
one changeset. Even if you ask them to upload every 5 minutes during 30 
minutes, a lazy student could make just a house, upload and go on listening 
music until next 5 minutes time.

I think the best you can do is to review the history of each user and see how 
many objects each one has created, modified and deleted, and that way have an 
estimation of how long they have been mapping.

Alternatively, you might consider changing time for objects, requesting for 
example a minimum of new roads, buildings or whatever, instead of time.

Cheers,

Rafael.

Re: [HOT] Humanitarian Mapping for a class

As Blake just said, it is important to also control the quality. JOSM should be
favored since there are various plugins like for buildings There is also a
Validation process when you upload the data. Osmose Map and other Validation
tools can also be part of the workflow to assure better quality. This can also
be querried by user. It is also important to look at the various
classifications like for road.

Below, I am looking more at how we can map efforts, have statistics and detail
of objects edited.

OSM keeps history of each object and user. There are various ways to query the
OSM database.
First, a summary of a student edit sessions (OSM Changesets) for the week can
be obtained with this simple
commandhttp://www.openstreetmap.org/api/0.6/changesets?bbox=left,bottom,right,top&time=datetime,datetime&user=uidxxx

left, bottom, right and top coordinates correspond to the coordinates showed on
OpenStreetMap.org when you click on the Export button.

examplehttp://www.openstreetmap.org/api/0.6/changesets?bbox=-79.013671875,44.071800467511565,-65.28076171875,50.597186230587035&time=2015-01-19T00:00:00Z,2015-01-20T00:00:00Z&user=226516

Detailed information about objects modified by the user over the week can be
obtained with an Overpass query. The Overpass UI site let do queries easily
and provides both a map and an OSM Changes file. The bottom of the map also
provides summary statistics about ojbects modified (ie. nodes, ways, relation,
POI's, polygons).

Try the script below, replacing uidxxx by a valid OSM UID. Note that Overpass
bbox is slightly different from the OSM API, the coordinates being in a
different order. Copy the API Overpass url link from the Export panel to have
these boudaries.
In the example below, replace the {{bbox}} parameter by these coordinates.
This will let you control wich area to query to extract data and compile
statistics.
You can also test the script as is with the {{bbox}} parameter and Overpass
will automatically calculate the coordinates. Zoom to the area you want to
investigate.

For a city, you should have no problem extracting the data but it could be for
a larger zone like a country.

For each student, it is then possible to have at the end of the week an image
of the map plus the OSM Changes file. The map would show the areas where he
concentrated his edits. The OSM Changes files would provide the detail about
the objects edited. Either the students do this individually, or a script is
written to do that automatically from a list of student UID's. The Map and
statistics would be both a way to control individual efforts and motivate the
students.

Overpass script , START and END dates, BBOX and UID parameters to be provided
[adiff:"2015-01-19T00:00:00Z","2015-01-21T00:00:00Z"];
(
node({{bbox}})(uid:"uidxxx");
way({{bbox}})(uid:"uidxxx");
rel({{bbox}})(uid:"uidxxx")
);
out meta;

Objet : [HOT] Humanitarian Mapping for a class

Hello Hello, I
have been working slowly trying to integrate humanitarian mapping into my
classes and students’ education over the past couple of years . I am a
Geography professor, but I admit I am a jack of all trades master of none (as I
teach crime mapping, demographic analysis, GIS, etc.) I have tried several
small projects– some successful and others not so successful. This year in one
of my upper level classes I have assigned a Humanitarian Mapping assignment.
The students will be working on the Mapping Kamrangirchar (Dhaka, Bangladesh).
I felt this was a good project for my students since there are quite a few
structures that need to be mapped. I am requesting that my students spend 30
minutes per week, every week mapping structures for this project. Obviously
this should not be a difficult for them, but I am hoping it will accomplish
several objectives including: 1) Help map the area 2) Help the students
understand how they can “donate” their time to help (within a topic in their
field) 3) Hopefully this will become part of their routine so they will
continue, etc. Also it will make sure that I donate my time too to this
endeavor. I have one question – how is the best way for me to check that
they have completed this assignment every week? Should I have them copy and
paste their history on to a Word Document? Is there a better way? Hopefully
if this project is successful, then I am hoping to integrate this assignment
into more of my classes. Thank you for your time Tom Mueller Thomas R.

I would recommend you start off with an assignment mapping their area - 
it's much easier to learn to map when you know what an area looks like 
from personal experience.


I have one question – how is the best way for me to check that they 
have completed this assignment every week?  Should I have them copy 
and paste their history on to a Word Document?  Is there a better way?
If you get their OSM username you can then view their contributions for 
the last week and check their changesets. Tools like achavi 
(http://nrenner.github.io/achavi/) can be used to visualize a changeset 
and hdyc (http://hdyc.neis-one.org/) can be used to look a users total 
contributions.

Hi Tom,
Glad to see you incorporating HOT into your geography classes. For
starters, I'd suggest you take a look at some of the material we've
compiled on the TeachOSM site[1] , which includes basic information on
creating a workflow, grading & rubric, as well as some case studies.
Secondly, I'd encourage you to subscribe to the TeachOSM mailing list[2]
and post your query there where other educators are likely to see it.
Lastly, you might talk to Nuala Cowen and Richard Hinton at George
Washington University. Nuala and Richard have incorporated digitizing
exercises for HOT in their classes and have a approach to making sure
students complete the tasks without resorting to minimum time.

Re: [HOT] Mapping Northern Nigeria ?

Hi Sergio
Priority of HOT is to make the Basemap and support the humanitarian 
organizations that operate in the various countries. We occasionnally did some 
Damage evaluation, but need more thought about the Tagging schema. 
While BaseMap is our priority, there might be some emergencies where we are 
asked to collaborate to Damage evaluation. For every of these events, we have 
to discuss among us and carefully evaluate if it pertinent to do so. 

 For our community to participate to damage evaluation in arm conflicts might 
be problematic both for the security of the humanitarians in the field and for 
our relations between the humanitarian organizations that operate in the field. 
These actions have to be evaluated very carefully..

Methodology is a distinct aspect and I will open a ticket to discuss about it. 
As it was discussed while we started the Haiyan Activation, we had to operate 
quickly in the emergency and established a temporary schema to be revised later.

[HOT] Damage evaluation tagging schema

>From the discusssion about mapping North of Nigeria, I open a distinct thread 
>about the Damage evaluation discussion about the more technical aspects 
>related to Damage evaluation and tagging schema.

This wiki page describes the schema used for the Haiyan 
typhoon.http://wiki.openstreetmap.org/wiki/Damaged_buildings_crisis_mapping

As we discussed at the beginning of the Haiyan activation, while establishing a 
temporary schema, this was be revised later to not affect tags such as building 
or highway.  Distinct tags should be added to reflect damages, road obstacles, 
debris or any other damage related objects. Any modifications will also have to 
be reflected in the humanitarian style to have the capacity to show damages on 
the map as we did for Haiyan.

While the BaseMap is our priority, there might be some emergencies where we are 
asked to collaborate to Damage evaluation. For each of these events, we have to 
discuss among us and carefully evaluate if it is pertinent to do so. 

Methodology is an other aspect. As it was discussed after Haiyan, there are 
limits to what can be done with Imagery. We cannot have the same classification 
/ hierarchy of damages from an aerial evaluation (often poor quality images in 
the context of climate related disasters) and field evaluation.
While we might decide to not do these evaluations, it is important to establish 
a good tagging schema and be ready for our next such action.
It dont think that this is a solution to have two attributes on the same key 
like building="commercial; damaged". It would be more difficult to query and 
this would breaks the rules for the map renderer styles. 
There are also discussions about adding permanently tags to the database and 
later not revising it.  More then a year after Haiyan, there are still a lot of 
damage related tags.  I have started to analyze how to revise this. But not yet 
processed.
There are various aspects to consider. 
- Use a map style to render damages (like the Humanitarian style for Haiyan)- 
Distinct methodology for aerial views or survey evaluations  ->  Specific role 
+ limits of aerial views vs structure damages- Evaluation vs Revision (either 
imagery or field survey)

The objects to evaluate can vary from one disaster to the other.  From the 
Haiyan experience, below I present proposals for tagging schema specific to an 
event. In this example, in the context of the Haiyan typhoon damages. Tnis same 
logic could be extended to  objects affected by other type of disasters.  

There are also various evaluation actions and status of actions  that sometimes 
need to be registered.- Type of action: aerial evaluation and revision, field 
evaluation and revision- Status of the revision : cloud coverage limited the 
evaluation.
The OSM key could be structured with various levels separated by semi-colons 
(ie damage:evaluation:building:haiyan).
If both evaluation and revision key where present, the style renderer rules 
could give a priority of revision over evaluation tags.

Excellent Thoughts. Interestingly, I am working on a 3D rendering of
buildings project now, and was planning on extending this to HOT's work
when done with the commercial project.

Having everything in one tag "k=" as you propose helps the query and
rendering scenario a lot. The only downside from a database perspective
would be if you ever needed to query for data within the key data itself.
This would be very slow.

For Example:  if someone wanted to display all Haiyan related data the
query would be something like *WHERE k is Not Null and lower(k) LIKE
"haiyan%"* which would trigger a sequential Pattern Match Scan. *k* would
need to be indexed, which would help somewhat.

One option would be to consider a couple of specific tags to help any
searches on columns that can be indexed, like

*hot:damage*=type of damage string (as per your proposal)
*hot:crisis*=Haiyan

This would allow rapid extraction of all Haiyan related data using indexes
with a query like *WHERE hot:damage is not null and
lower(hot:crisis)="haiyan";*

Also, consider adding "hot:" to the tag as this makes it very clear where
the data source is.

Just some thoughts for you to consider


Also, Do you have a summary of what tagging schemes were actually used
during Haiyan, I seem to recall building=damaged, or building=yes, damage=*

Hi Pierre:

I like this schema. Only two questions:

What do you mean with evaluation and revision?
Why not the event in 3rd and type of object at the end?

Re: [HOT] Mapping Northern Nigeria ?

2015-01-22 Thread S Volk

Hi Pierre, I definetly agree that it needs to evaluate if it's pertinent and 
the security to map damages. So I was focusing on basic mapping (residential 
and ways) in the time I have available. Also many refugees may have fleed to 
around. All that region around still needs basic mapping, many, many human 
settlements and their accesses in the images. Thanks, Regards, Sérgio

Subject: Re: [HOT]  Mapping Northern Nigeria ?

Hi Sergio
Priority
 of HOT is to make the Basemap and support the humanitarian 
organizations that operate in the various countries. We occasionnally 
did some Damage evaluation, but need more thought about the Tagging 
schema. 
While
 BaseMap is our priority, there might be some emergencies where we are 
asked to collaborate to Damage evaluation. For every of these events, we
 have to discuss among us and carefully evaluate if it pertinent to do 
so. 

 For our community to participate to damage evaluation in arm conflicts 
might be problematic both for the security of the humanitarians in the 
field and for our relations between the humanitarian organizations that 
operate in the field. These actions have to be evaluated very carefully..
Methodology is a distinct aspect and I will open a ticket to discuss about it. 
As it was discussed while we started the Haiyan Activation, 
we had to operate quickly in the emergency and established a temporary schema 
to be revised later.

This wiki page describes the schema used for the Haiyan 
typhoon.http://wiki.openstreetmap.org/wiki/Damaged_buildings_crisis_mapping

As we discussed at the beginning of the Haiyan activation, while establishing a 
temporary schema, this was be revised later to not affect tags such as building 
or highway.  Distinct tags should be added to reflect damages, road obstacles, 
debris or any other damage related objects. Any modifications will also have to 
be reflected in the humanitarian style to have the capacity to show damages on 
the map as we did for Haiyan.

While the BaseMap is our priority, there might be some emergencies where we are 
asked to collaborate to Damage evaluation. For each of these events, we have to 
discuss among us and carefully evaluate if it is pertinent to do so. 

Methodology is an other aspect. As it was discussed after Haiyan, there are 
limits to what can be done with Imagery. We cannot have the same classification 
/ hierarchy of damages from an aerial evaluation (often poor quality images in 
the context of climate related disasters) and field evaluation.
While we might decide to not do these evaluations, it is important to establish 
a good tagging schema and be ready for our next such action.
It dont think that this is a solution to have two attributes on the same key 
like building="commercial; damaged". It would be more difficult to query and 
this would breaks the rules for the map renderer styles. 
There are also discussions about adding permanently tags to the database and 
later not revising it.  More then a year after Haiyan, there are still a lot of 
damage related tags.  I have started to analyze how to revise this. But not yet 
processed.
There are various aspects to consider. 
- Use a map style to render damages (like the Humanitarian style for Haiyan)- 
Distinct methodology for aerial views or survey evaluations  ->  Specific role 
+ limits of aerial views vs structure damages- Evaluation vs Revision (either 
imagery or field survey)

The objects to evaluate can vary from one disaster to the other.  From the 
Haiyan experience, below I present proposals for tagging schema spe

Re: [HOT] Damage evaluation tagging schema

Hi Rafael,
There can be more then one step of evaluation and this both for evaluations 
based on imagery or field survey. 

For Haiyan we did1. Aerial imagery evaluation2. Aerial imagery revision (later 
revising objects already evaluated)3. Red Cross did some Field survey 
evaluations.

About the order of elements, I thought that this order would faciliate queries. 
For exampleselect key=damage:evaluation:select key=damage:evaluation:barrier:
Overpass Regex query can be used except I think adding a negation. 
see 
http://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL#Key.2Fvalue_matches_regular_expression_.28.7E.22key_regex.22.7E.22value_regex.22.29

Would it be efficient to make efficient Regex queries with postgresql? Then,  I 
think that the order of the elements would be less a problem.

Re: [HOT] Damage evaluation tagging schema

Hi Pierre, you should be asleep by now :) Hope the Snow is not too deep
either :)

I did not know about that the HOT Private Store. Is that rendered on the
OSm Layer or otherwise available? Would be interested in knowing a little
bit more about that.

Selecting objects in Sql is very dependent on the indexing. using + or <>
with an index is very efficient. Using Like "haiyan%" can be reasonably
fast if the data in the tag starts with the term you are searching for (eg:
"haiyan") (case conversion will have an impact depending on the size of the
string).

If your search term is in the middle of the key data, eg; "damaged: haiyan:
debris" it will be VERY slow as that will trigger a sequential scan

I have my own planetosm database, if the crisis is not a seperate tag, ie,
embedded within one tags data, I would set a trigger on the update that
extracted the crisis name, eg: haiyan, and stored it in an indexable
column. This is not particularly efficient, but I would have no choice as I
think it is very important to be able to extract data specific to a Crisis.

If you think about Overpass Queries, they would also not handle the data
embedded in the tag particularly well, I am sure they could do it, but it
would be subject to the same issue above.

One possible solution would be to use the Postgres HStore, which is
basically a text field. Postgres does have a unique ability to index data
withing the hstore, but I would not use this method on my production
database.

Osm does have these tags already defined, I am sure you are aware

   - building:condition
   =* *for the
   condition of the building*
   - ruins =* - *for ruins of
   buildings*
   - abandoned =* - *for
   a building *

My thought would to NOT use these, as the fact that a building was tagged
as abandoned is relevant in assessing if you want to assess it in a
Humanitarian Crisis.

Re: [HOT] Damage evaluation tagging schema

Hi Pierre

An additional thought, the context of teh mapping activity is an important
piece of information to everyone using OSM now and for the future

If you add a tag like (tag name is just for example)

context = "HOT"
context:crisis = "haiyan"
context:crisis:detail = "destroyed: etc ..."

would result in three searchable and indexable database columns that would
allow all HOT activities to be easily identified and statistical analysis
done, and be able to pull all HOT related activities for a specific crisis

It would be very obvious where the data originated and under what basis the
data was entered into the database. That data should stay permanently as it
would be relevant to future mappers to assess that object, but would also
keep the information relevant to Hot outside the mainstream OSM activity.

It also allows you to tag existing structures without affecting any of the
mainstream OSM rendering.

Cheers
MArk

Re: [HOT] Humanitarian Mapping for a class - thank you to everyone

2015-01-22 Thread Mueller, Thomas

Thank you to everyone.  These are all great comments and suggestions.  I am 
going to go through each email and build my worksheet.  I promise to share my 
work with the community.

Thanks

Hi Tom,
Glad to see you incorporating HOT into your geography classes. For starters, 
I'd suggest you take a look at some of the material we've compiled on the 
TeachOSM site[1] , which includes basic information on creating a workflow, 
grading & rubric, as well as some case studies. Secondly, I'd encourage you to 
subscribe to the TeachOSM mailing list[2] and post your query there where other 
educators are likely to see it. Lastly, you might talk to Nuala Cowen and 
Richard Hinton at George Washington University. Nuala and Richard have 
incorporated digitizing exercises for HOT in their classes and have a approach 
to making sure students complete the tasks without resorting to minimum time.

HTH,
SEJ

Hello

Hello, I have been working slowly trying to integrate humanitarian mapping into 
my classes and students’ education over the past couple of years .  I am a 
Geography professor, but I admit I am a jack of all trades master of none (as I 
teach crime mapping, demographic analysis, GIS, etc.)  I have tried several 
small projects– some successful and others not so successful.  This year in one 
of my upper level classes I have assigned a Humanitarian Mapping assignment.  
The students will be working on the Mapping Kamrangirchar (Dhaka, Bangladesh).  
I felt this was a good project for my students since there are quite a few 
structures that need to be mapped.I am requesting that my students spend 30 
minutes per week, every week mapping structures for this project.  Obviously 
this should not be a difficult for them, but I am hoping it will accomplish 
several objectives including:

1)  Help map the area

2)  Help the students understand how they can “donate” their time to help 
(within a topic in their field)

3)  Hopefully this will become part of their routine so they will continue, 
etc.

Also it will make sure that I donate my time too to this endeavor.

I have one question – how is the best way for me to check that they have 
completed this assignment every week?  Should I have them copy and paste their 
history on to a Word Document?  Is there a better way?

Hopefully if this project is successful, then I am hoping to integrate this 
assignment into more of my classes.

Thank you for your time

Re: [HOT] Damage evaluation tagging schema

Hi Pierre

Postgres Pattern Matching IS basically the same as Regex

http://www.postgresql.org/docs/9.0/static/functions-matching.html

It is more efficient to have the string you are searching for at the
beginning as an index can be utilized, but searching in the middle of a
string will trigger a sequential scan.

Some kind of Lucerne Indexing may offer an option, but I have never worked
with that on Postgres.

Cheers

Mark

Re: [HOT] Damage evaluation tagging schema

Hi Pierre

Actually, another issue needs to be addressed as well, what if an area
experiences two (or more) disasters, Ruby could well of passed over
Tacloban, now we would have two sets of data to manage. I recall you doing
something about that during the Ruby Activation.

Is it relevant that a building was subjected to damage from two events?

I guess the question is, how long should crisis related data persist and
what data should persist.

For example, if a building was initially mapped as a result of a HOT
activation, is that relevant information for future mappers? Historically,
is it relevant to know it entered the OSM database as a result of that
effort?

On possibility is to use the data for later assessment on the
rehabilitation work that was done??

Just some idle thoughts

Re: [HOT] Damage evaluation tagging schema

2015-01-22 Thread Kate Chapman

Hi Mark,

The HOT Private Datastore is specifically for private data, so what data is
available is up to the communities that have collected it. It is not really
in use right now though. By default it does use hot: as the prefix in a
JOSM preset to determine the data is uploaded, but this is a configurable
setting in the system. For any data to be uploaded to the Datastore instead
of to OSM the person has to be using JOSM and has to have the appropriate
plugin installed/enabled.

Best,

I did not know about that the HOT Private Store. Is that rendered on
the OSm Layer or otherwise available? Would be interested in knowing
a little bit more about that.

Selecting objects in Sql is very dependent on the indexing. using +
or <> with an index is very efficient. Using Like "haiyan%" can be
reasonably fast if the data in the tag starts with the term you are
searching for (eg: "haiyan") (case conversion will have an impact
depending on the size of the string).

If your search term is in the middle of the key data, eg; "damaged:
haiyan: debris" it will be VERY slow as that will trigger a
sequential scan

I have my own planetosm database, if the crisis is not a seperate
tag, ie, embedded within one tags data, I would set a trigger on the
update that extracted the crisis name, eg: haiyan, and stored it in
an indexable column. This is not particularly efficient, but I would
have no choice as I think it is very important to be able to extract
data specific to a Crisis.

If you think about Overpass Queries, they would also not handle the
data embedded in the tag particularly well, I am sure they could do
it, but it would be subject to the same issue above.

One possible solution would be to use the Postgres HStore, which is
basically a text field. Postgres does have a unique ability to index
data withing the hstore, but I would not use this method on my
production database.

Osm does have these tags already defined, I am sure you are aware

* building:condition
=*
/for the condition of the building/
* ruins =* - /for
ruins of buildings/
* abandoned =* -
/for a building /

My thought would to NOT use these, as the fact that a building was
tagged as abandoned is relevant in assessing if you want to assess
it in a Humanitarian Crisis.
