[HOT] Governance WG 1st meeting this Wednesday August 13, 3pm (UTC)

[Jaakko Helleranta.com]

Hi all,

Let's have the first Governance Working Group meeting this upcoming Wednesday,
August 13 at 3pm UTC

(please note all people to whom daylight savings/summer time applies!) with
voice over Mumble and chat over IRC.

I'll be sending calendar invitations to those that have said that they are
participating or have signaled their interest.

If you are interested in the Governance WG please send me a note and I'll
add you to any possible communication that the WG might decide to have
outside of the general channels.

Any / all commentary regarding the idea to simply tackle the quorum problem
before diving into other changes in the bylaws / other governance issues is
most welcome and would be appreciated. All inputs gained will help in
figuring out / understanding how people at large feel about this issue
(that has been one of the obvious impediments for solid governance).

Thanks,
-Jaakko

Hi Blake,

Thanks for the report.
It looks like an issue on the server.
I'm afraid we won't be able to fix it before tomorrow unfortunately.

I hope we can fix it as soon as possible.
Sorry for the inconvenience.

[HOT] Can't edit any task from the task manager - "An error occured"

[Blake Girardot]

Hi,

The tasking Manager seems to think I have a task checked out, and the 
square for the last task I tried to checkout does show as being worked on.


When I click on the main project entry (Project 586) it automatically 
takes me to the task it thinks I am editing (task 290). It then says 
"Loading" and then blanks out the Contribute panel and returns a dialog 
that says "An error occured"


Trying to select another task in the same project results in the 
Contribute panel saying I already have a task locked. Clicking on the "a 
task locked" link or the "Select it again" button just results in the 
Contribute panel blanking and the "An error occured" dialog showing.


I have logged out and back in, let it sit for over 2 hours, cleared my 
cookies and browsing history, tried two different browsers, two 
different machines and operating systems, always the same behavior.


Any suggestions?

Best wishes,
Blake

I am very happy to be here and hope to share the message about HOT with 
a few local groups I am part of.



Looking at the edits for Naiyama, I see that they were done by a new
contributor using Potlatch 2. He does not provide information about the
Imagery he has used. So far he had less then 20 Edit sessions. He does
not seem to understand the basic rules of mapping.




JOSM is better to do such a Job. If we use the shorcut key Q, this let's
orthogonalize the buildings (right angles). A better and simpler way to
proceed, is to add the Building plugin in JOSM and trace using th B
shortcut Key.


Interesting, I think learning to use JOSM will be my next step.


Inside the landuse=residential polygon, wee see a second polygon with
the place=hamlet and name= tags. There is already a node to identify
this place and this polygon should be simply deleted since it does not
correspond to OSM mapping standards.

I also see some ways with the higway=footway tag. I cannot observe this
on the map and these ways are not connected to the highway network.

Since this is a small village and the work so badly traced, the best
solution to my point of view is to erase and restart.


I understand, very informative, thank you for explaining all of that. I 
will do as you and Ralf have suggested. As a new person I am very 
worried about making mistakes that is why I ask so many questions at the 
beginning.

Blake Girardot

Hi,

Thank you both very much for replying.

I am new to OSM and HOT so please forgive my ignorance.

It would seem that if I adjust the one section I am working on to align
the background with the previously mapped roads and buildings, it would
be throwing off the mapping in other sections on the larger map? Is that
correct? Is it a problem?

The section that raises this issue for me is this one:

http://www.openstreetmap.org/edit?editor=id&#map=15/8.2224/-11.2610


specifically the village area Naiyama.

If I understand your advice correctly, I would correct the background
image alignment to match the roads and some of the buildings and then
fix the rest of the buildings in the village.

Blake Girardot

We are happy that these Activations bring in new contributors. This is how I 
started myself with Haiti in 2010. More then having the satisfaction to help 
for humanitarian relief, this is a context where we have the opportunity to 
learn with the community that participate to this action.
Looking at the edits for Naiyama, I see that they were done by a new 
contributor using Potlatch 2. He does not provide information about the Imagery 
he has used. So far he had less then 20 Edit sessions. He does not seem to 
understand the basic rules of mapping. 


Looking at building outbounds, we cannot see a pattern that corresponds to what 
we see on the map.  The size of the buildings,  the direction of the walls do 
not correspond to what we see on the imagery. Potlatch 2 do not let 
orthogonalize the buildings. Tracing by hand, this contributor did not try to 
trace respecting the form of buildings.  


JOSM is better to do such a Job. If we use the shorcut key Q, this let's 
orthogonalize the buildings (right angles).  A better and simpler way to 
proceed, is to add the Building plugin in JOSM and trace using th B shortcut 
Key.

Since this is a small village and the work so badly traced, the best solution 
to my point of view is to erase and restart.

It would be good also that one of the validators contact him providing some 
instructions.

​Yes the buildings are pretty much nonsense, anyway, probably a much

was used previously. ​So, use the roads where correct (the 2nd southern
road is nonsense too), and do the villages accordingly. Remember to use
unclassified or path between villages, and tracks for roads to farmland.


Perfect. Thank you very much, just what I wanted to know!

[HOT] Project Malawi WK 2 updates

[maning sambale]

Hi,

We've posted an update of the second week of our project here in Malawi.

http://hot.openstreetmap.org/updates/2014-08-09_osm_workshops_for_project_malawi_week_2

We are preparing to leave to Blantyre for the series of training and
field mapping in the coming weeks.  We are looking forward to work
with the people who where with us last week to assist us in training
students and other government staff in Blantyre.

One thing that might help me (and perhaps others) when mapping those 
dense areas is a little on-the-ground background on how those cities are 
built. E.g the areas around



http://tasks.hotosm.org/project/611#task/710


or


http://tasks.hotosm.org/project/611#task/726


have blocks of houses several files deep. With my European background I 
have a hard time visualizing this area and deciding what is a separate 
building and what is just some roof-fixture.



Also, do you need every building separate or would outlines of complete 
block be enough?

Re: [HOT] Question about background image alignment

[Pierre Béland]

yes 


As I have explained before, you want to keep the general geometry of a village 
(distances, angles between the objects) to be the same.  Then if people have 
traced previously, you first move the image to align with what was there 
before.  


If this village have 30 meter offset with the rest of the world, this is less a 
problem then 30 meters between two buildings.

I can only tell from my perspective, I would look what's the offset of the 
majority of
objects in the tile and the surrounding tiles, and use that as your offset.

This presupposes that you use JOSM. With the browser it would be difficult.

A question would be then if you should correct the minority of misaligned 
objects. I don't know but I guess so.
