[HOT] Admin Boundary Extraction Service

[Samuel Aiyeoribe]

Hello HOTties,
Please does anyone know of a service for extracting/downloading OSM Admin 
Boundary that one can fork and host myself and also available on github.
Looking forward to your reply.

Re: [HOT] OSM Damage Assessment

[Pierre Béland]

Hi Michal,
HOT did not make Building damage assessments for Nepal, letting other groups 
outside OpenStreetMap taking care of this, and avoiding duplication of efforts. 
Coordination among various groups should be an important aspect of such 
assessments to progress rapidly and efficiently. We also have to clarify the 
objectives of Damage asssessments from aerial imagery. There are texts that 
describe objective of assessment from imagery vs from field data collection. 
Assessments from imagery is more to identify priority zones then individual 
buildings. Field data collection let's identify precisely the damaged buildings 
and the type of damage. 

For the OSM Response, we identified IDP camps in Kathmandu (Informal tent 
camps).  This task went well and was done rapidly. 

A second task was to identify potential helicopter landing zones.
The third task was about outlining villages in remote mountainous areas where 
severe damages could be identified. Contributors had more difficulty with this 
task and it progressed slowly, was never totally completed.
Questions1. No since not the same type of tasks2/4. links to all images used 
are in the Task Manager Instructions

Dear HOT community,
it has been a long time since I have written the first email which started this 
thread, but as I have been extremely busy over last period of couple of months, 
I am just starting now to dig into this again. And I would like to ask for your 
help, if you do not mind. 
So a small recap - I am planning on conducting a research on the quality 
assessment of the different damage assessments that were undertaken for the 
Nepal earthquake. Concretely, I would like to focus on conducting a validation 
studies on how crowdsourcing tools/organizations/campaigns, such as Tomnod and 
HOT are "good enough" in producing damage assessment. On the other side, I have 
the data coming from UNOSAT/Copernicus and NGA. I would like to do variety of 
the studies, meaning firstly I would like to compare Tomnod and HOT results to 
the reference data separately. Then I would like to compare HOT and Tomnod 
between each other and finally I would like to compare then with 
UNOSAT/Copernicus and NGA results. Couple of questions are arising from my side 
and I think some of you here are capable of helping me out:
1. Is it "meaningful" to make a comparison between the results from Tomnod and 
HOT? Because as I know, Tomnod results were categorized differently than HOT 
ones, but probably I could just choose one category (damage buildings, for 
instance) and focus on this. 
2. Does anyone have an access to the good reference data and willingness to 
share it? By that I mean field survey data, aerial imagery or even UAV data. 
3. If I do not have any of the reference data sources mentioned in question 
no.2, do you think I could use UNOSAT/Copernicus or NGA results as reference 
data instead? I have read some papers in which it was done like that. 
4. Anyone that has saved in his local storage (or online access to) the 
pre-event and post-event imagery of Nepal earthquake that were used for HOT 
assessment? I would need that data in order to load them to my GIS software. 
Again, thank you very much for any kind of help or recommendation. I am very 
much open to the discussion and I hope this study could be useful for HOT 
community itself as well. And if you think another somewhat related study 
should be made as well, please come up with the suggestions as well.
Cheers from Beijing,Michal.

Re: [HOT] Admin Boundary Extraction Service

[augustindoury]

Hi Samuel,

This expression in the Wizard : type:relation AND admin_level=4 AND
is_in='Burkina Faso'
gives you all the relation type=boundary with an admin_level=4.

It gives you this query :

[out:json][timeout:25];
(
  relation["admin_level"="4"]["is_in:country"="Burkina Faso"]({{bbox}});
);
out body;
>;
out skel qt;


If you just want the polygons it's ok to extract this. But you won't
extract the OSM objects members of relations, and their tags neither as
Blake said.

If you want the members to, and avoid JOSM, add :
>>; to get all members
node(r); to get the nodes
way(r); to get all the ways
relation(r); for relations

Example for all members :

[out:json][timeout:25];
(
  relation["admin_level"="4"]["is_in:country"="Burkina Faso"]({{bbox}});
 >>;
);
out body;
>;
out skel qt;

Good luck

Augustin

Thank you Blake,
This looks promising. Even though i use Overpass turbo several times, i haven't 
looked into the overpass api.
I will be happy to receive other suggestions and people's experiences.

 Hi Samuel,

I have used overpass-turbo.eu to extract just admin boundaries before
and it seems to work well.

I then have to pass the results over to JOSM and download the missing
members to get all the points and ways that make up the boundaries,
but that is probably because I do not know overpass-turbo well enough
to have it grab all the elements automatically.

overpass-turbo consists of 2 major parts, the web front (Overpass
Turbo) and the Overpass-API which handles searching OSM data, both are
available from GitHub. Overpass-API works with local .osm.gz files so
it can take a full OSM Planet file and minutely updates and run
totally locally.

https://github.com/tyrasd/overpass-turbo

Probably not the easiest solution to your question, but at least you
can try out Overpass-Turbo and make sure it does what you want before
you try and run it locally.

Here is one I used last week for one of our contacts who needed admin
boundaries for Serbia: http://overpass-turbo.eu/s/cx8

Like, I said, there might be simpler (I hope) answers to your
question, but Overpass is one I think.

Re: [HOT] Admin Boundary Extraction Service

[Jo]

Hi Samuel,

is_in has been deprecated several years ago. The Overpass API has a better
solution:

area[name="Burkina Faso"]->.b;
(
  relation(area.b)["admin_level"];
  way(r);
);

out body;
>;
out skel qt;

If you want to use the result in JOSM:

You can select File/Download from Overpass directly, but with a different
query:

[timeout:100];
area[name="Burkina Faso"]->.b;
(
  relation(area.b)["admin_level"];
  way(r);
);

out meta;
>;
out meta qt;

You have to additionally set a bounding box though.

It is also possible to save this query in a text file, if you need it more
than once, then call it as follows:

"C:\Program Files (x86)\GnuWin32\bin\wget.exe" --timeout 0
--header="accept-encoding: gzip" -O "PT_De_Lijn.osm.zip"
--post-file="boundaries.overpass" "http://overpass-api.de/api/interpreter;

Which you can save as a .cmd file (On Windows), or .sh on Linux (then
simply use wget). To get wget.exe on Windows, you need to install gnutools.

You can drag and drop the .zip file on JOSM directly, if you like.

[HOT] umbrellas

[Daniel Specht]

Your link does not seem to be working.  Can you send the lat/lon of
the object to the list so we can have a look directly?  In josm you
can press ctrl+j or double click on the coordinates in the lower left
corner to get the location.  Not sure how to do it in iD though.

Re: [HOT] Admin Boundary Extraction Service

[Blake Girardot]

Hi Samuel,

I have used overpass-turbo.eu to extract just admin boundaries before
and it seems to work well.

I then have to pass the results over to JOSM and download the missing
members to get all the points and ways that make up the boundaries,
but that is probably because I do not know overpass-turbo well enough
to have it grab all the elements automatically.

overpass-turbo consists of 2 major parts, the web front (Overpass
Turbo) and the Overpass-API which handles searching OSM data, both are
available from GitHub. Overpass-API works with local .osm.gz files so
it can take a full OSM Planet file and minutely updates and run
totally locally.

http://overpass-api.de/
https://github.com/tyrasd/overpass-turbo

Probably not the easiest solution to your question, but at least you
can try out Overpass-Turbo and make sure it does what you want before
you try and run it locally.

Here is one I used last week for one of our contacts who needed admin
boundaries for Serbia: http://overpass-turbo.eu/s/cx8

Like, I said, there might be simpler (I hope) answers to your
question, but Overpass is one I think.

Cheers,
blake

Re: [HOT] Admin Boundary Extraction Service

[Rafael Avila Coya]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hi, Samuel:

Here you have an overpass query to get all boundary relations for all
states, LGA's and wards of Nigeria, with the admin_centre's and label
of each relation when available: http://overpass-turbo.eu/s/cxp

If you want Nigeria country boundary relation too, just change "4|6|8"
by "2|4|6|8". In case you want for example only states and LGA's, just
do "4|6", and so on.

In case you want only the boundaries for a certain state, you can use
this query (this example is for Kano state):
http://overpass-turbo.eu/s/cxt

In case you don't want the admin_centre's nor labels nodes of any
relation, you have to run a different query. This one is for Kano:
http://overpass-turbo.eu/s/cxs

Whenever possible, I advise to use area codes instead names. For
example, Niger is the name of a state in Central Nigeria, but it's
also the name of Nigerias north neighbour country: Niger.

Getting the area code is simple: go to osm.org, search for the area
you are interested in (example Niger), get the relation id we want (in
our case, let's say we want Nigeria's Niger state relation id, so we
click in "State Boundary Niger, Nigeria" link, not in "country,
Niger"), and then we copy it's id (in our example 3718384), and we add
36 + 3718384 = 3603718384 to get the Niger state area code for
overpass queries: (area:3603718384)

To avoid a query to overload your web browser, instead of hitting
"run" button, click in "Export" button instead. There, go to "Query"
and then click on "compact" in the "convert to (compact) OverpassQL"
link. That will open a new window with a compact OverpassQL link.
Click on it and it will make the query and download directly in your
file system the result of the query. For example, for the last example
query (Kano state boundaries without admin_centre's nor labels), the
link is like this one:
http://overpass-api.de/api/interpreter?data=%5Btimeout%3A250%5D%3B%28relation%5B%22boundary%22%3D%22administrative%22%5D%5B%22admin%5Flevel%22%7E%224%7C6%7C8%22%5D%28area%3A3603710302%29%3B%29%2D%3E%2ErelBoundary%3B%28way%28r%2ErelBoundary%29%3B%29%2D%3E%2EwaysBoundary%3B%28node%28w%2EwaysBoundary%29%3B%29%2D%3E%2EnodesBoundary%3B%28%2ErelBoundary%3B%2EwaysBoundary%3B%2EnodesBoundary%3B%29%3Bout%20meta%3B%0A

If you need any more sofisticated query, just let us know:

Cheers,

Rafael.

Re: [HOT] Admin Boundary Extraction Service

[Rafael Avila Coya]

Hi, Satoshi:

The good thing I see is that it is really easy to get the file (no
need of writing any query).

But it updates the files only once in a month, that can be a problem
for people who want the updated OSM boundaries. Also, being only
geojson is maybe not what many people want.

Cheers, and have a nice week,

Rafael.

Hard to say what it is for sure due to the low resolution of the
imagery.  My guess would be tents for people who are tending animals
that they move from valley to valley to forage on what little
vegetation lies along the valley floors.  You can see other small
sites like this in the area, and several have paths leading to them so
it is definitely human settlement of some sort but I can't be sure
exactly what or how to tag them.  You could maybe put a node at the
center with place=isolated_dwelling as I think they are at least this,
but I am not sure beyond that.

Hello,

What about Mapzen's boundary extract?
Format is GeoJSON.

Re: [HOT] Admin Boundary Extraction Service

[Rafael Avila Coya]

That website link is the same that Johan Emilsson gave in a previous
email in this same thread ;)

It's good that this service let's you choose between several different
output formats (although, very surprising, not osm format!)

But it's very inconvenient if you want for example to download, let's
say a Nigerian state with all LGA's (districts) + all wards
(municipalities) of each LGA. Or at least I couldn't see the way, except
selecting one by one every boundary you want to download, something very
time consuming if you have to select 75 districts and around 15 wards
for each of those districts.

Plus, I am not sure how often it updates the data.

Cheers,

Rafael.

[HOT] OSGeo Bangladesh

[Ahasanul Hoque]

Hi,
Through the mail from Kate we got informed that OSGeo has started a new
committee to build a closer relationship with the UN to encourage use of
open-source geospatial software. Then I thought, I should also share that
in Bangladesh there is a OSGeo community group has been formed in last 17
October, 2015 and the first meeting was held at World Bank office Dhaka.

16 participants representing Geospatial, IT and programming professionals
discussed about potentialities, road map of OSGeo in Bangladesh and a
demonestration of open data handling by Django using python. The 3 hours
meeting ended with the decision to enrich the participants in different
geospatial technologies and geospatial languages in a collaborative manner
among themselves followed by launching new projects in near future.
Opensource Geospatial specialist* Ariel Nunez, from GFDRR-World Bank*,
Washington DC presented the potentiality of OSGeo to the interested
participants with openstreetmap data extraction and management examples.

Best regards

Ahasan
