[HOT] Identification of Communication towers

[spatialbits]

Hi hotties,

as part of tasks #944/943 (Vanuatu) mapping of Communication towers is
requested.
Could someone point me to an example in the imagery (e.g. lat/lon), so I
get an idea on what to look for.

Thanks.

Martin

This is an important feature and quite uneasy job from vertical view and grayed 
/ imprecised images. But when there is shadow, this greatly helps to spot the 
towers.  Since Mapbox is of lower resolution, it might be harder to spot 
comparatively to Bing.

See

Hi Martin,

These are challenging to spot and hard to tag correctly without local 
knowledge I just discovered.


http://wiki.openstreetmap.org/wiki/Tag:man_made%3Dcommunications_tower

I usually find towers by seeing the shadow they cast, that is the big 
indicator to me.


Here are a few examples in the region:

https://www.openstreetmap.org/#map=19/-21.90198/166.072485

If you look very carefully at the shadow you can see the microwave 
transceiver drums in the shadow. I would guess that is what helped the 
person identify this one as a "communications" tower specifically.




https://www.openstreetmap.org/#map=19/-20.748846/167.262194

That one again, shows the shadow being a pretty big factor. And it also 
show a typical service road and pad. I do not know how the mapper knew 
it was a communications tower.

We could make a quick tracing guide for these towers. Just need a few clipped 
screenshots of the imagery, and help text. 
Would put it together in something like this:

Good idea Mike. If somebody want to look at this.

we will enhance the map.

Re: [HOT] Vanuata Islands, Pam Cyclone

[Pierre Béland]

Great Crowdsourcing effort from the community again. Thanks to all for this 
quick response. Be assure that the International community is quite happy about 
this.
We repeated what we did for the first day of the Ebola response. In 20 hours, 
we covered all the priority islands to map (both jobs are about 99% completed). 
 

There are no discussions yet with our partners about the next steps that would 
be necessary.

Validation + Communication towers + landing areas

I want to enhance the map while we do the validation step. Please, follow the 
following intructions :
- Spot communication towers even if this is uneasy- For each village, assure 
that a common space has been added (leisure=common) and trace major buildings
http://tasks.hotosm.org/project/943
http://tasks.hotosm.org/project/944

Coordination with the DHNetwork
We started a Skype communication room a few hours ago with the DHNetwork 
partners.  Still incomplete News with the communication problems, the bad 
weather and all the remote villages. An update indicates that many villages 
were swept (up to 90% destroyed).
Jean-Guilhem collaborates with Jus Mackinnon to prepare an Impact map showing 
pictures of various areas.

Data Exports
 The HOT Exports will let us offer map export updates. Could somebody prepare 
an export in obf format for OSMAnd?

cheers

Re: [HOT] Identification of Communication towers

Ya, that is kind of what I had in mind. It is a good question that was 
asked, I have been trying to think of some more features that could use 
some short example guides and towers are perfect for that and are needed.

Hi Rafael,

Are your pictures geotagged or can they be it you have traces? We could set
a georss with them. I would document how to do it with Flickr and uMap.

Sincerely,

The tag natural=beach is the recommended tag for actual beaches.  The
common areas are different.  Generally they are rectangular area that
is covered in grass like a small park.  I don't see so many of these
in Vanautu like we do in west Africa though, so there may not be so
many to map.  Of course map them if they are there, but don't expect
that they must be there.

[Pierre Béland]

The extent of the disaster zone to cover from the north to the south is 650 km 
long. The post-assessment evaluation will be difficult and the pre-disaster 
informations should be very usefull for the response.
In this context, we want to trace all the buildings. This will be difficult 
with the dense tropical forests and  the MapBox imagery lower resolution as 
compared to Bing. Use Bing wherever it is available. Complete with MapBox. In 
the Task Manager Job 945, we provide instructions to facilitate tracing with 
MapBox. This is a little hack with specifying tms:17.

Please do your best and thanks again for your effort.

If you are looking for a collaborative approach to collect/maintain
the data have a look at http://geogig.org/
I think that could be better suited for "your kind of data" than the OSM format.

just my 2 cents.

*Data Exports

The HOT Exports will let us offer map export updates. Could somebody
prepare an export in obf format for OSMAnd?




I created an .obf file for Vanatu taken from the most recent 
2015-03-14-21:22:02 GMT Geofabrik Oceania extract.


https://www.dropbox.com/s/fuf7bcz4mr6jjya/Vanatu_2015-03-14T212202Z.obf?dl=0

I tested it locally in OSMAnd and it worked fine.

Re: [HOT] Vanuata Islands, Pam Cyclone

[Rafael Avila Coya]

Hi, Severin:

By 2010 I had my first smartphone, but unfortunately I took almost all
my pictures with a camera, so no geolocation.

I have many pictures that show a long way around Tanna island in the
south, and others of hamlets, small villages.

I can only geolocalize a few of them, using my memory and some waypoints
that I still have in my Garmin. I remember to get some tracks, but it
seems that I deleted them or can't find them.

I'm using some of this info for mapping in Tanna. I have more photos of
Espiritu Santo and the Torres group in the North, but those islands it
seems they weren't affected.

I am uploading photos here:
https://www.flickr.com/photos/ravilacoya/sets/72157649035295124/

Cheers,

Rafael.

Re: [HOT] Identification of Communication towers

Quick first version up on Vanuata tracing guide.

  Just one tip so far on comms towers. Let me know what else this should cover. 
Best would be cropped screenshots and text added to this GitHub issue.

some short example guides and towers are perfect for that and are needed.

Hi everyone,

I want to let you know I just got done updating the Vanuatu specific 
data exports from OSM we provide to the humanitarian organizations 
responding to Vanuatu.


You have more than doubled the amount of map data in OSM about this 
nation in a little less than 24 hours!


Congratulations!

Once again the HOT community is rising to a challenge and it is not 
going unnoticed by our current and future partners on the ground.


Cheers,
Blake

Re: [HOT] Vanuata Islands, Pam Cyclone

[Rob James]

There are several Canadians (mostly MDs, families) with recent field
experience on Tanna - very very hard hit. I am starting to document key
strategic assets (landing sites for rotary wing) hospital, etc. but also
trying to document location of small indigenous "tribes" on island. Hope to
have that working tomorrow Vancouver time.
