[Talk-ht] Onboarding new mappers

There is a huge amount of stuff to map in rural areas.

1.       Install java en download JOSM

2.       Install the WMS plug-in

3.       Choose a rural area somewhere, not to big and download data

4.       play around and study JOSM for an hour or so, ask questions if you need to

5.       Install WMS layers "best aerial" and TOPO 50K

6.       JOSM may shift layers so as to align them, to already avalaible data : the topo map below is less then 100 meter off however.

7.       compare and map rivers, hamlets, roads (most tracks anyway)  land slidings , important buildings mountain peaks

8.       The tope map gives you a wealth  of names and places and mountains peaks to map

9.       The areal pictures show you roads, buildings and rivers (depends on available resolution in your area)

10.   Study, compare and add missing items

11.   Report the area you are working on to this list (topo map  reference lines ?) to avoid duplicates

WMS links for JOSM

best aerial :  http://hypercube.telascience.org/cgi-bin/mapserv?map=/geo/haiti/mapfiles/4326.map&layers=haiti-best&request=GetMap&version=1.0.0&styles=&format=image/jpeg&service=WMS&

topomap 1:50K (all of Haiti)

http://hypercube.telascience.org/cgi-bin/mapserv?map=/home/ortelius/haiti/haiti.map&layers=haiti-tlm-50&request=GetMap&version=1.0.0&styles=&format=image/jpeg&service=WMS&

Well you also might map using the potlatch editor, but you won't have 2 layers to switch to,

and while potlatch is easier to start with ..... JOSM will do much better and accurate mapping,

and has some features (like Q : make a building or area square-angled) and add-node-on-the fly

You should see me mapping rivers / areas with that, that you will miss very much.

Oh, do not forget to connect roads to roads, other wise a router may never find them.

Loose roads are of no use .

 Well, see for yourself.

Hi, 

please don't try to import/merge Health Facilties manually. We have a plan to import/merge v2 of the list later. This is rather not a task for people onboarding to the Haiti Relief Effort, unless they have good scripting skills we would, of course, be happy to benefit from. I'm currently cleaning up the Humanitarian Data Model for Health Facilities, which has become the most mature part of the HDM. I've also created mapping to the PAHO model, see http://wiki.openstreetmap.org/wiki/Humanitarian_OSM_Tags/Humanitarian_Data_Model/MappingHdmPaho.

I feel that we soon reach a state where we can import v2 with a tag set which can be claimed "fully compliant with HDM". 

amenity=hospital is discurated for health facilites in general. HDM currently assumes that three types of health facilites will be tagged with amentiy=hospital ( @Jean-Guilhem Cailton: field hospitals too, this will solve your issue) 

There is a list of potential duplicates I've identified. PAHO and other involded organisation are aware of them, Jean-Guilhem and Kate are liaising with them. Lets wait for the next consolidated master list which, hopefully, will include less duplicates. Besides OSM there are dozens of other organisations working of data reconcilation regarding Health Facilities. We are now at a state where it doesn't  make sense to "deduplicate" in the OSM database. It would be helpful, though, to *identify* duplicate Health Facilities and flag them as such in OSM, see this link 
http://wiki.openstreetmap.org/wiki/WikiProject_Haiti/Status/Hospitals#How_to_deal_with_duplicate_entries
for how to do that.

A few suggestions:

- Help could be welcome to continue cleaning up the Haiti Health Facilities (HHF) list. As described on
http://wiki.openstreetmap.org/wiki/WikiProject_Haiti/Status/Hospitals
a master list is available on
http://sites.google.com/a/netspective.org/haiti-health-facilities/
Version 1 has been integrated into OSM (to the extent possible, due to duplicates.)

Karl has prepared a .osm file containing version 2 (the last one currently available, with tags modified as also described on 
http://wiki.openstreetmap.org/wiki/Humanitarian_OSM_Tags/Humanitarian_Data_Model
and I think he is working on scripts to import this version 2. (Which still contains many duplicates.)

If you are interested, I could forward to you work spreadsheets from health specialists, which could help bringing HHF in OSM to the equivalent of a version 2.5, while awaiting for version 3 of the master list to be released.

While dedicated tagging (particularly with health_facility:type=*) precisely follows the HHF master list categories, I suggest using, in a ad-hoc fashion for Haiti, "amenity=hospital" for the HHF in general (maybe temporarily), so that they show, with a red cross and at zoom levels allowing a sufficiently large area to be seen at once, on the map at www.openstreetmap.org that OSM outsiders are most likely to consult first.

- An important request from the government of Haiti requesting an IDP database was transmitted to the CrisisMappers mailing list. IDP camps are available from various sources (OCHA, UNOSAT, JRC, Chinese Academy of Sciences, OSM contributors, etc...) It would certainly not hurt to have them reviewed, merged and integrated in OSM.

- Mapping the slums. See :
http://wiki.openstreetmap.org/wiki/WikiProject_Haiti/Tasks_and_Ideas#Currently_for_Haiti_-_.22Now.22

I think this could keep quite a few volunteers usefully busy for a while. :)
(and I still have other ideas, if needed.)

Best regards,

Jean-Guilhem

Thanks for checking in ... I'm not sure what's the most pressing need right now .. can anyone suggest more tasks? Or are we reaching a plateau for now?

Subject: [Talk-ht] Onboarding new mappers

I'm the point person at Crisis Camp Chicago for onboarding vols to help with mapping Haiti (though have no mapping experience). I've developed a 101 guide based on info I've sifted through on wiki pages. For fun, I completed tutorials and attempted to practice so I could field questions from vols. However, it is difficult for me to find items that are not mapped. Seems like whatever I click on has been mapped and tagged. What am I missing? Are people just responding quickly to documented tasks and getting it done?

Tony
