[HOT] Kenyan or African OSM community?

Agreed, we could build off the North Africa tagging page (either incorporate content there, or just rename the page). I'm not sure the best way to capture all of it with a name ... subtropics/tropics doesn't capture all areas which might have this kind of infrastructure, nor do all areas there have this kind of infrastructure (ie Florida vs N India). "Developing Infrastructure" might work? (Of course, any definition of developing is problematic...)

Still tag as a track, I think.

In OSM, we use both imagery from Bing, as well as on the ground survey. Other imagery sources come into play in a crisis. But in any case, the best source for up to date information is local knowledge and engaging people from that area. That's not always easy, but usually quite rewarding.

When are you next in Kenya?

>This is great! I haven't really been mapping much with OSM in Kenya/Africa yet (but more in Sweden, where I currently reside). I organised a Google MapUp in Nairobi last year to map Northern Kenya, my main area of interest: https://plus.google.com/u/0/events/ct2omi1k07uskp8sqc5mkqu7b1k

>The North Africa tagging wiki page is a great start. Several of my questions are already answered there, like seasonal rivers, man-made water wells and residential areas in remote areas. And like Pierre Béland points out, better to categorize roads by their socio-economic importance. There is a wiki page detailing how to map Kenyan roads according to the official classifications: http://wiki.openstreetmap.org/wiki/WikiProject_Kenya. Is there a way to tag roads to show that they require 4WD or that some areas are prone to flooding during rainy season? And what about "roads" in villages, which are used by 4WD cars although in a European country they probably would have been tagged like a path or track? This is the home village of my wife, for example: http://www.openstreetmap.org/#map=16/1.9944/37.9157

>>While working on this wiki page, I insisted about the importance for people from the north to think differently how to map subtropical countries. I think that it is essential to categorize roads by their socio-economic importance. The road surface condition should not take precedence over the importance of the road. 
>>
>>
>>
>>An other aspect is related to the infrastructures. We started to list important infrastructures like wells and water points. However, this needs to be more detailed.
>>
>>This year, the USAID - HOT Cap-Haitien project, north of Haiti, gave the HOT Project team the opportunity to pursue this thinking and develop a Humanitarian Map style. I had the opportunity to work for this project in a "subtropical" context and observe the local reality while the rainy season was approaching and approaching. Our motorbike mapping teams then suffered the road conditions deteriorating rapidly. We also saw the importance to describe activities or infrastructures that are important to the local communities.   The piedestrian paths, the crafts and shops are essential to describe appropriately such towns.

>>The HOT mapcss style that Yohan Boniface and Will Skora are completing presently is focusing on such information and is very usefull to render it appropriately. The maps below talk by themselves.

>>Originally a 'Mali tagging' page was planned, but I suggested generalising more. I guess the process of spotting things in aerial imagery in rural North Africa will be very similar to east africa.
>>
>>...but also pretty similar to south africa, and actually pretty similar to rural india. Not sure how to organise that actually. Maybe "subtropical" regions all
 have a lot in common. http://en.wikipedia.org/wiki/File:Klimagürtel-der-erde.png

>>Aside from that scoping question, I'd say the page could be improved to be more like mapping cheatsheet with actual images for easy reference.

>>> The topic of tagging features specific to African context, good one. Actually really relevant right now, as Map Kibera does more work on sanitation mapping. Why don't we just have that discussion here on this list for now? Can you explain more what kinds of features you've been mapping, and how you've been tagging them? Are you doing remote mapping, or based in Kenya?

 those.
