Global heatmap of HOT contributions, Sept 2016 (with high-res download)
Posted by dekstop on 18 November 2016 in English.The visualisation below shows the regions of the world where the HOT community has contributed edits to OSM, which is one way in which we can show the impact of our community. The chart visualises contributions before 23rd Sept 2016. By this date, 32,000 people had contributed at least one edit, accounting for a total of 182,000,000 edits. This took an estimated 240,000 labour hours.
As mentioned before, I’ve been showing the visualisation in talks for a while now, and I regularly receive messages by people who would like to use it for their own slides, for mapathons and training sessions, and other uses.
There is also a PDF version (11MB), a high-resolution PNG (1.3MB), and a folder with older versions if you want to do a visual comparison of map growth. Send me an email if you would prefer a version without annotations – I simply ask that you provide credit when you’re using it.
(Despite my best efforts I’ve not yet managed to make to switch to the Robinson projection, as recommended by BushmanK… the QGIS renderer acts up every time I try changing the projection string. I’m probably simply doing something wrong.)

World map projections with a split not at 180 degrees longitude - as BushmanK suggested - are a special difficulty - better to start with the basic version here. That should not be a problem - unless your rendering setup really sucks.
Regarding the map itself - looks like quite a clear case of regional bias. The extreme emphasis on sub-saharan Africa is most obvious - but even apart from that this is clearly not a map showing the most serious objective needs for mapping across the world in the past years.

For the purpose of visualization, it is usually more practical to rasterize data with double or quadruple resolution using one of the conventional projections, then - to reproject and downsample this temporary raster.

Have you got any additional info about occasional mapping in Ukraine?
