This is from this experience that we did use tools to detect villages in flooded and semi-desertic areas from images and we proposed what is now recognized as the <a href="https://wiki.openstreetmap.org/wiki/Highway_Tag_Africa" rel="nofollow" target="_blank">https://wiki.openstreetmap.org/wiki/Highway_Tag_Africa</a> </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">While responding to major disasters in Democratic Republic of Congo (2012) and North-Mali (2013), we did experience such workflow with <br></div><div dir="ltr" data-setdir="false">1. spot villages / hamlets (ancestor tool of mapswipe)</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">2. trace contour of these populated areas - we want a minimal density of these urbanised areas and need to fix a minimum of buildings <span> adjacent</span> to each other (5-10 buildings should be a minimum). <br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">3. Try to complete the road / path network, trying to correct road islands (not connected to the general road network), structure the network of roads / paths and avoid to trace the multitude of paths in sand left by livestock, and the multitude of alternative paths when people or cars try to contour damage roads at rainy season.<br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">The second problem is to manage such projects and control the quality of mapping. As with the Buildings projects, if too many new mappers participate with no control, we endup creating poor quality data that might never be corrected later. And as we have seen with major mapping projects since 2015, there are initiators adding multitude of Tasking Manager projects, promoting these projects inviting crowdmap participation but with no plan, no volunteers mapping training and management.<br></div><div class="ydpd82f500signature"><div><span style="font-style:italic;color:rgb(0, 0, 191);font-weight:bold;"> </span></div><div dir="ltr" data-setdir="false"><span style="font-style:italic;color:rgb(0, 0, 191);font-weight:bold;"></span>but I would say that areas in semi-desertic areas with a lot of isolated villages are often undermapped and should be prioritized. But please let's avoid replacing a Blank map by bad quality mapping.<br></div><div><br></div><span>And not dozens of projects should be started simultaneously and never validated correctly. We need to redefine Validation of TM projects since too often we see bad quality data even after validators passed over the data.</span><br><div><br></div><div dir="ltr" data-setdir="false"><div><div dir="ltr" data-setdir="false"><span>It would be important that OSM communties from Africa express their opinion on this. <br></span></div></div><div><br></div></div><span style="font-style:italic;color:rgb(0, 0, 191);font-weight:bold;"><font style="background-color: inherit;" face="garamond, new york, times, serif">Pierre </font><br></span></div></div>
