Hi, We've updated http://disaster.ninja/live/ to use fresh 2019 release of GHSL dataset. Mountains in Switzerland aren't populated anymore. Chinese mountain regions are also better detailed. Have a good day! Darafei Kontur.io On Sun, Jul 7, 2019 at 3:23 PM Christoph Hormann wrote: > On

Excelent and inteligent initiative Darafei. Measuring "density of OSM data" per "Population density" is a powerful metric to analyse where is it lacking more mapping in OSM. It's a nice effort to minimize "inequality" in OSM map. (for more info, see "World Inequality Database" at

Good morning, As an aside, I've heard at a conference that the amount of data in the OpenStreetMap database per capita in a country is proportional to the per capita income [1] of the country. I wonder if there is an inverse relationship. For example, if we take a country and map it

There is another side to this the population counts often depend on building counts but some towns and villages are growing rapidly.  You can see the difference sometimes going from one zoom level tile to the next so the ones with buildings in often haven't the newer buildings mapped but just

Speaking more generally, Populatation is growing fast in Africa and many african countries dont have the resources to organize regular census. See the UN Statistics Division record of last census by country https://unstats.un.org/unsd/demographic/sources/census/censusdates.htm This means that
