Disaster Ninja is a map of global population density correlated to OpenStreetMap density. It shows the unwrap of OpenStreetMap objects mapped compared to the local population density. The map tin thence hold upward used to apace position populated locations roughly the basis which accept non been fully mapped on OSM.
Disaster Ninja was initially developed to aid disaster relief. The map tin hold upward used to apace create upward one's hear the degree of OSM coverage compared to the local population subsequently a natural disaster. It is thence a useful tool for organizations such equally the Humanitarian OpenStreetMap Team, who prepare together with work OSM map information equally purpose of their disaster reply together with management efforts.
The Disaster Ninja interactive map uses a bivariate choropleth overlay to demo the unwrap of OSM map objects compared to the population per kilometer squared. The carmine areas on the map are locations which accept a high population density together with a depression unwrap of mapped objects on OSM. The carmine areas on the map are thence locations which are probable to non hold upward fully mapped on OpenStreetMap. At the other halt of the bivariate scale are the calorie-free dark-green areas. These are locations amongst a relatively pocket-sized population together with a large unwrap of mapped objects.
At a glance Republic of Republic of India together with PRC appear to hold upward 2 areas of the basis amongst a relatively high population density together with depression OSM map object count. The real high population densities inwards some areas of these countries may partly concern human relationship for this. However some of the almost densely populated areas, such equally New Delhi, Bombay together with Beijing genuinely demo upward equally dark-green on the map together with are thence relatively good mapped on OSM.
