Blog OpenGeoData was published a short report on how much mapper is actively involved in the project OpenStreetMap or how much editing was done mapper unique in the country. Data were collected for two months with a deadline of September 30. It is not surprising that Germany has won ... there are eight very polpulární. Second place went to Great Britain, a country of origin OSM. Third place France.
For comparison, I created a table in which I took into account the size of the state of active mapper. The result is the number one mapper manages square kilometers. Value sqrt APM / 2 is the value of how much mapper has traveled to get to the territory of his colleagues
APM = Area per Mapper
