The blog OpenGeoData was published a short report on how much MAPER is actively involved in the project OpenStreetMap, or how much editing was done MAPER unique in the country. Data were collected over two months with a deadline of September 30. It is not surprising that prevailed in Germany ... There are eight very polpulární. The 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 active area of the country MAPER. The result is so much one manages MAPER square kilometers. Value sqrt APM / 2 value is much MAPER has traveled to get to the territory of his colleagues
APM = Area per Mapper
