Looks like companies switching to OpenStreetMap powered maps is driving OpenStreetMap contributor numbers up. Kai Krueger reports on the osm-talk mailing list an increase in new contributors of over 50% this week:

This week (beginning on the 1st of March) there were a little more than 2300 mappers who have contributed the first time to OpenStreetMap. This is considerable more than the average of 1300 - 1400 new mappers per week in the recent past.

This can be a lot of fun and we are encouraging other organizations to get more involved in OpenStreetMap. We are currently in a four-week mapping sprint with six people, mapping in places such as Mexico City, Guadalajara, São Paulo, Campo Grande, Istanbul, Bandung and Madison.

OpenStreetMap Mapping Party

Here is an example of Campo Grande, Brazil that we have worked on - a good part of the progress you are seeing is from Campo Grande local muzito, who has recently gotten very busy on OpenStreetMap, too.


Here is an example of Itaguai, Brazil where we’ve added all residential streets in the area.
