### Edit Stats for OSM Japan

#### by Pascal Neis - Published: March 20th, 2011

Kate created some editing stats for OpenStreetMap Japan last Thursday. You can find her blog post here: “Quick Japan Editing Stats for OpenStreetMap”

During the creation of the layers for the “Road Status in Japan”, I log some editing information of OpenStreetMap too. As I mentioned in my blog post, I use the Geofabrik extracts for Japan (Sendai region only). They have the following bounding box (thx Frederik):

polygon 1 1.412259E+02 3.663895E+01 1.427964E+02 4.038643E+01 1.411296E+02 4.038351E+01 1.394639E+02 3.665750E+01 1.412259E+02 3.663895E+01 END END |

And here are several diagrams of the editing in Japan (Sendai region only):
