Choose a zipped shapefile from your disk to upload. Then click submit.

The zipped shapefile must be in a projection such that standard ESRI libraries can convert to WGS 84 - Decimal Degrees (e.g. Lat-Lon unprojected).

It should also contain a field called "Name". This field will serve to label the regions. Without this field, the regions will be labeled sequentially.

The attributes in the Name field will become file names on the server and therefore CANNOT contain any special characters such as periods, slashes, or any accent marks such as á, é, ü, etc. They can contain spaces underscores and dashes ( " " , "_" and "-" ).
