About MyGeodata Converter

Our online converter of Topological GeoJSON format to JavaScript Object Notation format (TopoJSON to GeoJSON) is fast and easy to use tool for both individual and batch conversions. Converter also supports more than 90 others vector and rasters GIS/CAD formats and more than 3 000 coordinate reference systems. If the coordinate system of your input data is not present or not recognized correctly, it is possible to assign the correct one. Then it is possible to transform your data to any other coordinate reference system.

Files can be uploaded using multiple selections or packed into any supported format (ZIP, RAR, 7Z, TAR, GZIP). If the input format is directory-based, it is necessary to pack whole directory - not only the content.

To avoid considerable servers loads we had to set conversions limits for each user - please see Free plan. If you exceeded the limit, you may register a prepaid plan - otherwise you will be charged by credit card during the conversion process (one-off payment). Your charges allow us to cover costs associated with the servers operation and to improve our service.
