  • Export Vector Geodata

    You can export geodata as a shapefile, which can be exchanged between different geographic information systems. You can also create KML files to upload geodata to the web.

  • Export KML Files for Viewing in Earth Browsers

    Keyhole Markup Language (KML) specifies how a set of geographic features should be displayed in "Earth browsers".

  • Select Shapefile Data to Read

    You can import a subset of elements in a shapefile by filtering elements according to attribute names and values.
