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.

Functions That Read and Write Files in Compressed Formats

Geospatial data are frequently stored and transmitted in compressed or archive formats that can be accessed using standard functions.
