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.
Keyhole Markup Language (KML) specifies how a set of geographic features should be displayed in "Earth browsers."
You can import a subset of elements in a shapefile by filtering elements according to attribute names and values.
Geospatial data are frequently stored and transmitted in compressed or archive formats that can be accessed using standard functions.
