FILE TYPES
==================================

DNRGPS supports loading data from or saving data to the following file types:

**ESRI Shapefile** - Only contains one data type (points, lines, or polygons). If the shapefile does not have a prj file, then it assumes data is projected in the projection specified at *File => Set Projection*. Loading from or saving to shapefiles does not require ArcMap.

**Google Keyhole Markup Language (KML File)** - Can store waypoints, tracks, and routes together. For more control over which layers you import, load the KML by connecting to it as a :ref:`database <load_from_kml_database>`. Also, save to a :ref:`database connection <save_to_kml_database>` instead of a file for more control over the name of the target layer. For more on this file format go to http://earth.google.com/kml/

**GPS Exchange Format (GPX File)** - Can store waypoints, tracks, and routes together. For more on this file format go to http://www.topografix.com/gpx.asp

**Text File (comma-delimited)** or **Text File (tab-delimited)** - Can be used to load data or save out data.

**Mapinfo File (.map)** - *This functionality does not yet work.* If no projection information is associated with this file, then it assumes data is projected in the projection specified at *File => Set Projection*.

**Geography Markup Language (GML)** - For more on this file format go to http://www.opengeospatial.org/standards/gml

**Geo JavaScript Object Notation (GeoJSON)** - For more on this file format go to http://geojson.org/
