GIS File Formats
A GIS file format is a standard of encoding geographical information into a file. They are created mainly by government mapping agencies (such as the USGS or National Geospatial-Intelligence Agency) or by GIS software developers.
Metadata often includes:
- Elevation data, either in raster or vector (e.g., contour lines) form
- Shape layers, usually expressed as line drawings, for streets, postal zone boundaries, etc.
- Coordinate system descriptions.
- One or more datums describing the precise shape of the Earth assumed by the coordinates.

Famous quotes containing the word file:
“Probably nothing in the experience of the rank and file of workers causes more bitterness and envy than the realization which comes sooner or later to many of them that they are “stuck” and can go no further.”
—Mary Barnett Gilson (1877–?)
