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:
“A common and natural result of an undue respect for law is, that you may see a file of soldiers, colonel, captain, corporal, privates, powder-monkeys, and all, marching in admirable order over hill and dale to the wars, against their wills, ay, against their common sense and consciences, which makes it very steep marching indeed, and produces a palpitation of the heart.”
—Henry David Thoreau (1817–1862)
