*An ESRI Grid is a proprietary format for a raster dataset that
defines space as an array of equally sized cells
arranged in rows and columns. Each cell contains
an attribute value and location coordinates. Unlike a
vector structure, which stores coordinates explicitly,
raster coordinates are contained in the ordering of the
matrix. Groups of cells that share the same value
represent the same type of geographic feature.
**A Shapefile
is a published, but proprietary, data format from
the Environmental Systems Research Institute, Inc. (ESRI).
***Zip
is a common type of file compression.
