GRID is a raster or cell-based geo-processing toolbox
that is integrated with Arc/Info. GRID provides tools
for both simple and complex grid-cell analysis. It represents
space from a location perspective (dividing space into
discrete units called cells) and can accurately portray
continuous surfaces. The commands and functions of GRID
have been designed to optimize these representations,
which allows for greater analytical capabilities. In
conjunction with the other spatial representations and
tools available in Arc/Info, GRID provides a powerful
environment in which to explore spatial problems
