GRASS GIS Tutorial Vector and Imagery Commands

GRASS Introduction 

GRASS (Geographic Resources Analysis Support System) is a raster based GIS, vector GIS, image processing system, and graphics production system.

GRASS Ref. Manual

GRASS contains over 200 programs and tools
to render maps and images on monitor and paper; manipulate raster, vector, and sites data; process multispectral image data; and create, manage, and store spatial data. GRASS uses both an intuitive windows interface as well as command line syntax for ease of operations. GRASS can interface with commercial printers, plotters, digitizers, and databases to develop new data as well as manage existing data. GRASS is ideal for use in engineering and land planning applications.

GRASS is ideal for use in engineering and land planning applications. Like other GIS packages, GRASS can display and manipulate vector data for roads, streams, boundaries, and other features. GRASS can also be used to keep maps updated with its integral digitizing functions. Another feature of GRASS is its ability to use raster, or cell, data.
