1. Generalisation is necessary because it simplifies the map. Makes it easier to produce.
2. Maps get more generalised the higher the scale.
3. As scale decreases the features get less details.
4. Simplification features have three dimensions such as length, width, and height. Elements that remain depends on the purpose of the map. And it loses the third dimension.
Selection elements remaining depends on the purpose of the map, and the scale of the map. Higher scale results in fewer details and features.
5.The three types of data classificationa are: Nominal, Ordinal and Interval.
GRASS GIS (Geographic Resources Analysis Support System) is a free, open source geographical information system (GIS) capable of handling raster, topological vector, image processing, and graphic data.
Commonly referred to as GRASS, this is free Geographic Information System (GIS) software used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies. GRASS is an official project of the Open Source Geospatial Foundation.
Originally developed by the U.S. Army Construction Engineering Research Laboratories, GRASS (Geographic Resources Analysis Support System) is a raster/vector GIS, image processing system, and graphics production system. GRASS contains over 350 programs and tools to render maps and images on monitor and paper; manipulate raster, vector, and sites data; process multi spectral 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.
