3.2.1. Maps

Topographic maps (Fig. 4) are representations of the terrain which include both natural and man-made features, including, relief (in the form of contour lines), towns, villages, roads, and other geographic characteristics (Burrough and McDonnell, 1998). They are those maps which people are most familiar with. In GIS, topographic maps are stored in raster format in their entirety, but can also be broken down into their respective categories (rivers, buildings, roads, etc.) in vector layers.
