Data bases
Geographic vector data bases often are collections of maps, in which elements are grouped in layers (coverages) according to the type of information (roads, buildings, hydrography, settlements, harbours, relief etc.). Layers are connected with each other with the help of the real World coordinates.
These maps usually have attributive information. That means for example, a street is not only a 12.4 cm long line on the screen but there is additional information available on its name, actual width, pavement etc.
Databases are widely used for analysis purposes. With the help of specialized software, like ArcView, we can calculate for example, the shortest and most convenient way from the office to the customer.
