SPATIAL DATABASES

Spatial Database Systems (SDB) are usually part of, and sometimes considered equivalent to, Geographic Information Systems(GIS).

Many different fields are involved in the development of GIS and SDB:

Cartography
Civil Engineering
Computer Science
Geodesy
Geography
Mathematics
Surveying
......

Some typical queries in GIS systems are:

What feature is at location X?
Where is feature F?
Where is A with respect to B?
What is the path between A and B?
What is the shorstest distance between A and B?
What is the combination of features at location X?
