Geographical data are geometrical data or map data, also geographical data represents objects within spatial structure. Vegetation and building, roads, wells are examples of geographical data.
GIS is very effecient to handle geographical objects, wheather these objects are linked to one location (static), or are moving (dynamic) they can be handled using GIS.
Geographical objects can be represented using three geometric types:
- Point
- Line
- Polygon
Some geographical objects has no spatial delimitation and they are represented as continuous surfaces, one example is temperature.
The main purpose of geographical data is to create maps.
