Geo Visualization
Geographical data is any data that contains geographical information.
There are 2 categories of geographical information:
- 1.Spatial Objects
- shape and spatial extent matters
- the map is the main object of interest
- for example: counties, regions, buildings, lakes etc.
- 2.Non-Spatial Geolocated Objects
- shape and spatial extent do not matter
- the map is only used as reference
- for example: cars, people, animals, weather stations etc.
- Regions For example: country borders
- Locations For example: latitude, longitude
- Identifiers Names/labels given to spatial objects, for example: zip code, street name, borough
Geocoding is the process of translating an identifier to a specific location (for example state name to location), while Reverse Geocoding is the process of translating a location to an identifier (for example location to state name).
