about spatial data

Spatial data, also known as geodata, is any data which has a spatial component associated with it. Maps, aerial photographs, address lists, road networks, population information and census demographics are all considered as spatial data.

Spatial data has existed in various forms over the years, though today spatial data is most commonly found within a GIS (Geographical Information System). A GIS could be considered to as a hybrid between graphical software (like AutoCAD) and database software (like MS Access) in that it permits the management of textual and graphical information in tandem.

Spatial data comes in various forms:
Vector data [editable graphical data to which information can be attached]
  • Lines - used to represent and store information on linear features like roads
  • Points - used to represent and store information on point features like houses
  • Polygons - used to represent and store information on region features like census districts
Raster data [dumb graphical data to which little information can be attached]
  • Images - used to represent and store information on image features like maps or photographs
  • Grids – used to represent and store numeric information like ground heights or land use
