What is spatial and geo-spatial data?
Spatial data are a kind of data that pertains to the space occupied by objects. Example spatial data from the real world are cities, rivers, roads, states, crop coverage, mountain ranges etc. In the implementation these are represented by points, lines, rectangles, surfaces, volumes and etc. Spatial data have some common characteristics. These type of data are geometric data and in high dimensions. These data can be either discrete (vector) or continuous (raster). GIS applications are applied on these types of data. Geospatial data are spatial data associated with a location relative to the Earth.
