-**Spatial data** means any data with a direct or indirect reference to a specific location or geographical area((Directive 2007/2/EC of the European Parliament and of the Council of 14 March 2007 establishing an Infrastructure for Spatial Information in the European Community (INSPIRE).))   . Spatial data can be displayed, manipulated and analysed by means of a spatial attribute that denotes a location on or near the surface of the earth((Yeung A.K.W., Hall G.B. (2007) Spatial Data and Spatial Database Systems. The GeoJournal Library, vol 87. Springer, Dordrecht.))   . [[:wiki:gis|Geographic Information Systems (GIS)]], for their functioning, needs these data in specific formats and data models. The main models used are raster and vector.

 **Raster**: rasters are created on the base of grids. Raster grids are conceptually simple structures, comprising square cells with numeric values or classes attached to each cell((Lloyd, C., (2010) Spatial Data Analysis: An Introduction for GIS Users. Oxford University Press.))   .
