Tessellations do not explicitly store georeferences of the phenomena they represent. A georeference is a coordinate pair from some geographic space, and is also known as a vector. Instead, tesselations provide a georeference of the lower left corner of the raster, for instance, plus an indicator of the raster’s resolution, thereby implicitly providing georeferences for all cells in the raster. In vector representations, georeferences are explicitly associated with the geographic phenomena.
Explain and be able to apply basic vector and raster spatial data structures including selecting a suitable data structure for geographic phenomena (level 1, 2 and 3).
