Quad Tesseral Addressing
Quad tesseral addressing is an alternative method of defining points in two-dimensional Euclidean space which has some significant advantages over the Cartesian approach.
A form of the tesseral model based on triangles. The vertices of the triangles form irregularly spaced nodes and unlike the DEM, the TIN allows dense information in complex areas, and sparse information in simpler or more homogeneous areas.
While the vector geometry has a large amount of models the raster model even with the newly added extensions [16] does not contain conceptually new ideas (not even the tesseral indexing is allowed).
