Qualities raster

Qualities raster is raster model of region received by the analysis of the of terrain objects properties, gradation them on given levels and filling the raster elements by the conforming color. Maximum number of levels is 255, from 1 up to 255. The level 0 means absence of the data.

The raster element corresponds to a square region lot (elementary lot),  which side size is set at raster creation.

The quality raster element contains property level number of map object   disposed on the corresponding  elementary lot. Conformity of the object properties to level number and level color are set at raster creation.

The superposition may  be at displaying objects in a raster, i.e. location  into the same element  of two or more objects. The information of each following object substitutes the information of previous object in case of superposition. The object processing  runs in the order of their displaying. The object displayd above other objects, is processed later.
