METHOD OF CALCULATION OF CONSTRUCTION ZONES CONTROLLED shadowing iterates through the DEM RELIEF

摘要

A method of constructing estimated occluded areas controlled enumeration matrix elements elevations, wherein the subject impact received digital map of the area, whose properties are altered by introducing into it the estimated occluded areas characterizing possibility visibility of remote objects from a given observation point produced based on the heights of the terrain averaged in the area of ​​the square, selected as the minimum of the discrete unit of the height difference, summarized in a matrix, tied to the coordinate set e applied coordinate system and enables the coordinates from the map, to select a specific value of the averaged height of the two-dimensional array of DEM, the point of standing object, excess observed object above the terrain and elevation observed objects above the terrain, and which, unlike known methods, forms said shading area by processing data computing steering matrix received and distributed by the matrix positions prior to the construction of computational occluded areas allows at alongside a ystvii information on Digital maps computation to replace the data selection, avoid duplication and eventually to achieve a significant reduction in time to build the estimated occluded areas used in the organization of automated management information collection systems.
