Matrix of layers building order |
Matrix legend file preparation. Filling all sections of the legend file in according to the available information. The semantic codes should be filled pursuant to the classifier. Preparation of the semantic information in classifier. Formation the indispensable semantic characteristics with the filled properties. Creation of the vector map object containing the set of indispensable semantics. The classifier should correspond to matrix legend. The initial information preparation. Check the data correctness (overall dimensions of region, error of scheduled position coordinates and absolute height). An estimation of the necessity of usage the matrix of heights. Check the conformity and dimension the powers of layers. Matrix building. It is necessary to allow, that the sequence of layers and their quantity is determined by a legend, instead of the initial information at matrix building. If the information is represented not correctly, the building program will use the data pursuant to a legend. That is, if there is more layers, than it is indicated in a legend, their number will be reduced, and if there is less layers, the powers of missing layers will be set into zero.
