ALGORITHM FOR ANALYSIS OF SPATIAL SCENES ND-OBJECTS IN GEOINFORMATION SYSTEMS
The article developed an algorithm that allows analyzing nd-objects at different time intervals and at different scales. The algorithm of analysis of spatial scenes allows you to see the topological relationship between objects. Unlike geometric, topological characteristics do not depend on the location of objects. The algorithm is based on computer topology methods using the Cech complex. As a result of the implementation of the algorithm, barcodes of spatial objects are cited and analyzed (pp.9-13).
Keywords: spatial object classification, topology, geoinformatics, Barcode.
