METHOD FOR EXTRACTING INFORMATION ON THE TOPOLOGY OF AN N-DIMENSIONAL MAP.

Currently there are many spatial structures for storing information about raster and vector maps. There are many algorithms for calculating map information, each of which is applicable to a specific industry. Nowthere is a problem of the lack of a universal algorithm for obtaining information about the maps, which will allow you to store its scale, time of image creation, deformation, various rotations and other topological features of objects in the images.The article sets the task of developing a method for extracting information about the topology of an n-dimensional map. The method allows you to extract information obtained using simplicial complexes and methods of persistent homology. Various images are processed at different scales, at different angles and for different times. The result of the algorithm is a structure that stores all the extracted information from the maps. This structure allows you to get the necessary information about the map or object on it at any time.In this paper, an analysis is made of various approaches to calculating and structuring information about mapsand the advantages and disadvantages are identified. In the workvarious satellite images with spatial objects were investigated, their analysis and extraction of topological information was performed.The developed method allows you to get the following information from maps: scale, time, deformation of objects and any other topological changes. More than 100 satellite images were analyzed.This method can be used to analyze satellite images of the Arctic, images of buildings and various natural areas. Itwill allow you to structure the information on the images and objects on them. [ABSTRACT FROM AUTHOR]
