Keyword: «topographic maps»

Based on the analysis of theoretical material pattern recognition theory, the authors of the algorithm and software was created by performing a search, identification and grouping of text and graphic symbols on maps to solve the problem of building geographic information systems areas. To find the optimum detection method, a comparison was made of three basic methods: comparison matrix, selection of features and intelligent method of artificial neural networks; developed algorithms for pre-processing and post-processing. The best quality has shown the method of artificial neural networks, and it is recommended for character recognition in solving the problem.

The article presents some ways and methods of transferring the earth’s surface to a plane in the form of topographic plans and maps. Most of them require a scientific approach when choosing the types and methods of scanning land plots, creating and using technical means to increase the accuracy, efficiency, and density of information when creating topographic maps.
