Technology for creating electronic soil maps based on archival materials for land management engineering

摘要

The article considers the structural and logical scheme of the methodology for creating electronic soil maps for land management engineering based on analog archival cartographic materials. The proposed scheme includes seven blocks: 1) building frames for 1:50,000 scale topographic map sheets in the geoinformation environment “Map 2011”; 2) scanning analog topographic maps with a scale of 1:50000; 3) binding a bitmap images of topographic maps to the sheet frames and cropping the frame image; 4) converting data from the GIS “Map 2011” to the GIS “MapInfo”; 5) scanning of archive analogue 1:10,000 scale soil maps and their binding to electronic 1:50000 topographic map in GIS “MapInfo”; 6) defining precision of referencing the raster 1:10,000 scale soil map to topographic 1:50,000 scale map; 7) bitmap image vectorization of a 1:10000 scale soil map in the GIS “MapInfo”. The content of methodology’s each block is disclosed. The developed methodology can be used for cartographic support of land management engineering and territorial planning.
