Digitizing raster data and further systematization within geodata base

Vectorization of raster maps with different scales and directions- topographic maps and plans, site plans, restricted zones, forest cover maps. Classification confined to geodatabase.

Selecting and processing ERS raster data (base maps from Yandex, Bing, etc., georeferenced maps)

Visual interpretation of available territorial images in public data source, analysis and selection of satellite images (Yandex, Bing, etc.), downloading zone determination, loading raster data from selected satellites, processing, pasting snapshots (in case if the rasters are from different sources).

Topographic plans and maps processing according to location orthophotomaps and materials of airborne laser scanning

СSpatially topographic mapping and planning scales (from 1:500 to 1: 5000) to orthophotomaps based on the document “Symbols for Topographic Map Scales 1:5000, 1:2000, 1:1000, 1:500”, approved by State Geodesy and Cartography Department, Council of Ministers, USSR, dated 22.11.1986 (Moscow, Nedra, 1989).

Applying airborne laser scanning data to elaborate object numerical characteristics (tree height and calliper, level of water bodies and rivers, etc.), as well as plotting digital terrain model.
