AUTOMATION AND USE OF RETROSPECTIVE MAPS OF LAND REGISTRATION
The article presents the results of the use of retrospective cartographic materials for land use registration in the geoinformation study of nature management and transformation of natural landscapes in the central part of the Lake Baikal basin in the 20th century. Comprehensive comparative analysis of retrospective maps with modern maps similar to thematic content and scale is given. The characteristics of retrospective maps are given, their suitability as documents for long-term monitoring of regional nature management and transformation of natural landscapes is assessed. A methodology for geometric correction of retrospective object layers in the Arc GIS software environment was developed. A technique for automating retrospective maps based on geoinformation technology has been developed. An example of the final map of land use monitoring in the Lake Baikal basin is presented.
