Abstract

The authors describe the technology of creating a summary style of displaying digital topographic maps (DTM) for a certain scale. The technology enables subjects of geodesic and cartographic activities that create and process spatial data in the form of DTMs to reduce labor costs at forming coatings from several DTMs made with classifiers of different release years (at different times), as well as their correct visualization. The method consists of five steps, representing both automated processes and those requiring manual work of specialists in the field of digital cartography and geoinformatics. During the development of the technology, several software utilities were established to minimize the time required to make a summary style of the DTM display with newly specified source data. One of the stages is creating a transcoding table of the DTM object composition. It can be used by GIS and information technology developers
