Ретроспективный анализ и особенности создания цифровых инженерно-хозяйственных карт муниципальных образований (на примере МО Иркутской области)

Abstract

The article considers retrospective, modern and prospective ideas about the types of data sources for engineering mapping with economic applications, examples of the selection of source materials and cartographic documents for creating economic engineering maps of various types, including the prepa-ration of a unified electronic cartographic base, data of remote sensing of the Earth from space and aerial pho-tography. The retrospective analysis of cartographic works differs from other research methods in that it compares the planned results with the achieved results, and also takes into account the existing expe-rience in creating maps, which makes it possible to optimize and regulate the mapping technology in the future. The advantages of modern sources of spatial data, their relationship with each other and their content of thematic information for solving specific engineering problems of forestry, agriculture, land cadastre are reflected. Also indicators of optimal management of the municipal territories in the Irkutsk region and the study of natural and ecological complexes of all Baikal areas are noted. Based on the retrospective analysis the article reflects the method of choosing the scale of the created map and the selection of materials, corresponding to it, and considers the main combinations used for the synthesis of multispectral images for the purpose of engineering mapping.
