The territory of Moscow increased its area 2.4 times, after the land to the southwest of the capital with rather low total population has been adjoined to the city in 2012. Change in the status of the adjoined territories alters their economic, social and geographical position, the configuration of transport network, increase in house-building and population of settlements, change in land use, the increasing anthropogenic load on the environment, etc. In regard to this the Cartography and Geoinformatics department of the Lomonosov Moscow State University in 2013 launched a project aimed in creation a series of maps for integrated environmental and geographical land assessment of the new Moscow territories. This implies the development of information support for a comprehensive assessment of natural and human-made environment, the intensity of land use and population occupancy with the aid of geotechnology and online technologies, including geoprocessing operations and remote sensing data, implemented in geographic information system (GIS). The first scientific and methodological research and mapping results cover three key areas: 1)developing the structure and content of the thematic geodatabase with identifying the information products and the research question of current natural environmental and economic mapping; 2) elaboration of methods for remote sensing data application, including the use of very high resolution images of visible range for detailed mapping and thermal imagery use for the thermal structure of the territory revealing; 3) implementation of a pilot web-based application for the development of geoinformation and online technologies to place and visualize the created maps and other temporal and spatial information, presented in the geodatabase.
