INNOVATIVE TECHNOLOGIES OF GEOINFORMATION SUPPORT FOR MAPPING OF AREA OBJECTS IN THE ARCTIC USING NON-CONTACT METHODS

An important task in remote areas of the Arctic is a mapping of various site objects with their subsequent classification. An example is the mapping of sea-ice fields of different ages in the interests of operational geoinformation support of navigation along the Northern Sea Route. The described mapping in the Arctic is expedient to be solved with the help of non-contact methods, including remote sensing of the Earth. The main sources of non-contact data are the satellite systems Sentinel-1, Landsat7, Landsat8 and MODIS. Features of their application and imposed restrictions are described. As the main source of data, the satellite system Sentinel-1 was chosen, capable of probing the underlying surface under any light and weather conditions, which is especially important when observed during the polar night or in cloud conditions. As a supplement, Landsat7, Landsat8 and MODIS systems were considered, the data of which are able to fill the missing time sections of a single circuit, ensuring continuity of observation over the water area. The analysis of the databases of these systems is given.
