About the state soil map of Kamchatka at 1: 1 000 000 scale

A semi-centennial history of compiling the State soil map of Kamchatka is described; the reasons for its correcting and partial alterating are shown including new data about soils and regularities in the soil development in this peninsula, particular ashes distribution in the region, available satellite imagery of high resolution. The map was compiled in traditional paper version by using multizonal aerospace Landsat images, geological maps at 1:1 000 000 and 1: 5 000 000 scales, a hypsometric map at 1: 1 000 000 scale, the published materials about soils, the vegetation cover and the soil-ash mantle. In general, Kamchatka and its separate regions have been so far examined insufficiently and the compilation of the State soil map assumes an expert character being based upon the comprehensive analysis of different available information on soils. As an example the swampy West-Kamchatka (Pre-Okhotsk) lowland is considered. A list of soils demonstrating on this map is given to show 26 soils, 4 grades according to the particle-size distribution and 2 grades according to the lithologic-mineralogical composition of compacted soil-forming rocks and their genesis.
