CORRECTION OF IMITATING MODELS OF BIOEFFICIENCY OF GRAIN CROPS WITH USE OF THE DATA OF REMOTE SOUNDING

In article the method of correction of results of imitating models of bioefficiency of grain crops is offered by the example of a winter wheat on the basis are no viscous modeling calculations of an index of sheet surface LAI (Leaf Area Index) and hisvalues designed calculated оn the datato remote sounding (DRS) of agricultural fields. Calculations of bioefficiency of a winter wheat with use of mechanistic model WOFOST and updating of settlement values of a sheet index (LAI) are executed on the basis of a satellite estimation of a vegetative index. In view of correction of results with use DRS accuracy of the forecast of productivity makes about 1,68 c/h.

From visual aerial photo interpretation and field soil survey to automated decoding and soil mapping by satellite imagery

Under consideration are the ways for the development and improvement of methods to compile soil maps in Russia as based upon the information on landforms and the earth surface obtained by different aerial and outer space devices. The ever increasing development of aviation, cosmonautics and modification of electronic engineering resulted in great changes taken place in the soil studies, thus affecting the quality and readability of soil maps. The ways for obtaining and decoding of the satellite imagery are described. The methods to study different characteristics of soil properties are considered as well. The automated methods of soil identification and mapping are realized now through the materials of remote sounding of the Earth’s surface.
