The paper presents scientific and methodological approaches for the application of geostatistics methods and remote sensing data to assess the state of agricultural fields characterized by soil cover heterogeneity. The calculation of the NDVI vegetation index was based on the satellite data. The obtained NDVI values were coordinated with ground measurements. The studies were conducted at the test site of the regional monitoring network in Leningrad Region. It was shown that geostatistical analysis of remote sensing data and the use of spatial differentiation of agricultural technology of satellite monitoring can be used to assess multiple heterogeneous indicators. In some cases, the required assessment can be obtained based on a theoretical approach and presented in analytical form using geostatistics probabilistic mathematical apparatus taking into account the variability of soil-climatic and other factors.
Keywords: remote sensing data, NDVI, geostatistics, variogram analysis, spatial differentiation, space images
