Algorithm for Taking into Account the Spatial Heterogeneity of Irrigated Sites’ Initial Characteristics Based on GIS-Technologies

Abstract

Theoretical foundations for creating systems to initiate the implementation of a precision farming concept using the latest achievements in the field of GIS-technologies have been developed. The expansion of precision farming principles in the field of land reclamation technologies is due to the necessity for taking into account the spatial heterogeneity of the initial characteristics of reclaimed lands on the basis of a specific, sectoral set of criteria and indicators. A conceptual scheme for allocating territorial control units based on the data on the intrafield heterogeneity of the indicator is proposed, an algorithm for grouping spatial data to estimate the boundaries and spatial position of territorial control units based on GIS-technologies is developed, and two basic schemes of a site survey for allocating territorial control units are considered. The proposed algorithm, implemented on the basis of last generation geographic information technologies, makes it possible to effectively solve the problem of allocating territorial control units, i.e., a key problem in taking into account the spatial heterogeneity of an irrigated area’s initial characteristics, which is of direct applied value for the creation of precision irrigation technologies.
