Improved model for formation of views in geospatial information processing systems

Abstract

The subject of research in the work is a model of the formation of species images in systems for processing geospatial information. The purpose of the article is to improve the model of formation of species images in systems for processing geospatial information, which will take into account the shortcomings of existing models of formation of species images. The advantages of obtaining and application of geospatial information are given. It has been established that in systems for processing geospatial information for various purposes at different stages, data of various types are processed, however, they are structurally isomorphic - geospatial information structures. To solve the problem of representing heterogeneous software engineering technologies in a unified form, convenient for their integration and coordination within the general cycle of software systems design, the mathematical apparatus of category theory has recently been used. The existing models of the formation of species images in systems for processing geospatial information, their disadvantages and advantages are considered. The considered mathematical model of the formation of a view image in general form can be presented as a result of the action of an operator performing the transformation of coordinates and operators determining the brightness of the corresponding image element for a given element of the earth's surface in the spectral channel. An improved model of the formation of species images is proposed, which simultaneously takes into account the transformation of geospatial coordinates into image coordinates and the transformation of brightness due to the properties of objects on the earth's surface and the processes of the passage of solar radiation in the atmosphere, provides the possibility of correct processing and analysis of species images in geospatial information processing systems.
