Architecture of the Information System of Evaluating of the Land Resources Based on Processing of Spatial Data

Headnote

The architecture and the main characteristics of an information system are presented in article, they allow to solve a complex of the problems connected with estimation of a condition of agricultural lands on the basis of processing of spatial data. The system is based on the ontology of estimation of agroeconomic capacity of lands developed by authors.

Keywords: architecture of the information system, ontology of lands evaluation, remote sensing of Earth, agricultural lands, multicriteria evaluation of lands, spatial data.

Introduction

Land evaluation problem is solved in a wide range of practical applications. It affects the areas of human knowledge such as: ecology, economics, landscape science, soil science, crop and others. Review of the literature [1-8] showed high variability of solved problems in this context.

All existing tasks can be divided into two classes: static and dynamic evaluation. In the first case, the goal is to provide an integrated assessment of the current state of the land based on field measurements, knowledge of the history of its use, the state of its infrastructure and other relevant factors. Depending on the peculiarities of the task, the result of solving it may be assessment of the market or cadastral value, assigning quality score, rank in the system of comparative land analysis, etc. In the second case, the goal is to obtain private rapid assessment of the vegetative cover condition or the progress of agro-technical measures. This need arises in the monitoring tasks, the results are used to make management decisions, monitor the effectiveness of measures, budget spending, prediction of crop yields, generation of reports, etc.

Agricultural lands as the object of the study are characterized as a complex, multi-factor object. Their condition depends on climatic factors, the characteristics of the soil and vegetative cover, infrastructure peculiarities, geospatial characteristics of the analyzed sections of the earth's surface, etc. In the scientific literature there are a lot of overlapping systems of land...
