Formalizing the land inventory process for information support of land projects management

The subject of study in this work is the land inventory process. The work increases the efficiency of the land inventory process by finding the possibility of reducing the amount of topographic surveying work by algorithmizing and systematizing the information flows with a combination of qualitatively different data. Objectives: to analyze the land inventory process within land management projects to identify possible ways of its efficiency improvement; focusing on information flows, to create an information model for the inventory process; to develop scientific-methodological basis for information support of land management projects to reduce the amount of topographic surveying for implementation into decision support systems for land management. The following results were obtained. The requirements of the current legislation on the inventory of land plots and related tasks are generalized. A set-theoretic model of information flows of the inventory process, which combines the approaches of functional modeling, is proposed. It allows us to combine the qualitatively different data, consider their dynamic nature and the logic of interaction. IDEF3-model developed. This model considers remote sensing data as a source of accurate and up-to-date information, algorithmizes the mechanism of their combination with other information about land plots and explains the dynamic nature of its changes with time. A method for creating a database of the working inventory land plan is proposed. It combines information about land plots from several sources, reduces the amount of topographic surveying by selecting plots that needed to be coordinated (determined) with the geospatial data. The developed scientific-methodological basis of information support for land projects forms the structure of information technology for land inventory. Its usage will reduce the number of resources required for the implementation of land projects, at the same time forming reliable conclusions about the state of the land by using geographic information systems (GIS) and combining dissimilar data. Conclusions. The results of the bibliographic search confirmed the following. The effectiveness of the land inventory process, which ensures compliance with legislation in the field of land management, is very difficult because of the need to analyze a large amount of different information appears, which may contain errors, inconsistent and contradictory data. This requires the development of specialized models and method focused on the use of GIS for their implementation into decision support systems for land management. Scientific-methodological basis of information support for land projects during the inventory of land plots has been developed, practical usage of which confirmed that the time costs for obtaining the land plot research data decreased by almost 33% and the accuracy of measuring geometric dimensions of the land plot increased by about 1%.
