Proposals for extension of nomenclature of types of border signs for administrative-territorial units

The purpose of the work is to substantiate methodological approaches for the development of scientific and technological recommendations for determining the optimal types of boundary markers for the establishment (consolidation) of the boundaries of administrative-territorial units. Method. Methods of historical analysis of constructions of boundary signs are used for researches, in particular: influence on constructions of boundary signs of natural and climatic conditions; requirements of land cadastres in different historical periods; research of interdependence of the centers of geodetic points and properties of soil on a choice of the centers of boundary signs. Results. An expanded nomenclature of types of boundary markers is proposed, which takes into account the properties of local soils through which the boundary of the administrative-territorial unit runs, and proposals for the selection of appropriate materials for the manufacture of boundary markers to increase their shelf life. This will allow more efficient management of land resources of administrative-territorial entities. The developed proposals can be reflected in land management projects to establish (change) the boundaries of administrative-territorial units, in particular in the description of their boundaries. Scientific novelty and practical significance. The analysis of the types of boundary markers in combination with the available information about the soils of Ukraine shows that when choosing their types do not take into account the properties of the soils of the area through which the boundary of the administrative-territorial unit. As a result, it is not possible to identify boundaries on the ground, which in turn leads to inconsistencies between the authorities and inefficient use of land resources. To solve this problem, it is proposed to use well-developed scientific, technical and regulatory developments on the use of different types of geodetic points, which take into account the depth of freezing and physical and mechanical properties of the soil; the presence of groundwater in places of laying and their chemical state; wetlands and, accordingly, on their basis to offer an expanded range of boundary markers. The proposed types of boundary markers can be used for the boundaries of OTG, districts, cities and areas that run on land.
