Coordinate basis adaptation of cataloging of unified immovable complexes included into the Russian-Chinese initiative project “One Belt – One Way” (by example railway transport)

Coordinate support is a fundamental basis to study the characteristics of objects and phenomena which occur in the surrounding space. Parameterization of the characteristics is impossible if the rules for describing objects either within themselves or concerning their topological properties are not established. The rules for the metric description of the terrain objects at the level of general state geodetic and cartographic support tasks are determined. Nevertheless, there are quite important tasks to describe some elements of the sets for which the established rules are not considered as optimal, so it will be a more efficient solution to switch to alternative parameters of metric systems. Such objects include linear objects (such as real estate, buildings, natural objects) on the Earth’s surface which are characterized by a significant accumulation of errors in their description in the established coordinate systems (projections). If considered applied, there is some certain necessity to determine (calculate) the optimal rules (parameters) in a number of cases in order to form the metric system of their description for the design and departmental cataloging.
