Spatial data in urban planning

Abstract

In the view of the sections of the state information system for ensuring urban planning activities, the place is shown and the role in regulating the development of territories is revealed. The composition of spatial data contained in various types and sections of urban planning documentation is analyzed. A review of world practice has shown that many of the analyzed spatial data are included in national spatial data infrastructures, which indicates their high level of signifi cance. Consideration of the issues of updating graphic documents by maintaining duty plans of urban planning information using GIS technologies revealed the need to consolidate secondary (updated) documents at the legislative level. An analysis of the requirements for spatial data in the fi eld of urban planning and the real estate cadastre showed the need for their refi nement in terms of clarifying the requirements for the accuracy of describing the objects of urban planning activities and unifying the coordinate systems used. Proposals are given for the establishment of uniform requirements for methods for determining the coordinates of spatial objects and the rules for determining the permissible discrepancy, as well as requirements for the accuracy of determining the coordinates of the characteristic points of the boundaries of objects of urban planning activities.

“…As a result of constant integration, there is a pressing need for high-precision geospatial support for a whole range of tasks in the field of geodesy, cartography, construction, cadastre and many others [4][5][6]. At the same time, obtaining reliable high-precision geospatial data is directly related to the level of their metrological service.…”
