Geodetski in topografski sistem v prostorskem načrtovanju - od geodetskih podlag do koordinate : Geodetic and Topographic System in Spatial Planning - from Geodetic Plans to the Coordinate
Abstract
A system of geodetic data enables administration, management and spatial planning on several levels. For European purposes two datasets, EGM and ERM, have been established, and Slovenia regularly contributes data for its own territory. For the strategic state level, the National General Map at 1: 250,000 has been made in 2005. Regional and inter-regional level is covered by the National Topographic Map at 1: 50,000, completed this year for the entire Slovenia. At the local level, the National Topographic Map at 1: 5000 in the vector form has been established. By now, 40 % of the Slovenian territory, mostly of urban areas, has been covered. The geodetic branch provides many other topographic and real estate data for local spatial planning, thus the contribution of geodesists in terms of knowledge in data preparation and cartographic representations is valuable. Detailed Plans are based on Geodetic Plans, which have become, after the recent adoption of regulations, an important part of geodetic service. In field measurements surveyors are supported by the national network of GPS reference stations called SIGNAL. Unfortunately, all spatial data in Slovenia are still inaccurate due to the deformations in the existing national coordinate system; a solution will be provided with the introduction of the European Terrestrial and Vertical Reference Systems.
