Development of the National Altitude Transformation Model between SVS2000/Trieste and SVS2010/Koper (ŠTUDIJA)

In Slovenia, at the end of 2018 (Decree determining the parameters of the vertical part of the vertical component of the national spatial coordinate system, 2018) we moved to a new elevation system with the designation SVS2010 (EPSG 8690) with an elevation date of 2010 (Koper), which replaces the old elevation system with the designation SVS2000 (EPSG 5779) with an elevation date of 2000 (Trieste). The study developed a single elevation transformation model for the territory of Slovenia, consisting of the elevation transformation surface - SLO-VTP2024, the elevation transformation programme - ViTra and the surface to assess the accuracy of the elevation transformation surface. The elevation transformation model will allow different spatial data managers to easily transition from the old to the new elevation system.
