Slovakian Elevation Models
NOTE 2023-08-18: These datasets are currently being integrated into windPRO
Introduction
The Slovakian Digital Terrain Model (DTM) and Slovakian Digital Surface Model (DSM) in windPRO are seamless digital elevation models (DEMs) that covers almost the whole of the Slovakian territory. Source data is released from the "Geodesy, Cartography and Cadastre Authority of the Slovak Republic (ÚGKK SR)" - and is processed, formatted and adapted for use dedicated windPRO use by EMD. The original DTM DEMs are made from multiple regional measurement campaigns using airborne lidar systems (ALS). In windPRO, we deliver the DTM with a 10m grid resolution and the DSM with a 5m grid resolution. More grid-resolutions are available from the ÚGKK SR geoportal.
Dataset Overview
- Spatial Coverage: Slovakia
- Grid Resolutions:
- DTM: 10m
- DSM: 5m
- Data-types: Digital Terrain Model (DTM) and Digital Surface Model (DSM)
- Coordinate system:
- Horizontal: S-JTSK / Krovak East North (EPSG: 5514)
- Vertical: Baltic
- Version: Data downloaded in august 2023. DTM is derived from 'Digital Terrain Model DMR3.5' and DSM derived from "DSM 1.0" from ALS project 1st cycle.
- Vertical Accuracy: N/A
Usage Notes
- For the DSM data, some data are missing in south-eastern part the country (within central Prešovský and Košice regions) - see the map-image to the top-right.
Availability from within WindPRO
The data are available directly from within windPRO in 5-meter and 10-meter grid resolutions for the DSM and the DTM respectively. The data can be accessed from the online-services in the following objects:
- Line Object (with purpose to height contour lines)
- Elevation Grid Object
