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 windPRO 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.

Slovakian Digital Terrain Model (DTM) - 10m grid resolution.
Slovakian Digital Surface Model (DSM) - 5m grid resolution.

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 dedicated windPRO use by EMD. The original DEMs are made from multiple regional measurement campaigns using airborne lidar scanning 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 (in windPRO):
    • DTM: 10m (down-to 5m in ÚGKK SR source data)
    • DSM: 5m (down-to 1m in ÚGKK SR source data)
  • 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

  • Available in windPRO version 4.0+: This dataset is available from windPRO version 4.0 (from build #416). This is due to the coordinate-system being used in the data-source; this was added in 4.0. So, in order to use this dataset, the project must be created in windpro 4.0+ - and unfortunately this dataset is not available in earlier versions of windPRO.
  • Missing DSM data: 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
