Romania Elevation Model

2024-07-02: This dataset is currently being integrated in windPRO.

Seamless Mosaic of the Romanian DTM (elevations in meters).

Introduction

The National Agency for Cadastre and Land Registration in Romania, known as ANCPI (Agenția Națională de Cadastru și Publicitate Imobiliară), has made available the Romania Elevation Model, a digital terrain model (DTM). The creation of the model was conducted using contour lines with a 1:50,000 scale. The contours derive from the 1995 Romanian Topographic Map, though certain regions have been enhanced with newer information collected through to 2019. The original topographic maps present contour intervals of 10 meters in level terrain and 10-20 meters in hilly areas, with a precision that matches the detail found in the existing Digital Terrain Model. The initial model is offered at different grid resolutions depending on the area; the most widely accessible are the 5m and 10m resolutions. In windPRO, we provide two versions of the model at 5m and 20m resolutions, both resampled by EMD to ensure the data is suitable for use in broader scopes required for wind farm analysis and wind flow modeling. This resampling uses the highest resolution data and a bi-linear interpolation method. The data provided by EMD reflects its status as of June 2024.

Dataset Overview

• Spatial Coverage: Romania
• Resolution: 5m and 20 m in windPRO
  (original data in 5.0m, 10.0m and 26.5m grid resolution either as geotiff or arcgis grid-format, see usage notes below)
• Data-type: Digital Terrain Model (DTM)
• Coordinate systems:
  • Horizontal: Pulkovo 1942(58) / Stereo70 (EPSG: 3844)
• Version: This dataset reflect the data-status of June 2024.
• Accuracy: (stated by ANCPI)
  • 10m for mountaneous areas
  • 5m for hilly areas
  • 1.5m for flat areas

Usage Notes

• Please be patient when downloading data from this model - it may take some minutes for our servers to compile the data for you (especially for the 1m and 5m models). This is due to the high-resolution and size of the model - with about 1.4Tb of elevation data records in 64000 indivudual data-tiles. If this is an issue for you, please consider to use smaller areas with high-resolution data (1m, 5m)- and larger areas with 20m resolution data.
• A few - about 20 - tiles in a narrow strip approximately 1.5 km from the eastern boarder did not hold data at the 1m grid resolution. These (few) tiles have not been included in this mosaic model from EMD.
• Since the data-source contains campaigns from multiple years, generally, data from the most recent year has been used in windPRO. In the case of issues/problems with the most recent data-source, it was replaced with older data.
• Due to missing data, five 2x2km tiles to the north of the city of Szczytno was taken from the PL-EVRF2007-NH model. These tiles had their vertical reference changed to match that of this DTM-mosaic (vertical correction was in the order of 0.3m).
• If you find issues/problems/missing-data within this dataset, feel free to contact our data custodian - Morten Lybech Thøgersen (mlt@emd.dk), with the nature of the issue and the location (geographical coordinates).

Availability from within windPRO

The data are available directly from within windPRO as 5m and 20-meter grid resolutions. The data can be accessed from the online-services in the following objects:

• Line Object (with purpose to height contour lines)
