Romania Elevation Model

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

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

Different Grid Resolutions of the Original Romanian Source DTM (5m, 10m and 26.5m).

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. So the current Digital Terrain Model (DTM) holds a precision that matches the detail found in the original contours. The initial DTM 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 modelling. This resampling is based on the highest resolution data and a bi-linear interpolation method. The data provided by EMD reflects its status as of June 2024.

Usage Notes

• The original source data came in different grid-resolutions for regions/counties (Judet) - see the map to the right.
• The original source data does not include part of the Danube delta (to the east in Tulcea and north-east Constanta counties). See the map to the top-right.
• The license conditions (in Romanian language) is available in a pdf - HERE
