Bremen Elevation Models

Note (2025-04-04): This dataset is currently being integrated into windPRO.

Elevation Model for Bremen and Bremerhaven - 1m grid resolution.

Introduction

The digital elevation models for Bremen and Bremerhaven, Germany, available in windPRO, are derived from open geodata provided by the Landesamt Geoinformation Bremen. These models offer three grid resolutions (1m, 5m, 20m) to cater to different needs, ranging from photomontage modelling to wind farm analyses. The data, updated as of April 2025, ensures accuracy and relevance. The dataset in windPRO has been amended with an additional buffer-zone of 10km around the cities of Bremen and Bremerhaven. The data from this buffer zone comes from the Niedersachsen dataset, also available in windPRO, see here.

Dataset Overview

• Spatial Coverage: Bremen and Bremerhaven, Germany - including a buffer zone of 10km
• Resolution: 1m, 5m & 20m (in windPRO, with original data in 1m resolution)
• Data-type: Digital Terrain Model (DTM)
• Coordinate system
  • ETRS89/UTM32 (EPSG 25832)
  • Vertical: N/A
• Version:
  • Data originates from year 2015 (Bremerhaven) and 2017 (Bremen).
  • Data was downloaded in 2025.
• Accuracy:
  • Vertical: 0.1-0.2m (in original 1m data). However, it will likely be larger in areas with forest, industry, at settlements or steep-slopes.
  • Horizontal: N/A

Availability from within WindPRO

The data are available directly from within windPRO in 3 different grid resolutions. The data can be accessed from the online-services in the following objects:
