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
