SPACEWHALE

SPACEWHALE is a service providing AI-based detection of large whales in very high-resolution satellite imagery. The method allows monitoring remote and unexplored regions in the high seas, where traditional boat or aerial-based surveys are difficult to execute or even impossible.

Mapping whales from space


SPACEWHALE uses a semi-automated process to evaluate satellite imagery, combining state-of-the-art artificial intelligence and manual verification by a team of marine mammal experts.

  • In a first step, the SPACEWHALE algorithm scans the satellite imagery for the presence of whales.
  • In the second step, our experts review the detected objects to verify the classification and identify the species.

Using this approach, areas with no whales are excluded by the algorithm and large, inaccessible survey areas can be processed in a relatively short time. Several studies document the accuracy of this method (Borowicz et al. (2019), Höschle et al. (2022)).

SPACEWHALE processes the very high-resolution imagery immediately and the results are quickly made available for the client. The client receives sections of the imagery including the detected marine mammals, tables indicating the abundance as well as maps showing the distribution of the animals. Experts from industry, government and nature conservation can use these data in baseline studies and environmental impact assessments.

Our services in detail


Abundance estimates

We provide abundance estimates for large whales or wildlife species on a per-survey basis which can be used to generate population trends over time.

Distribution maps

Using advanced modelling techniques, we create distribution maps of target species in ESRI-compatible raster formats.

Bespoke analyses

In cooperation with our clients we offer bespoke analyses to help guide conservation and advanced ecological studies.
