Highlights from Living Planet Symposium

As remote sensing scientists and data-users from around the world converged at the Living Planet Symposium (LPS) in Bonn recently, a common thread was evident in many scientific sessions and meetings – the right environmental data can accelerate our understanding of the rapid changes in Earth’s system.

VHR Data Quality in the limelight

In recent years, the satellite landscape has steadily expanded with a variety of very high resolution (VHR) commercial satellites, also emerging from new space providers. A result of this growth is an increased need to address data quality assurance.

About WorldView-1

WorldView-1 is an environment-monitoring satellite from Maxar of the United States which launched on 18 September 2007 and remains operational.

It became the world's first 50 cm resolution commercial imaging satellite.

DATA COLLECTIONS

These collections are available as part of the Maxar Standard Satellite Imagery products and are distributed by European Space Imaging (EUSI).

ESA will support as many high-quality and innovative projects as possible within the quota limit available, therefore only a limited amount of products can be made available to each project.
