DATA DESCRIPTION
ESA is offering, for scientific research and application development, access to Full archive and New Tasking data from WorldView-1 mission upon submission and acceptance of project proposal. These products are available as part of the DigitalGlobe Standard Satellite Imagery products.
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.
