Official documentation for citing and acknowledging PGC support (maps, imagery, etc.).
National Science Foundation (PGC’s primary funding source) policy requires researchers to acknowledge NSF support in all publications, web pages, and media interviews.
By accepting PGC’s services, including access to data via the PGC website, users agree to cite PGC and its sponsorship by the NSF. The original source of any third-party data supplied by PGC must also be properly attributed.
Acknowledgement of PGC’s assistance provides PGC with valuable feedback and a measure of its success in the scientific community.
If you have used PGC services, including satellite imagery delivery, follow the guidelines in the “Acknowledging PGC-provided support” section below.
If you have used a map, satellite image or imagery-derived product from PGC in a publication, refer to the “Citing PGC-provided Products” section below.
Please address any questions to your PGC Primary Contact.
Public Release Approval Process for Commercial Imagery
Important! Beyond the required copyright to DigitalGlobe, Inc. and acknowledgement to PGC for support, users of NextView-licensed commercial satellite imagery must request approval prior to releasing or displaying any imagery within publicly-accessible material (academic papers, posters, presentations, etc.).
These citations should be included in the acknowledgements section of any published work, presentation, poster, or document.
