How to cite and acknowledge PGC services (maps, imagery, etc.) in publications or academic journals.
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 Acknowledgements section below.
If you have used a map, satellite image or imagery-derived product from PGC in a figure, refer to the Figure Citations guidelines.
Please address any questions to your PGC Primary Contact.
