Frequent Questions

What resources should I contribute to the EDG?

EPA requires that metadata for geospatial assets produced or improved by EPA personnel and/or EPA contractor staff be contributed to the EDG. The term “improved” refers to any type of value-add process that alters the data set or resource from its original form.  Metadata records that describe resources that would benefit other EPA organizations are encouraged but not required for contribution. You may also optionally contribute non-geospatial metadata.
