2008 impervious data was provided to Sanborn by Queen Anne County. Sanborn updated impervious features using 0.5' GSD 2016 orthophotography provided by the State of Maryland.
Using ArcGIS, edits to the 2008 impervious data were made to account for changes on the ground, as interpreted in the 2016 orthophotography. Once edits were complete, reviews for completeness and consistency were completed for the entire AOI based on visual interpretation of the 2016 orthophotography. Then, any necessary revisions were made to correct errors. Upon acceptence of revisions, topology was validated. Then, a review was made for completeness, and data was published.
