The Florida NHD revision program consists of a project
manager, QA/QC manager and three editors.
Full photo revision yields approximately 150 square miles
per month of updated data per editor.
Prioritization of sub basin editing is derived from date of
original USGS 24K DLG quadrangle data, TMDL/WBID requests for
updates, contractual agreements, requests from county/regional
government and requests for miscellaneous revisions.
