Map of Florida showing progress of high resolution NHD photo revision in Florida.

  • 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.
