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

  • The Florida NHD stewardship program consists of a project manager, NHD Steward/Technical Lead, QA/QC manager/editor and two additional full time 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.
  • Florida DEP provides the statewide NHD to end users through Map Direct, DataMiner, and the FDEP Geospatial Open Data Portal.
  • The data provided was last updated in December, 2015 and represents a snapshot of the NHD as of 10/22/2015.
