The photography for the DOQs upon which this layer is based was flown by the National Aerial Photography Program (NAPP) from Jan 1994 through Dec 1995 with the bulk of photos taken in 1994. See the item DOQ95_INFO in the attribute table of gislib.img_idx_doqs for specific photo dates.
An online Data User Guide is available (GISDOC, Data, Data User Guides). It contains information about completed quality assurance efforts, known problems with the data layer, and plans to update and improve the data.
To create the data, the orthorectified images were displayed on a computer screen at varying scales of about 1:12,000 or less.
1. Added an item REV to the attribute table identifying polygons that were revised. A value of A indicates an attribute change only (LUCODE or LUCODE2); no arcs were revised.
2. Submerged aquatic vegetation: Moved submerged aquatic vegetation codes (6450) to LUCODE2 and populated LUCODE with the appropriate waterbody code.
3. Indian River Lagoon basin: Changed estuaries miscoded river (5100) to estuary (5400).
4. Lakes and Reservoirs: Many lakes were coded as reservoirs, and some reservoirs were coded as lakes. These were revised appropriately.
5. Commercial and Services: Collapsed all 1400 level 3 codes other than 1460 and 1480 into 1400.
6. Extractive: Revised codes 1650-1670 to be consistent with FLUCCS and the rest of the state.
7. Fixed miscellaneous erroneously coded polygons.
A complete and detailed listing of the changes is available upon request, as well as summary files listing the frequency and total area of each land use class before and after the revisions.
For those outside the SJRWMD, the PI Key has been added to the GIS export library on CD#6. The files can also be accessed with a web browser on the SJRWMD web site: www.sjrwmd.com. Follow the links to Data, Geographic Information Systems, Download GIS Data; then locate the 1995 Land Use / Land cover entry in the table, select the download link, and select the lu95_pi_key link. The file keylist.html is the master file from which users can link to all the land use codes.
