USER NOTES:

GeoPlan relied on the integrity of the attribute information within the original data layer

A note concerning data scale: Scale is an important factor in data usage. Certain scale datasets are not suitablefor some project, analysis, or modelling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:250000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analyses. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation. For more information regarding scale and accuracy, see our web pages at: http://www.geoplan.ufl.edu/education.html

FGDL QUALITY ASSURANCE STATUS:

A contract was initiated between the SFWMD and the NRCS (Soil Conservation Service) in 1997. Tim Scharff was the contract administrator. NRCS personnel digitized SFWMD canals to match 1mm DOQQs. The lines were attributed PRIMARY, SECONDARY or TERTIARY as well as MAJOR or MINOR. Tim Scharff QA/QC'd the Primary canals, but had Vicky LaBelle working on attributing the secondary and tertiary canals. Vicky left the District sometime in 1998 or 1999 and no one else continued on in her place. However, all the Primary canals were pulled out from this database and became the new "SFWMD Canals" layer. In 2003, GeoPlan received this data in shapefile format via email from South Florida Water Management District (SFWMD). The dataset was projected to FGDL Albers HPGN. When received, the data was in StatePlane Florida East (FIPS 0901) NAD_1983 Feet. -Reprojected to FGDL Albers HPGN -Dropped old internal coverage items: fnode_, tnode_, lpoly_, roply_, cover# and cover id -Converted length from feet to meters -Added DESCRIPT field based on NAME to attribute table -Renamed file from HYSURCRC to SFWMD_CANALS
