Refer to Contract specifications between NRCS and SFWMD. Tim Scharff was Contract Administrator. |
The dataset is still missing some annotation on the Secondary and Tertiary canals. Vicky LaBelle was working on this but left the District in 1997/1998. |
GeoPlan relied on the integrity of the attribute information within the original data. |
|
To depict the canals in South Florida that are under the jurisdiction of the South Florida Water Management District. |

The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist. Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. The University of Florida GeoPlan Center shall not be liable for any damages suffered as a result of using, modifying, contributing or distributing the materials. A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling 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. 1:125000 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 analysis. 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.

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.
