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.

Other divisions within the FDEP have felt the need to develop digital coverages for the State-owned or managed properties they oversee and are in the process of reducing the legal descriptions on deeds into a digital form by interpreting and transferring the legal description to a quad sheet or using one or another of the COGO (COordinate GeOmetry) systems. These lands include the Aquatic Preserves and the State Park boundaries. Where possible, to minimize duplication of effort, the Division of Environmental Permitting either acquired the boundaries already created for the Aquatic Preserves, or entered into a joint venture to create boundaries for the 145 lands managed by the Division of Parks and Recreation.
All other categories are taken from the Lands managed for Conservation created and compiled by GEOPLAN or have been created by us using descriptions from the Outstanding Florida Waters documentation. Those boundaries created internally were scanned from published materials, registered and rectified with 1:24,000 USGS Public Land Survey section corners. Data was then extracted from USGS 1:24,000 hydrology layer and attributed. For boundaries not completely represented by USGS 1:24,000 hydrology layer, arcs were digitized directly from the scanned material to complete the boundary.
The COGO method has several advantages and disadvantages for use in producing a database for the OFWs. It uses primary source material - the legal description on the deed. Data created using this method should have validity within the legal system because it is from a source familiar to the courts. Other agencies are using the COGO system so it is a familiar process and product. COGO methodology is appropriate in that it weds the new system for describing land ownership to the existing system. Additionally, each parcel boundary will be maintained in a digital form and can be extracted from the official boundary as a parcel's status changes. This data layer will also be maintained and updated by the stewards of all the state park boundaries data, so as the parcel boundaries change, the OFW boundaries will automatically be updated. The downside is that COGO (or the survey data it automates) is labor intensive and requires extensive training and expertise to use. Each legal description references source materials that may only be available locally or from the county appraiser's office, at a cost of travel and materials. Each park boundary may have numerous parcels transferred to the state at different times and some parcel boundaries overlap.
