GeoPlan relied on the integrity of the attribute information within the original data. |
Inconsistencies between the original locations of transmission lines were detected and corrected by overlaying the downloaded shapefile with a 1999 doqq file for the State of Florida. |
A note concerning data scale: Scale is an important factor in data usage. Certain scale datasetsare 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. 1:250000 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 sectionand the Data Source Contact section of this documentation.

1999 FLORIDA DOQQ THINKBURST MEDIA, INC. http://data.geocomm.com/catalog/US/61093/group111.htm |
This data layer was downloaded from Thinkburst Media, Inc at http://data.geocomm.com/catalog/US/61093/group111.htm. When downloaded, the layer was an E00 interchange file, and GeoPlan converted it to an ArcInfo coverage. The data layer was then converted into a shapefile and projected from North American Datum 1983 to FGDL HPGN and overlaid on a 1999 doqq file for the State of Florida. Discrepancies between the placement of power transmission lines in the shapefile and the location of power transmission lines on the 1999 doqq file were remedied by aligning the features in the shapefile with the power transmission lines on the 1999 doqq file at a scale of 1:24,000. Process Date: 20051200 GeoPlan, during the QA/QC process included the following aspects: -added [EDIT_TYPE] field based on whether the line was "moved" or "created," or whether the location of the line on the doqq was undetectable, or "N/A." -added [DESCRIPT] field based on [UTLNTYPE] and information provided by source. -added [FGDLAQDATE] field based on the date FGDL acquired the data from the source. Process Date: 20060100 |
