USER NOTES:

Some points fall outside of the district 7, District 8 area. If the typographical error could be verified (such as if a series of aids in sequential order with the same name were all at 83 W longitude and one within the series had the typo 38 W longitude), then it was corrected. If the typo was not obvious the placement of the aid was left alone. For FGDL purposes these points were removed.

Aids without coordinates have been removed. Otherwise this data set is complete as the source data provided by the Coast Guard.

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

Prior to July 1, 2004, the Fish and Wildlife Research Institute (FWRI) was known as the Florida Marine Research Institute (FMRI). The institute name has not been changed in historical data sets or references to work completed by the Florida Marine Research Institute. The institute name has been changed in references to ongoing research, new research, and contact information.

This data set represents a GIS layer of ATONs as of December 2008, with spatial extent of the Seventh Coast Guard District plus Sector Mobile from the Eighth Coast Guard District. These data are not to be used for navigation or positional referencing. Users are instructed to consult the appropriate navigational chart, notice to mariners, and light list for any purpose other than natural resource conservation planning. Due to the possibility of unknown errors in reporting, projection or datums the accuracy of these data are not certified. The existence, position and description of features might have changed since data were originally compiled in 2008.

FWRI has not attempted to verify horizontal positional accuracy, but typographical errors may exist in the source data.

This data is provided 'as is' and its vertical positional accuracy has not been verified by GeoPlan

Acknowledgement of the FWC-FWRI (Florida Fish and Wildlife Conservation Commission-Fish and Wildlife Research Institute) as the data source would be appreciated in any products developed from these data, and such acknowledgment as is standard for citation and legal practices for data source is expected by users of this data. Please cite the original metadata when using portions of the record to create a similar record of slightly altered data, such as reprojection. If any data are modified or adjusted, please share the edited information with FWC. Users should be aware that comparison with other data sets for the same area from other time periods may be inaccurate due to inconsistencies resulting from changes in mapping conventions, data collection, and computer processes over time.

This is not a survey data set and should not be utilized as such. These data are not to be used for navigation.

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.

DATA LINEAGE SUMMARY:

The source data were received as Excel Spreadsheets from the Coast Guard. FWRI reformatted the latitude and longitude to decimal degrees in order to convert to shapefile using the Add X,Y tool in ArcMap. FWRI also added additional attributes based on the information provided by the coast guard. See the Entity and Attribute Section for more information. Process Date: 200901 GeoPlan received this data in shapefile format via FTP from FWRI on July 7, 2009. When received, the data was in Geographic projection Albers NAD 83, Spheroid: GRS 80. The file was projected to FGDL Albers HARN. The shapefile received had 16545 records some of which fell outside the FGDL extent. The records that fell within the FGDL extent were selected out and exported to a new shapefile. Two points were deleted that fell outside of the districts. These points were Puerto De Tierra Pier 14 East Dock Light and NOAA Data Lighted Buoy 41043. Therefore this data set does not represent all aids to navigation for the Seventh and Eighth Coast Guard Districts. The final FGDL data set has 15947 records. For a complete Seventh and Eighth USCG District data set visit the FWRI site at: http://ocean.floridamarine.org/mrgis_ims/Description_Layers_Marine.htm - Reprojected data to FGDL Albers HPGN - Changed DESCRIPT field to AID_DESC - Added a DESCRIPT field to attribute table based on AID_NAME - Added a FGDLAQDATE field based on date received from source - Renamed shapefile from atons_uscg_point to cgaton_jan09 - Upcased all records in the table Process Date: 200907009 Data imported to ArcSDE and exported as a shapefile.
