Each point in this GIS data set represents a single deployment event (either a uniquely located artificial reef or deployments of the same reef on different days). Division of Marine Fisheries Management maintains and updates the source database. This data set represents deployments through March, 2011.
This data set is for display purposes only. Do not use it for navigation. Each point location is intended to represent a single deployment event, defined as either different location coordinates or the same coordinates but on different days. It is important to note that DMF has not independently confirmed most of the reef locations and this data had been supplied form various sources without verification.
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. These data are also known as "Florida Artificial Reef Deployment Database." Note: if these data are converted to shapefile, null values in number fields will be converted to zero. This will hide any true zero values.

GeoPlan relied on the integrity of the attribute information within the original data.
FWC-DMF has not independently confirmed most of the reef locations, and this data had been supplied from various sources without verification.
Two deployment locations did not have latitude and longitude coordinates in the spreadsheet, so those deployments are not represented in the GIS data. Items of incorrect data type for the fields (such as text data in a date field) were not converted. If an item is questionable, see the original source file from DMF.
Original coordinates were in decimal minutes with 1/1000 minute precision (xx.xxx minutes), but data have not been verified or field checked by DMF or FWRI.
This data is provided 'as is' and its vertical positional accuracy has not been verified by GeoPlan
Spatial and Attribute Information
The data were acquired as an Excel spreadsheet from the DMF. Some data fields contained numbers formatted as text or other field inconsistencies. These were corrected when possible. This spreadsheet was then imported in to Access and the coordinates in decimal degrees were converted to a personal geodatabase feature class using the "Add X,Y" function in ArcMap 9.1. This feature class was reprojected to FWRI Albers and loaded into ArcSDE.

GeoPlan received this dataset from the Fish and Wildlife Research Institute (FWRI) via FTP on 07/13/2011. The data was received as a shapefile in projection: Albers, NAD 83, GRS 80. The dataset was then projected from NAD 83 to FGDL Albers HPGN. - Reprojected data to FGDL Albers HPGN - Added a DESCRIPT field to attribute table based on REEFNAME - Added a FGDLAQDATE field based on date of download from source - Renamed file from artificialreef_fl_point to artref_mar11
Internal feature number.
ESRI
Feature geometry.
ESRI
This is a unique number associated with each deployment record. It begins with the first two letters of the county name and a four digit numerical code assigned at the time this new field was developed in July of 2005. New deployments will be assigned sequential codes within the county and this ID number will not change.
DMF
This field is intended to identify one set of coordinates within a patch reef that can be used as a central identifier for each reef. All other deployments within that reef will be labeled "PATCH" reefs. This field is intended to be used to sort for the number of reef sites, not the larger number of reef deployments. This field has not yet been populated as of March 5, 2007 (it defaults to "CENTER" and once populated the DEPLOYNUM field will be deleted.)
DMF
The Florida county nearest to the artificial reef project.
DMF
The FWC-DMF contract number, if the reef is a grant-funded deployment administered by DMF; if not, this field is blank.
DMF
Federal Aid in Sport Fish Restoration Program grant number, if the project was funded by that source; if not, this field is blank.
DMF
The recipient of the DMF or Federal grant; it may be other than the county, such as cities, non-profit organizations or universities.
DMF
Amount (in dollars) of the reef project regardless of who funded it. This should be a total of LOCAL and FWC amounts.
DMF
Amount (in dollars) of the reef project funded by local sources
DMF
Amount in (dollars) of the reef project funded by DMF or Federal grants. In cases where multiple deployments were funded with the same grant, the amount may not have made it into the final file for all deployments since text values were used to indicate where this information was recorded. Contact DMF for the original spreadsheet if this information is needed.
DMF
The date the materials were placed offshore, if known. If only the year is known, then the last day of the year is entered (example 1988 would be 12/31/88). If only a month and year is known, then the last day of that month is entered (example July 1998 would be 7/31/98). 1/1/1900 is used if the deployment date is unknown.
DMF
The common name for the reef site. This may or may not be the name of the permitted site as several reefs may be within one permitted site. If a site is located within a shallow protected area, the word (BAY) is entered in parenthesis after the name. If the reef was unintentionally sunk offshore during a storm event or during war, the site is considered a wreck and a (W) if placed beside the name.
DMF

DMF
The most recent date that DMF divers visited the site; data are given in month/day/year format. This would be updated after the dive event and the previous dive date shifted to the field "PREDIVE1" if applicable.
DMF
This field is a code to indicate which sets of coordinates available to DMF are presumed to be the most accurate, the latitude and longitude or LORAN. It represents how these more accurate coordinates were generated, if known. If blank, it is unknown how these coordinates were generated and which sets are most accurate. LORAN is assumed to be more accurate prior to about 1995. DMF staff used ASF corrections from the 1984 Defense Mapping Agency tables to mathematically calculate most of the non-field generated coordinates using the Andren Software LoranGPS program. Please note that all coordinates used to create the shapefile were the latitude and longitude coordinates.
DMF
these lat/longs were taken with a WAAS unit on the reef
DMF
these latitude and longitude coordinates were taken with a DGPS unit on the reef
DMF
these latitude and longitude coordinates were taken with a non-differential GPS unit on the reef
DMF
these LORAN coordinates were taken by LORAN unit on the reef
DMF
Both sets of coordinates were given to DMF
DMF
The second most recent date that DMF divers visited the site; data are given in month/day/year format.
DMF
The third most recent date that DMF divers visited the site; data are given in month/day/year format.
DMF
The number of discrete reef set, if greater than 1 then it is effectively the same site as above. A sort for "1" should return allow discrete reef sites (This field will soon be deleted in favor of multiple deployment date fields).

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. For more information regarding scale and accuracy, see our webpage at: http://geoplan.ufl.edu/education.html
