DDate2	The data of deployment (YYYYMMDD).
Deployment	The common name for the deployment site.
Descriptio	Brief text description of artificial reef.
Primary_Ma	The type of reef material that makes up the majority of the deployment, prefixed by six general categories (CONCRETE, METAL, MODULE, OTHER, ROCK, and VESSEL). Pre-fabricated reef modules and marine vessels are labelled as MODULE or VESSEL regardless of material composition. All marine vessels have a metal hull unless otherwise noted in this field. The quantity of materials from the original deployment is indicated in parenthesis if known.
Tons	Dry weight of the reef material. Use this field to judge the approximate overall size of the reef.
Relief	Height (in feet) of the reef materials off the bottom.

USER NOTES:

FWC-DMF has not independently confirmed most of the reef locations, and this data had been supplied from various sources without verification.

The data appear to be complete, as of the delivery date from DMFM to FWRI (6/26/2017).

Please note that reef materials can move, degrade, or become buried over time. This is especially true for metal materials with thicknesses less than 1/4 or lightweight materials. Additionally, many reef locations in the database are based on historical data with inherent potential location inaccuracies that may not have been ground truth since their deployment. If you have updated information regarding the condition or location of an artificial reef please contact the FWC Artificial Reef Database Administrator via email at bradley.ennis@myfwc.com.

Additionally, many reef locations in the database are based on historical data with inherent potential location inaccuracies that may not have been ground truth since their deployment. If you have updated information regarding the condition or location of an artificial reef please contact the FWC Artificial Reef Database Administrator via email at bradley.ennis@myfwc.com 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.

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.

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. Please note that reef materials can move, degrade, or become buried over time. This is especially true for metal materials with thicknesses less than 1/4 or lightweight materials. Additionally, many reef locations in the database are based on historical data with inherent potential location inaccuracies that may not have been ground-truth since their deployment. If you have updated information regarding the condition or location of an artificial reef please contact the FWC Artificial Reef Database Administrator via email at bradley.ennis@myfwc.com

The vertical accuracy is accurate as of the time of deployment.

Acknowledgement of the FWC-FWRI (Florida Fish and Wildlife Conservation Commission-Fish and Wildlife Research Institute) as the data source, and the originator FWC Division of Marine Fisheries, 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.

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:

DMF provided the data to FWRI as a feature class projected in WGS84. FWRI reprojected the data into NAD83_(2011)_FGDL_Albers (meters) and wrote metadata for the dataset and imported the data into the SDE databases. Process Date: 20170621 This dataset was downloaded by the GeoPlan Center on 10/26/2017 from the FFWCC website (http://geodata.myfwc.com/datasets/artificial-reefs-in-florida). The data was received as a shapefile and was in the following projection: GCS_WGS_1984. The data was projected to NAD83 HARN using the WGS_1984_(ITRF00)_To_NAD_1983 + NAD_1983_To_HARN_Florida transformation. This is the first time we've received this dataset in WGS84. Previously it came in a custom PCS Albers projection. Projecting from WGS84 to NAD83 HARN has introduced a shift of approximately 1 meter. - Added the field DESCRIPT based on DEPLOYMENT. - Added the field FGDLAQDATE based on date downloaded from source. - Upcased all text in the attribute table. - Data set was renamed artref_jun17 from ArtificialReef_fl_point. Process Date: 20171026 Dataset copied. Process Date: 20171103
