FEATURE ATTRIBUTE TABLES CODES AND VALUES:

Item
Item Description
OBJECTID Internal feature number.

COAST This field indicates whether the reef is in the Gulf of Mexico "G" or Atlantic Ocean "A."
A = Atlantic Ocean

G = Gulf of Mexico


COE_PERMIT This is the Corps of Engineers active permit number for the site at the time of deployment.

CONTRACT The FWC-DMF contract number, if the reef is a grant-funded deployment administered by DMF; if not, this field is blank.

COUNTY The Florida county nearest to the artificial reef project.

DEPLOY This is a "yes" or "no" field that indicates whether FWC-DMF staff were present for the deployment of the materials.

DEPLOYDATE 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). If the deployment date is unknown this field is blank.

GRANTEE_SP The recipient of the DMF or Federal grant; it may be other than the county, such as cities, non-profit organizations or universities.

DEPTH Depth (in feet) to the bottom at the time of deployment.

DESCRIPTIO This field contains a brief narrative description of the deployment and the name of the ship if available.

DIVE_DATE 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.

FEDGRANT Federal Aid in Sport Fish Restoration Program grant number, if the project was funded by that source; if not, this field is blank.

FT_PRNT_FT Footprint of the reef materials on the bottom in square feet.

GPS 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. Values are; WAAS: these lat/longs were taken with a WAAS unit on the reef, DGPS: these latitude and longitude coordinates were taken with a DGPS unit on the reef, GPS: these latitude and longitude coordinates were taken with a non-differential GPS unit on the reef, LOR: these LORAN coordinates were taken by LORAN unit on the reef, BOTH: Both sets of coordinates were given to DMF 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.
DGPS = these latitude and longitude coordinates were taken with a DGPS unit on the reef

GPS = these latitude and longitude coordinates were taken with a non-differential GPS unit on the reef

LOR = these LORAN coordinates were taken by LORAN unit on the reef

BOTH = Both sets of coordinates were given to DMF

<null> = If blank, it is unknown how these coordinates were generated

WAAS = These lat/longs were taken with a WAAS  unit on the reef.


ID 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.

LAT_DD Latitude coordinate in decimal degrees

LATITUDE North latitude in degrees, decimal minutes (DDMM.MMM)

LON_DD Longitude coordinate in decimal degrees.

LONGITUDE West longitude in degrees, decimal minutes (DDMM.MMM)

LORAN1 The first set of LORAN time delay coordinates for the reef.

LORAN2 The second set of LORAN time delay coordinates for the reef.

MATERIAL1 The type of reef material that makes up the majority of that deployment. If it is a ship or barge, the size is given in feet (125'), if known. If the material is a prefabricated modular unit, the number of units is given in parentheses, (i.e. Reefballs (80)).

MATERIAL2 The second type of reef materials placed on the reef during that deployment.

MATERIAL3 The third type of reef materials placed on the reef during that deployment.

PERMIT_SIT The common name for the permit site as it appears on the Corps of Engineers permits.

PREDIVE1 The second most recent date that DMF divers visited the site; data are given in month/day/year format.

PREDIVE2 The third most recent date that DMF divers visited the site; data are given in month/day/year format.

PREDIVE3 The fourth most recent date that DMF divers visited the site; data are given in month/day/year format.

PREDIVE4 The fifth most recent date that DMF divers visited the site; data are given in month/day/year format.

REEF_SET 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.)

REEFNAME 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.

RELIEF The height (in feet) of the reef materials off the bottom, also known as profile.

SHAPE Feature geometry

DEPLOYMUN 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).

SOURCE Where the current sets of coordinates were originally obtained. (1) MPF, the FWC Materials Placement Forms, (Required by Chapter 370.25, Florida Statutes) (2) Dive date was an FWC field visit, (3) Pybase 97 was the Atlas of Artificial Reefs by Florida Sea grant 1997 (most of the records with blank values in this field also came from this source). (4) Various monitoring grants to field truth locations or county staff.
1 = MPF, the FWC Materials Placement Forms, (Required by Chapter 370.25, Florida Statutes

2 = Dive date was an FWC field visit

3 = Pybase 97 was the Atlas of Artificial Reefs by Florida Sea grant 1997 (most of the records with blank values in this field also came from this source).

4 = Various monitoring grants to field truth locations or county staff.


TONS The dry weight (in US tons) of the reef material deployed, if known.

TYPE This is special type of reef that may be tracked, currently three types (1) WRECK (not intentionally placed), (2) BAY (inshore Bay waters) and (3) MITIGATION (reefs placed for mitigation purposes).
1 = WRECK (not intentionally placed)

2 = BAY (inshore Bay waters)

3 = MITIGATION (reefs placed for mitigation purposes)


VOL_DIVE Dates that any non-FWC official dives were done on site.

VOLUMEFT3 Volume of reef material in cubic feet, if known.

JURISDICTI Jurisdiction

VOLUMEYD3 Volume of reef materials in cubic yards, if known.

DESCRIPT FGDL added field based on REEFNAME

FGDLAQDATE FGDL added field based on date downloaded from source

AUTOID Unique ID added by GeoPlan


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

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

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.

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:

DATA LINEAGE SUMMARY:
The data were acquired as an Excel spreadsheet from the DMF. Some 
data fields contained numbers formatted as text or other field inconsistencies. 
FWRI staff formatted to match existing field types. Some information incompatible 
with existing field types was lost. Dollar value fields associated with individual 
grants were removed for this public GIS dataset, for original source spreadsheet 
information please contact DMF. 

This spreadsheet converted to a shapefile feature class using the "Add X,Y" 
function in ArcMap. This feature class was reprojected to FWRI Albers and 
loaded into ArcSDE.
Process Date: 2014062714

GeoPlan received this dataset from the Fish and Wildlife Research Institute (FWRI) via FTP on 7/1/2014. The data was received as a shapefile in projection: Albers NAD 83. The dataset was then projected from Albers 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_2014_public to artref_apr14 - Deleted 1 record with no spatial information Process Date: 20140707
