FEATURE ATTRIBUTE TABLES:

Datafile Name: ARTREF.DBF

FEATURE ATTRIBUTE TABLES CODES AND VALUES:

Item	Item Description
FID	Internal feature number.
SHAPE	Feature geometry.
COUNTY	The Florida county nearest to the artificial reef project
CONTRACT	The DEP:OFMAS contract number, if the reef is a grant funded deployment administered by OFMAS. If not, this field is blank
FEDGRANT	Federal Aid in Sportfish Restoration Program grant number, if the project was funded by that source. If not, this field is blank
GRANTEE	The recipient of the OFMAS or Federal grant. It may be other than the county, such as cities
AMOUNT	Amount (in dollars) of the grant if funded by OFMAS or Federal grants. No project amount data is available for non OFMAS grant projects
DEPLOYDATE	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)
REEFNAME	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
TYPE	This is a special type of reef that may be tracked. Currently there are three types WRECK = not intentionally placed BAY = inshore Bay waters MITIGATION = reefs placed for mitigation purposes
PERMIT_SIT	The common name for the permit site as it appears on the U.S. Army Corps of Engineers permits
COE_PERMIT	The Corps of Engineers (COE) active permit number for the site
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)). IS USED
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
TONS	Dry weight of the reef material deployed (in US tons) if known
VOLUMEFT3	volume of reef material in cubic feet, if known
VOLUMEYD3	volume of reef materials in cubic yards if known
FT_PRNT_FT	Footprint of the reef materials on the bottom in square feet
LORAN1	The first set of LORAN time delay coordinates for the reef
LORAN2	The second set of LORAN time delay coordinates for the reef
LATDD	Latitude in decimal degrees
LONGDD	Longitude in decimal degrees
DESCRIPTIO	This field contains the name of the ship if available
DEPTH	Depth (in feet) to the bottom at the time of deployment
RELIEF	The height (in feet) of the reef materials off the bottom, also known as profile
DIVE_DATE	The most recent date that OFMAS divers visited the site in month/day/year format
GPS	This field is a code to indicate which set of coordinates are presumed to be the most accurate, the lat/long or Loran. It represents how these more accurate coordinates were generated, if known. Values are; DGPS: these lat/long were taken by DGPS unit on the reef, GPS: these lat/long were taken by a non-differential GPS unit on the reef, LOR:these LORAN coordinates were taken by LORAN unit on the reef, PYB: these LORAN coordinates were taken directly from the 1997 edition of the "Atlas of Artificial Reefs in Florida: Fifth Edition," edited by Don Pybas, Florida Sea Grant. If blank, it is unknown how these coordinates were generated and which sets are most accurate
PREDIVE1	This stands for "previous dive 1" which would be the date of second most recent site visit by the OFMAS dive team. It is moved from the field "DIVEDATE" after a new site visit to the same reef was accomplished
PREDIVE2	This stands for "previous dive 2" which would be the date of third most recent site visit by the OFMAS dive team. It is moved from the field "PREDIVE1" after a new site visit to the same reef was accomplished
DEPLOYMUN	This is the code for deployments making up a separate "reef".A separate reef is defined by DEP as two deployments within 300 feet of each other (i.e. one 'reef' with two 'deployments'). If a reef is no closer than 300 feet to another reef, then it has a "1" in this field. If it is closer than 300 feet to its nearest neighbor it is given a 2,3, 4,...etc. for as many deployments that are within 300 feet of each other. Therefore, if a subset of "reefs" is needed, as opposed to "deployments", then a simple sort for all records with a "1" in this field will provide the number of separate reefs
DEPLOY	This is a 'yes' or 'no' field that indicates whether OFMAS staff were present for the deployment of the materials
PREDIVE3	This stands for "previous dive 3" which would be the date of fourth most recent site visit by the OFMAS dive team. It is moved from the field "PREDIVE2" after a new site visit to the same reef was accomplished
VOL_DIVE	Dates that any non-FWCC official dives were done on site
COAST	This field indicates whether the reef is in the Gulf of Mexico or the Atlantic Ocean G = Gulf of Mexico A = Atlantic Ocean
STATE	Whether the reef is in state or federal waters S = State F = Federal
SOURCE	Where the current sets of coordinates were originally obtained MPF = the FWC Materials Placement Forms, (Required by Chapter 370.25, Florida Statutes) Dive-Date = Dive date was an FWC field visit Pybase 97 = From 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) Field grant ID = Various monitoring grants to field truth locations or county staff
DESCRIPT	Based on MATERIAL1 field

USER NOTES:

Attribute accuracy is relied on the integrity of the attribute information within the originl data layer

A note concerning data scale: Scale is an important factor in data usage. Certain scale datasetsare not suitable for some project, analysis, or modelling 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. For more information regarding scale and accuracy, see our web pages at: http://www.geoplan.ufl.edu/education.html

DATA LINEAGE SUMMARY:

Data was created when an Excel file was converted to a dbase file with coordinates to 0.0001 decimal degrees. The dbase file was converted to a shapefile using the ArcMap "add X,Y data" tool. The shapefile was reprojected to Albers NAD 83 projection. Process Date: Unknown GeoPlan downloaded this dataset from the Florida Marine Research Institute website (http://www.floridamarine.org/). The was data downloaded as shapefile in projection: Albers, NAD 83, GRS 80. The dataset was projected from NAD 83 to FGDL Albers HPGN. -Reprojected data to FGDL Albers HPGN -Added a DESCRIPT field to attribute table based on REEFNAME -Deleted PREDIVE4 field which contained no data -Renamed shapefile from art_reef_new to ARTREEF Process Date: 2003
