FEATURE ATTRIBUTE TABLES:

Datafile Name: SHPO_BRIDGES_JUL06.DBF

FEATURE ATTRIBUTE TABLES CODES AND VALUES:

Item	Item Description
SITEID	This is the official state site number assigned by the Florida Master Site File. The state site number is an eight character string containing a two character county code, a five character numeric code, and an optionalsingle letter character suffix (suffix letter is generally used to indicate sites that are functionally or spatially related).
SITENAME	The bridge name as recorded at the Florida Master Site File. This is usually the principal or best known name for a cultural resource.
SURVEYNUM	The serial number assigned by the Site File to the manuscript produced by the project which identified or reexamined the cultural resource. Not all bridges have an associated report or manuscript.
FDOTNUM	The FDOT number is six positions in length, with the first two numbers as the defining code for the county. The remaining four positions are used as a unique number for the bridge within the county. A zero value for this field indicates there is no FDOT number for the bridge.
YEARBUILT	The initial date of the bridge's physical construction. A value of 'UNKN'for this field indicates the year of construction is unknown.
CONDITION	The overall condition of the bridge.
LENGTH	Overall length of the bridge in feet.
ENGINEERS	The primary designers/engineers of the bridge if known.
OWNERSHIP	Ownership type.
DESIGN1	Bridge design.
DESIGN2	Additional bridge design.
MATERIAL1	Construction material.
MATERIAL2	Construction material.
INUSE	Indicates whether or not the bridge is currently in service. YES = for in service. NO = for not in service. Blank = if not recorded.
D_NRLISTED	Date that the site was officially listed on the National Register of HistoricPlaces (NRHP). The field is blank if the FMSF database does not indicate the property is National Register listed.
SHPOEVAL	Evaluation of Florida's State Historic Preservation Officer (SHPO) concerning the eligibility of the resource for listing on the National Register of Historic Places. In Florida, the SHPO is the Director of the Division of Historical Resources, acting through staff in the Bureau of Historic Preservation (BHP). Generally the Site File database only contains evaluations made by the Compliance Review staff of BHP. Some properties may be listed on the NRHP without having been reviewed by Compliance Review staff. Therefore, an NR list date (indicating a property is NR listed) takes priority over a 'Not Evaluated by SHPO' value in this field. Values in this field are limited to a discrete list of possibilities used in the Site File database lookup table. Contact the Site File for more information.
DESCRIPT	Based on SITENAME
FGDLAQDATE	Date FGDL obtained data from source.

USER NOTES:

This data is provided 'as is'. GeoPlan relied on the integrity of the original data layer's topology

This data is provided 'as is' by GeoPlan and is complete to our knowledge.

GeoPlan relied on the integrity of the attribute information within the original data. The historical bridge data are based on field reports which have been submitted by many and varied individuals, groups, institutions, and cultural resource firms. Submissions to the Site File are sometimes accepted from amateurs as well as professionals. The locations are only as accurate as the locational information submitted to the Site File by the site recorder. The accuracy of submitted information cannot always be verified. The absence of a cultural resource in this data layer does not preclude the existence of an unrecorded resource in the field. The bridges recorded at the Site File represent only a fraction of the historic bridges present statewide. The locations of archaeological sites, historic structures, unmarked human burials, bridges, and other cultural features contained in this (and other) Site File data layersare for resource management, law enforcement, and research purposes only. State law protects archaeological remains on state owned and controlled lands (section 267.13, Florida Statutes). State law protects human burial sites on all lands (sections 872.02 and 872.05, Florida Statutes).

A note concerning data scale: Scale is an important factor in data usage. Certain scale datasetsare 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. 1:250000 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:

This data was originally created by the Division of Historical Resources. This data layer is maintained by on-screen (heads-up) digitizing bridge locations in ESRI ArcMAP. Scanned, georeferenced, 1:24,000 scale USGS quadrangles in geographic coordinates (lat./long., NAD27) are used as the background reference images. Process Date: Unknown When received, the data was in the following projection: Geographic, Datum: NAD27, Spheroid: Clarke 1866, Units: Decimal Degrees. The shapefile was projected to FGDL Albers HPGN (See "Map Projection Parameters" below) in ArcToolBox using the Florida Harn Transformation. -Reprojected to FGDL Albers HPGN -Added DESCRIPT field based on SITENAME to attribute table -Added fields FGDLAQDATE -Upcased all items in the attribute table -Changed file name to shpo_bridges from HistoricalBridges Process Date: 20060817
