DATA VERSION: July 2004: This data set updates and replaces all previous versions of the Florida Master Site File historical structures data layer.  This version incorporates newly recorded structures and updates of previously recorded locations and attributes.

 

DATA CURRENCY: Data from the Florida Master Site File are continually updated.  On average, the Site File processes over 6,000 additional historic structure forms each year.  This data layer is only current as of the date of this document.  Contact the Florida Master Site File for updated data layers.

 

DATA SOURCE(S): Source data were created by the Division of Historical Resources. The original location information is based on field reports and address data which have been submitted to the Florida Master Site File 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 accuracy of submitted information cannot always be verified.

 

DERIVATION METHODS FOR DATA: Structure locations in this data layer were automated using one of three methods; address matching by DHR, on-screen digitizing by DHR, or automated by an external party.  The PLOT_MTHD field indicates whether a structure was address matched(M) by the FMSF, digitized(D) by the FMSF, or automated externally(X).  Roughly 60% of the structure locations (statewide) were generated by address matching.

 

The address matching was carried out using the geocoding function of ArcView 3.0a.  Addresses were matched against the ESRI U.S. Street Database(1997).  The line data for the ESRI database (based on Tiger line data) was digitized at a 1:100,000 scale.  Due to the small scale and numerous attribute errors in the reference street data, the geocoding process resulted in typical positional errors (as spot-checked against surveyor provided maps) of 20 to 100 meters with occasional larger errors possible.  In some cases this results in a structure location point appearing on the wrong side of the street or in the wrong block when displayed against a scanned 1:24,000 USGS quadrangle.  It is recommended that the data user compare the locations of the address matched structures to the ESRI U.S. Street Database and other background layers(such as scanned quads) to most accurately interpret locational information.

 

Not all structures and addresses adequately matched the ESRI U.S. Street Database.  Structures which did not address match were on-screen digitized in ArcView 3.0a, 3.1 and 3.2 using scanned, georeferenced (geographic coordinates, NAD27) USGS 1:24,000 quadrangles as a background.  Location information for these structures was culled from a variety of sources, including: surveyor-provided maps (the vast majority fall into this category), verbal location descriptions included on the site form, commercially available street atlases, county road maps, county property appraiser databases, city directories, and direct telephone contact with surveyors or property owners.  The accuracy of the digitized locations is, in general, somewhat better than that of the address matched structures.  However the overall coverage should be considered a 1:100,000 scale data layer.

 

A small number of structure locations in this data set were automated by an outside entity.  In general, these locations are deemed by the Site File to be of better quality/accuracy than those address matched by DHR.

 

After the data layers had been completed they were converted from ArcView shapefiles to ArcInfo coverages using the SHAPEARC command in ArcInfo 8.2.  In September 2003, the base coverages were converted to an ESRI GeoDatabase format and are currently maintained in GeoDatabase format.

-------------------------------

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 optional single letter character suffix (suffix letter is generally used to indicate sites that are functionally or spatially related).

SITENAME: The site name as recorded at the Florida Master Site File. Usually the principal or best known name for a cultural resource.  A site name of "NN" or a blank value indicates no name has been designated for the site.

ADDRESS: The street address of the site, including the number, prefix direction if relevant, and street name.

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 sites have an associated report or manuscript.

ARCHITECT: The name of the architect, designer, builder, landscape architect, or artist responsible for the actual DESIGN of the building, structure, or object being documented.  A blank value for this field indicates that this information is not known or is not recorded in the Florida Master Site File database.

YEARBUILT: The year of actual construction, as documented or estimated.  A "C" (circa) indicates the year given is only roughly known or estimated.  A "+" indicates the year given is the earliest possible year of construction.  A "-" indicates that the year given is the latest possible year of construction.  A blank value for this field indicates that this information is not known or is not recorded in the Florida Master Site File database.

STYLE: The architectural style or period which best describes the site.

EXTPLAN: General exterior plan of the structure.

STRUCSYS1: Major structural system(s) employed in the structure.  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.  A blank value for this field indicates that this information is not known or is not recorded in the Florida Master Site File database.

STRUCSYS2: Major structural system(s) employed in the structure.

STRUCSYS3: Major structural system(s) employed in the structure.

EXTFABRIC1: Major exterior fabric(s) used on the structure.  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.  A blank value for this field indicates that this information is not known or is not recorded in the Florida Master Site File database.

EXTFABRIC2: Major exterior fabric(s) used on the structure.

EXTFABRIC3: Major exterior fabric(s) used on the structure.

EXTFABRIC4: Major exterior fabric(s) used on the structure.

STRUCUSE1: Use or function of the structure.  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.  A blank value for this field indicates that this information is not known or is not recorded in the Florida Master Site File database.

STRUCUSE2: Additional use or function of the structure.

STRUCUSE3: Additional use or function of the structure.

SURVEVAL: Surveyor's evaluation of the cultural resource's eligibility for the National Register when the resource is considered as an independent entity - not as a component or "contributing property" to a potential district.

SURVDIST: Surveyor's evaluation of cultural resource's eligibility for the National Register as part of a district or thematic group.

SURVLOCAL: Surveyor's evaluation of a cultural resource's eligibility for listing on a local government's register of important sites

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.

D_NRLISTED: Date that the property was officially listed on the National Register of Historic Places (NRHP).  The field is blank if the FMSF database does not indicate the property is National Register listed.

PLOTMTHD: Indicates whether the structure was address Matched(M) by DHR, on-screen Digitized(D) by DHR, or automated by an external individual or organization(X).  Refer to the discussion of data derivation methods for more details.

 

WARNINGS TO THE USER: The locations of archaeological sites, historic structures, unmarked human burials, cemeteries, and other cultural features contained in this (and other) Florida Master Site File data layers are for resource management, law enforcement, and research purposes only.
