TITLE: LARGE URBAN BOUNDARIES
Geodataset Name: FLURB Geodataset Type: SHAPE Geodataset Feature: POLYGON
GENERAL DESCRIPTION:
This dataset contains the Adjusted Urbanized Areas database that is a geographic database consisting of Adjusted Urbanized Areas in the State of Florida for 1993; wherein, the AUA contain the state-portion of adjusted CENSUS urban boundaries for urban areas with a 1990 CENSUS population greater than 50,000 people. DATA SOURCE(S): Federal Highway Administration SCALE OF ORIGINAL SOURCE MAPS: 1:100,000 DATE OF AUTOMATION OR SOURCE: NA GEODATASET EXTENT: State of Florida

FEATURE ATTRIBUTE TABLES CODES AND VALUES:
ITEM ITEM DESCRIPTION SHAPE Data attribute inherent to the ESRI shapefile format, which defines the data as a point, polyline, or polygon. AREA Area of polygon PERMIMETER Perimeter of polygons URBCODE The URBCODE provides the 3 digit HPMS Urbanized Area Code for the adjusted urbanized area. CENCODE The CENCODE provides the equivalent 4 digit CENSUS assigned Urbanized Area Code for the adjusted urbanized area. NAME The NAME field consists of a descriptive name for the polygon feature. DESCRIPT FGDL added item based on NAME
USER NOTES:
An urbanized area (UA) consists of densely settled territory that contains 50,000 or more people. A UA may contain both place and nonplace territory. The U.S. Census Bureau delineates UAs to provide a better separation of urban and rural territory, population, and housing in the vicinity of large places. At least 35,000 people in a UA must live in an area that is not part of a military reservation. For the 1990 census, the U.S. Census Bureau assigned a four-digit UA code based on the MA (Metropolitan Area) codes. Scale is an important factor in data usage. Certain scale datasets are 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 section and the Data Source Contact section of this documentation.

DATA LINEAGE SUMMARY:
This dataset was downloaded as a coverage by the GeoPlan Center from the FHWA Office of Intermodal and Statewide Programs webpage at http://www.fhwa.dot.gov/hep10/data/. Data was projected to FGDL Albers HPGN, descript item was added based on NAME, lowercase character items within attribute table were upcased, and old internal coverage items were dropped. When received, data was in UTM projection, Datum: NAD83, Spheroid: GRS1980, Units: Meters.MAP PROJECTION PARAMETERS
