FEATURE ATTRIBUTE TABLES:

Datafile Name: GDT_AIRPORTS_JAN09.DBF

FEATURE ATTRIBUTE TABLES CODES AND VALUES:

Item	Item Description
OBJECTID	Internal feature number.
NAME	Facility Name
FCC	Feature class code
LOC_ID	3 or 4 digit FAA official locator ID. Unique for each airport in the U.S.
USE	The two-character code in this field identifies the airport as either: 'PU' = public; 'PR' = private
DESCRIPT	Description field based on NAME
FGDLAQDATE	FGDL added field based on date downloaded from source
SHAPE	Feature geometry.
AUTOID	Unique ID added by GeoPlan
SHAPE.AREA	Area in meters
SHAPE.LEN	Perimeter in meters

USER NOTES:

All segment strings that form the airport boundaries must have closure to form polygons. Airport boundaries are not generalized.

The Airport layer represents all D58 and D59 polygon feature classes. After processing, the dataset is checked for drawing display, number of records, file sizes and then compared with the contents of the Tele Atlas(R) database at the time of creation.

GeoPlan relied on the integrity of the attribute information within the original data.

Airport polygon landmarks in this product are intended to be useful for cartographic purposes. The Airport layer was designed to be used in conjunction with other Landmarks and Street layers to create visually appealing maps and to be displayed with maximum drawing speed for Internet applications. The Airport layer was not intended to represent a current and complete list of all airports public, private or military in all states.

Airport boundaries allow for six implied decimal places of precision. Minimum baseline horizontal accuracy is consistent with 2000 TIGER/Line(R) files where airport polygons border streets. On-going realignment work on the Tele Atlas(R) database may result in horizontal accuracy of 12 meters or better for airport boundaries in some areas.

The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist. Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. The University of Florida GeoPlan Center shall not be liable for any damages suffered as a result of using, modifying, contributing or distributing the materials. 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.

REFERENCES: DATA LINEAGE SUMMARY:

Tele Atlas(R) extracts the dataset quarterly from the Tele Atlas(R) database using proprietary software. Data then is converted into multiple GIS formats. ISO quality standards are enforced throughout the production process. Data originally released by Tele Atlas in January 2009 on DVD. When received, data was in the following projection: Geographic Lat Long Datum D_WGS_1984, Units: Decimal Degrees. The GeoPlan QA/QC and standardization process included the following steps: 1. The data was renamed from flxxxap to gdt_airports_jan09.shp 2. The data was reprojected to FGDL Albers HPGN map projection. 3. Added DESCRIPT field based on NAME 4. Added field FGDLAQDATE 5. Standardized Metadata Process Date: 20090216 Data imported to ArcSDE and exported as a shapefile. Process Date: 20090305
