The Public-Use Airports database is a geographic point database of aircraft landing facilities in the United States and U.S. Territories. Attribute data is provided on the physical and operational characteristics of the landing facility, current usage including enplanements and aircraft operations, congestion levels and usage categories. This metadata record was copied from the Bureau of Transportation Statistics and modified slightly for use with the WV dataset. Purpose: The database provides locational and attribute information for use in national and regional cartographic and spatial analysis applications.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Airport attributes were obtained from four different Federal Aviation Administration (FAA) sources: the National Flight Data Center Airport Master Record (NFDC 5010) database; the National Plan of Integrated Airport Systems (NPIAS) database; the Air Carrier Activity Information System (ACAIS) database, and the Terminal Area Forecast (TAF) file. Each database has its own collection and quality control procedures, and all are maintained by separate offices in FAA. Where two or more of the databases included a similar attribute field, an assessment was made as to which value was more current and/or more accurate based on its data collection procedures. Attributes derived from the same source are grouped together. For each ASCII attribute file a corresponding dBase format attribute file is supplied. Due to the requirement for the file name extension 'dbf', the Attribute file number is included in the file name prefix (AIRPORT.T02 contains the same attributes as AIRPORT2.DBF). In all attribute files, a number of the attributes contain 'blank' in addition to the values enumerated in the domain. In attribute file two (AIRPORT.T02), the National Emergency Status field (NAT_EMER_STAT) contains values not enumerated in the domain. It is a composite field that may contain multiple values separated by '/'. The non-enumerated values include: 3, X, N, 8/N, and 'blank'. Although some records were modified, the data provider supplied no modification date(s), nor any change code in the REVISION field. Logical_Consistency_Report: All point records are represented by a single coordinate pair and a unique feature identifier -- the landing facility's location identifier (LOCID) assigned by the FAA. Attribute data is matched to specific point records using this LOCID. Completeness_Report: Landing facilities in this database consist of those identified in the NFDC 5010 database to be either publicly owned, or privately owned but open to the public, or owned by the U.S. military. The following landing facilities have been excluded: private landing facilities not open to the public, glider ports and ultra light landing facilities, as well as landing facilities that do not have a current LOCID assigned to them. Because the NFDC 5010 database is the most comprehensive of the four FAA databases with respect to number of landing facilities, i.e., it contains data on all of the landing facilities in the airports database, attribute data associated with the other FAA databases may be missing from certain records, particularly those of smaller general aviation or military landing facilities. In particular, in attribute file AIRPORT.T02 (NFDC), a blank in an attribute field for a particular landing facility could signify either that an entry is not applicable or that the data is missing. Only in some cases will the user of the data be able to determine which case applies. In attribute files AIRPORT.T01 (ACAIS), AIRPORT.T03 (NPIAS), and AIRPORT.T04 (TAF), a blank in an attribute field for a particular landing facility always indicates, unless otherwise noted, that the landing facility is not included in the particular database and that, therefore, there should not be any data on that attribute for that particular landing facility. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: This is based on coordinate data provided in the NFDC 5010 database. These coordinate data identify the approximate location of the Airport Reference Point (ARP) as reported by the landing facility on the NFDC 5010 form. According to NFDC guidelines, the location of the ARP should be reported to a horizontal accuracy of one arc second of latitude and longitude. However, the accuracy of these reported coordinates are not verified by FAA. The records were loaded into a GIS and checked visually for any unusual or obviously erroneous locations. Grossly incorrect locations were repositioned using Census TIGER/Line files or USGS digital line graphs (DLG) as reference layers. No more than five records required repositioning in this manner. Further accuracy checks using the NTAD states database and the Digital Chart of the World as reference layers revealed no further positioning errors with the 1:100,000 NTAD database, but about five airports on islands appeared to be slightly in the ocean according to the 1:1,000,000 scale Digital Chart of the World. Comparison of the NTAD layout of Puerto Rico with that of the Digital Chart of the World revealed enough of an error in the Digital Chart of the World's location of Puerto Rico to think that Saint Thomas' airport, which appeared to be in the ocean according to the Digital Chart of the World, might really be on land, given the known high accuracy of most of the airport coordinates obtained from the NFDC 5010 database. Therefore, the few airports that appeared to be slightly off of their islands according to the Digital Chart of the World were left at their original coordinates. When compared with the NTAD STATES database, approximately 120 airports appear to lie off-shore or not within the state boundary based upon the STFIPS Code attribute Five facilities are identified as requiring additional review to properly locate the facilities. The facilities in question are: POINTID FEATURID STFIPS DESCRIPT 2498 ADW 24 Andrews AFB 3253 DC13 11 Walter Reed Forest Glen 5077 NK29 36 Southampton Village 5170 NY93 36 Charles Poletti 6492 WA65 53 Washington National Guard - Sinclai For example, the Charles Poletti facility is coded as existing in New York state. The coordinates place it in Pennsylvania. The airport points should carry the same longitude and latitude values as the airway segment endpoints (carrying the LOCID as FEATURID to match the points and nodes). In most cases they do. The longitude and latitude value for Denver International Airport (DEN) does not match the value for the associated node. Airport longitude, latitude point = -104.667002, 39.858408 Airway node longitude, latitude = -104.879755, 39.774292 Lineage: Source_Information: Source_Citation: Citation_Information: Originator: Federal Aviation Administration Publication_Date: 199509 Title: National Flight Data Center Airport Master Record Database Publication_Information: Publication_Place: Washington, DC Publisher: Federal Aviation Administration Type_of_Source_Media: magnetic tape Source_Time_Period_of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: 199509 Source_Currentness_Reference: publication date Source_Citation_Abbreviation: NFDC 5010 Source_Contribution: Facility location, name and other identification, physical description, ownership, FAA certification, military and customs landing rights, number of runways and helipads.
