Several techniques are used in obtaining these data, including ground survey, remote sensing , manual entry or calculated values. The types of information typically collected consist of reference data including runway and navaid information, data relating to imaginary surfaces that define safe altitudes for approaches and landings (Obstruction Identification Surfaces or OIS as specified in the FAA’s Federal Aviation Regulations Part 77) including obstacle and obstructing areas, layout of an airport including aircraft movement areas, and features found at and near an airport of landmark value. Purpose: This information is used to develop instrument approach and departure procedures, to certify airports for certain types of operations, to determine maximum takeoff weights, to update aeronautical publications, to provide geodetic control for engineering projects, to assist in airport planning and land use studies, and for other miscellaneous activities.

Native_Data_Set_Environment: Microsoft Windows 2000 Version 5.0 (Build 2195) Service Pack 4; ESRI ArcCatalog 9.1.0.722 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The aeronautical data are a representation based on a combination of field survey and office interpretation of imagery. The attributes are verified by field and/or office review. Logical_Consistency_Report: All data are collected without dangles or gaps. Common sides may not be shared. Completeness_Report: The survey specified from the Federal Aviation Regulations Part 77 (FAR-77) Obstruction Identification Surfaces (OIS). Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Refer to FAA No. 405, Standards For Aeronautical Surveys and Related Products. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Refer to FAA No. 405, Standards For Aeronautical Surveys and Related Products for point data and FAA AC No: 150/5300-18, General Guidance and Specifications for Submission of Aeronautical Surveys to NGS: Field Data Collection and Geographic Information System (GIS) Standards, for linear vertical accuracies. Lineage: Process_Step: Process_Description: This product is a result of field and/or photogrammetric surveying. The surveys include runway and stopway data, navigational aid (NAVAID) data, obstacle data, and data on various airport features, including taxiways, aprons, and landmark features. The photogrammetric survey includes verifying and collecting survey data using stereoscopic (3-D)imagery. The data is exported from the digital photogrammetric software and imported into a Geographic Information System software for cartographic processes.
