Description:
  Abstract:
  The eAOC is a collection of geospatial data that has been determined to be relevant to air transportation on and near airports. 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.

      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.
