摘要

Creates obstruction identification surfaces (OIS) based on the FAA Part 77 specification. This regulation establishes standards and notification requirements for objects affecting navigable airspace. The type, function, and dimension of a surface differ by its runway classification. This tool creates surfaces as a polygon or multipatch features.

使用情况

  • 输入跑道要素参数必须启用 Z 值。

  • The selections you make in High Runway Designator Classification and Low Runway Designator Classification parameters will automatically populate most of the surface parameters.

  • This tool creates the OIS in an existing polygon or multipatch feature class. It can also be generated in an existing polygon shapefile. If a feature class is selected for Target OIS Features, it must have a vertical spatial reference.

  • For military airports, the outer horizontal surface is merged as well as the horizontal and conical surfaces.

  • To create a JSON file for Custom JSON File, use the CustomizeOIS.exe file that is part of the ArcGIS Aviation data package available from My Esri.

  • The Airport Elevation parameter has a default value of 0. If you use an elevation value greater than 0, it takes precedence and overrides any existing airport elevation value read from the Input Airport Control Point Feature parameter.

  • The Input Airport Control Point Feature parameter can be used to supply x-, y-, and z-geometry for the Airport Elevation parameter, displaced threshold point features, or both. If displaced threshold points are included, surfaces will be constructed based on their x-, y-, and z-geometry instead of their corresponding Input Runway Feature parameter endpoint.

  • OIS tools are flexible and accept a variety of input and output feature class types. For more information, see the OIS Input and Output schemas.

  • The horizontal surface generated by this tool will be continuous across the multipatch feature.

    旧版本:

    In ArcGIS Pro 2.6.x and earlier versions, the horizontal surface generated by this tool will be cut by the transitional or approach surfaces.

Approach clearance surface slope is 50 to 1 to an elevation of 500 feet above airport elevation. It then rises horizontally to 50,000 feet. Transitional surface slope is 7 to 1 outward and upward at right angles to the runway centerline. See section 77.28 in the FAR Part 77 specification for more information.
