サマリー

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.

使用法

• [入力滑走路フィーチャ] パラメーターは、Z 対応である必要があります。

• The options you specify for the High Runway End Classification and Low Runway End Classification parameters will automatically populate most of the surface parameters.

• This tool creates the OIS in an existing polygon or multipatch feature class. The OIS can also be generated in an existing polygon shapefile. If a feature class is used as the Target OIS Features parameter value, it must include 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 the Custom JSON File parameter, use the CustomizeOIS.exe utility included in the Aviation Airports Product Data download 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 cut by the transitional and approach surface for output polygon features; however, the surface will be continuous for output multipatch features.

  レガシー:

  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.

• High Runway End refers to runway direction identifiers 19 through 36. Low Runway End refers to runway direction identifiers 01 through 18.

• If the runway classifications for the High Runway End Classification and the Low Runway End Classification differ, the primary, horizontal, conical, and transitional surfaces will be created to match the more restrictive classification. Surfaces will be created to cover a broader area.

• If processing multiple runway features, check the Include Merged Surfaces parameter to create an additional Merged Horizontal Surface and Merged Conical Surface.

  The additional merged surfaces will be continuous and will have an additional surface created to fill in the areas bounded by edges tangent to the outer edges of the individual surfaces.
