Creates obstruction identification surfaces (OIS) based on the FAA Advisory Circular 150/5300-18B specification. These OIS assist in the identification of possible hazards to air navigation and critical approach/departure obstructions within the vicinity of the airport and are used to support planning and design activities. The type, function, and dimension of a surface differ by its runway classification. This tool creates surfaces such as a polygon or multipatch features
Использование
Параметр Входные объекты взлетно-посадочной полосы должен поддерживать z-значения.
When Runway Classification is set to Vertical Guidance, the output transitional surface will be split into four sections by a line perpendicular to the runway centerline.
When Runway Classification is set to Vertical Guidance, the output conical and horizontal surfaces will be split into sections by a meridian and a parallel. The meridian intersects the Airport Elevation Point and the centerpoint of the runway centerline. The parallel runs perpendicular to the meridian through the centerpoint of the runway centerline.
Примечание:
In the absence of Airport Control Point Feature Class parameter values, the split will be based on the runway endpoint and runway centerpoint. The split will then draw a line from the runway endpoint and runway centerpoint and form a line parallel and perpendicular to the runway centerline.
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.
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 XYZ geometry for an Airport Elevation feature, Displaced Threshold features, or both. If displaced thresholds are included, surfaces will be constructed based on their XYZ geometry instead of their corresponding Input Runway Feature 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.

in_features | The input runway dataset. The feature class must be z-enabled and contain polylines. | Feature Layer |
target | The target feature class that will contain the generated obstruction identification surfaces. | Feature Layer |
runway_type | Specifies the runway classification of in_features.
| String |
highend_clear_way_length (Дополнительный) | The length of the area at the high end of the runway. The unit of measurement is based on the input runway features. | Double |
lowend_clear_way_length (Дополнительный) | The length of the area at the low end of the runway. The unit of measurement is based on the input runway features. | Double |
airport_elevation (Дополнительный) | The highest elevation on any of the runways of the airport. The value should be given in the vertical coordinate system linear units of the target feature class. If no value is given, the highest point on the Input Runway Features will be used. | Double |
include_merged_surface (Дополнительный) | Indicates whether merged horizontal and conical surfaces are included in the OIS in addition to the regular surfaces.
| Boolean |
custom_json_file (Дополнительный) | The import configuration, in JSON format, that creates the custom OIS. | File |
airport_control_point_feature_class (Дополнительный) | The point features containing an Airport Elevation feature, Displaced Threshold features, or both. Values entered into the Airport Elevation parameter will take precedence over these point features. | Feature Layer |
