Resumen
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.
Uso
El parámetro Entidades de pista de entrada debe estar habilitado para z.
The selections you make in High Runway Designator Classification and Low Runway Designator Classification 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 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.
Sintaxis
FAAFAR77(in_features, target, high_runway_end_type, low_runway_end_type, {specially_prepared_hard_surface_runway}, {highend_clear_way_length}, {lowend_clear_way_length}, {airport_elevation}, {include_merged_surface}, {custom_json_file}, {airport_control_point_feature_class})| Parámetro | Explicación | Tipo de datos |
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 |
high_runway_end_type | Specifies the classification of the high end of the runway.
| String |
low_runway_end_type | Specifies the classification of the low end of the runway.
| String |
specially_prepared_hard_surface_runway (Opcional) | Specifies whether the runway has a specially prepared hard surface. A specially prepared hard surface indicates that the primary surface extends 200 feet beyond each end of the runway.
| Boolean |
highend_clear_way_length (Opcional) | 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 (Opcional) |
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 (Opcional) |
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 (Opcional) | Indicates whether merged horizontal and conical surfaces are included in the OIS in addition to the regular surfaces.
| Boolean |
custom_json_file (Opcional) | The import configuration, in JSON format, that creates the custom OIS. | File |
airport_control_point_feature_class (Opcional) | 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 |
Salida derivada
| Nombre | Explicación | Tipo de datos |
| derived_outfeatureclass | The updated feature class containing the generated obstruction identification surfaces. | Feature Layer |
