Analyze Runway Obstacles (Aviation)

Доступно с лицензией Aviation Airports.

Краткая информация

Analyzes obstacle data and obstruction identification surfaces (OIS) to determine if obstacles are penetrating.

Использование

• The Input OIS Features parameter must be a multipatch feature class that contains the OIS.

• The Input Obstacle Features parameter must be a point, line, or polygon feature class and must be z-aware.

• The Obstacle Height parameter will default to Feature Geometry, meaning it assumes that the height of the obstacle is captured as the z-value. Otherwise, you can specify a field in the feature class that contains the height values.

• For Obstacle Features, if Absolute height is chosen, the z-value is calculated from the mean sea level. If Relative height is chosen, the z-value is calculated from the ground level.

• A point feature is generated for each obstacle feature that falls within the area covered by the OIS. The x- and y-point coordinates are the same as the obstacle point feature with which the output point is associated. The z-value of the geometry is the altitude of the OIS at the obstacle location.

• Multipoint features will be generated when the input obstacle data is a polyline or a polygon.

• The output point features will contain the following fields:

  • Obs_OID—The Object ID of the input obstacle.
  • Z—The Absolute height or the Relative height value of the input obstacle.
  • GROUND_ELEV—If Relative height is chosen, the value of the elevation source of the obstacle. This will be zero if Absolute height is chosen.
  • OIS_Z—The altitude of the OIS at the obstacle location.
  • Delta_Z—The difference in elevation between the top of the obstacle and the OIS.

    Примечание:

    Positive values indicate obstacle penetration of the OIS.

  • OBSTACLETY—The field value from the input obstacle.

  

• All calculations and analysis are performed using values in the horizontal and vertical coordinate systems of the input OIS feature class. The output feature class is created with those same input OIS feature class coordinate systems.
