GenerateOISProfileJSON

概要

Generates a JSON string that represents the RunwayCenterline, OIS, obstacles, and elevation along the profile of the approach surface, storing the result in an existing OIS Multipatch layer.

ライセンス:

This function requires anArcGIS Aviation Airports license.

ディスカッション

The GenerateOISProfileJSON function is used to create a standard format that provides a view of runway and approach surfaces as well as any obstructions and terrain (maximum and minimum) that can be used in web-based applications. The information contained in the JSON allows you to create a representation of the runway and approach profile similar to the Terrain and Obstacle Profile tool. This information will be stored in a text field on the OIS Multipatch called profileJSON. If you specify an obstacle feature class to be included, that information will be stored in the obstacleJSON field.

メモ:

The profileJSON and obstacleJSON text fields must already exist in the OIS Multipatch feature class to be populated. Since these fields need to contain a long JSON string, the field length should be a minimum of 50,000 characters. A larger field size may be required depending on the source data and sampling distance used. The function will report an error to increase the field length if necessary.

構文

GenerateOISProfileJSON (runway_centerline, ois, demRaster, {sampling_distance}, {obstacle}, {profile_OIS}, {profile_Runway}, {curved_path})

パラメーター	説明	データ タイプ
runway_centerline	A z-aware polyline layer that contains the centerline of the runway. The recommended input is RunwayCenterline from the Airports 18B data model or ADHPSurfaceLine from the AIS data model. At least one of the following fields is required: DESIGNATOR_TXT or RWYDESG.	Layer
ois	A multipatch layer that represents the approach surface. メモ: The recommended input is ObstructionIdSurface_MP from the Airports 18B data model. The following fields are required: DESCRIP OBSTACLEJSON PROFILEJSON RWYDESG	Layer
demRaster	A layer of a raster dataset.	Layer
sampling_distance	The size of the sampling distance in meters.	Double
obstacle	A z-aware point layer that contains the obstacles. メモ: The recommended input is ObstructionIdSurface_MP from the Airports 18B data model. The following fields are required: DISTVERT_UOM ELEV_VAL HEIGHT_VAL HORIZACC_UOM HORIZACC_VAL OBSTACLETYPE_CODE or TYPE_CODE VERTACC_UOM VERTACC_VAL	Layer
profile_OIS	Specifies whether points other than the end points are added for the OIS. False —Only end points are in the JSON. This is the default. True —Multiple points are added in the JSON based on the sampling distance.	Boolean
profile_Runway	Specifies whether points other than the end points are added for the runway. False —Only end points are in the JSON. This is the default. True —Multiple points are added in the JSON based on the sampling distance.	Boolean
curved_path	The curved_path layer that contains the path used to create curved approach.	Layer
