Résumé
Generates a JSON string that represents the RunwayCenterline, OIS, obstacles, and elevation along the profile of the approach surface.
Discussion
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 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.
Syntaxe
GenerateOISProfileJSON (runway_centerline, ois, demRaster, {sampling_distance}, {obstacle}, {profile_OIS}, {profile_Runway}, {curved_path})
Paramètre | Explication | Type de données |
runway_centerline | A z-aware polyline layer that contains the centerline of the runway. At least one of the following fields is required: DESIGNATOR_TXT or RWYDESG. | Layer |
ois | A multipatch layer that represents the approach surface. The following fields are required:
| 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. The following fields are required:
| Layer |
profile_OIS | Determines if points other than the end points are added for the OIS.
| Boolean |
profile_Runway | Determines if points other than the end points are added for the runway.
| Boolean |
curved_path | The curved_path layer that contains path used to create curved approach. | Layer |

GenerateOISProfileJSON example - Straight Approach
This script updates the profileJSON field with the information about the runway and approach profile as well as the obstacleJSON field with the obstacle information.
