GetSurfaceConstraints Method

In This Topic

Gets the list of SurfaceConstraint used in this LAS dataset. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

Visual Basic (Declaration)
C#

Public Function GetSurfaceConstraints() As IReadOnlyList(Of SurfaceConstraint)

public IReadOnlyList<SurfaceConstraint> GetSurfaceConstraints()

Return Value

An IReadOnlyList of SurfaceConstraint.

Exceptions

Exception	Description
ArcGIS.Core.Data.Exceptions.GeodatabaseException	A geodatabase-related exception has occurred.
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run

Remarks

Surface constraints are features whose geometry capture or define the characteristics of the surface. Breaklines, water polygons, or area clipping boundaries are all examples of surface constraints. Surface constraints can be feature classes or shapefiles.

Example

Get Surface Constraint information from a LAS Dataset

{
  var constraintCount = lasDataset.GetSurfaceConstraintCount();
  IReadOnlyList<ArcGIS.Core.Data.Analyst3D.SurfaceConstraint> constraints = lasDataset.GetSurfaceConstraints();
  foreach (var constraint in constraints)
  {
    var dsName = constraint.DataSourceName;
    var wksPath = constraint.WorkspacePath;
    var heightField = constraint.HeightField;
    var surfaceType = constraint.SurfaceType;
  }
}

Requirements

Target Platforms: Windows 11 Home, Pro, Enterprise (64 bit)

ArcGIS Pro version: 3.2 or higher.
