TerrainAccessOperator.PositionInput Property
Gets or sets an operator that gives a start position as a point or line feature.
Syntax
public Operator PositionInput { get; set; }Property Value
Remarks
The operator calculates the travel times – the accessibility – from a given starting feature. This is usually a point feature, but it can also be a line feature, in which case all nodes are used collectively as starting points (the edges between the nodes are not used as starting points, so you may need to densify the line feature in some use cases).
The PositionInput can be null (no operator at all): this will activate a different mode of the TerrainAccessOperator where the accessibility is calculated from the road network. All the road features are used collectively as starting points, including both explicit road nodes and intermediate points on road edges. Note that the PositionInput will not be regarded as null if it is an operator that just happens to give no features, for example a ReadOperator connected to an empty dataset.
