VisibilityOperator.DesiredInputResolution Property
Gets or sets the desired resolution for the calculation nearest the observers, in meters.
Syntax
public AttributeVariable< System.Double > DesiredInputResolution { get; set; }Property Value
Default: 1.0
The desired resolution for the calculation nearest the observers, in meters.
Remarks
Raster datasets will often contain overviews in coarser resolutions, and an update of a View will normally request data in a resolution that is suitable for the current view resolution. However, the resolution of line-of-sight calculations should normally not depend on the current view resolution, so the value of the DesiredInputResolution will override the current view resolution when the operator requests elevation rasters and tree height rasters.
If the operator can be configured to calculate in multiple resolutions – see FirstResolutionChange – then the DesiredInputResolution refers to the high resolution that is used near the observer.
The raster data fetched for calculations near the observer will not be resampled to fit the DesiredInputResolution exactly. For example, if the property indicates a fine resolution of 1 meter while the finest available elevation data has 30 meter resolution, then the 30 meter elevations will just be used as they are.
The property should normally have a constant value, but since it is an attribute variable, its value can be made to depend on some of the View.UpdateAttributes. However, the value cannot be made to depend on attributes of any input features.
