Member Function Documentation
| const SPATREF::COORDREFSYS& RASTERGEN_VIEWSHED::GetViewPointCRS | ( | ) | const [inline] |
Get viewpoint coordinate reference system.
| void RASTERGEN_VIEWSHED::SetHorizontalAngleRange | ( | const DOUBLE_RANGE & | HorizontalRange | ) | [inline] |
Set horizontal viewing angle range.
- Parameters:
-
HorizontalRange Viewing angle range (0-360 degrees)
| void RASTERGEN_VIEWSHED::SetMaximumDistance | ( | double | distance | ) | [inline] |
Set maximum view distance.
| void RASTERGEN_VIEWSHED::SetMinimumVisiblePoints | ( | int | MinVisiblePoints | ) | [inline] |
Set minimum number of visible viewpoints to be considered as in viewshed.
Default is 1 if not set.
- Parameters:
-
MinVisiblePoints Minimum number of points to be considered visible, 0 for all viewpoints
| void RASTERGEN_VIEWSHED::SetSourceRaster | ( | const RVC::OBJITEM & | ObjItemSourceRast | ) | [inline] |
Set source raster.
| void RASTERGEN_VIEWSHED::SetUseEllipsoidCurvature | ( | bool | UseCurvature | ) | [inline] |
Set whether to use ellipsoid curvature.
| void RASTERGEN_VIEWSHED::SetVerticalAngleRange | ( | const DOUBLE_RANGE & | VerticalRange | ) | [inline] |
Set vertical viewing angle range.
- Parameters:
-
VerticalRange Viewing angle range (-90-90 degrees)
| void RASTERGEN_VIEWSHED::SetVerticalScale | ( | double | scale | ) | [inline] |
Set vertical scale for elevation raster cell values.
| void RASTERGEN_VIEWSHED::SetViewPointCRS | ( | const SPATREF::COORDREFSYS & | ViewPointCRS | ) | [inline] |
Set viewpoint coordinate reference system.
If not set or undefined then viewpoints must be in source raster cell coordinates.
| void RASTERGEN_VIEWSHED::SetViewPointHeight | ( | double | height | ) | [inline] |
Set viewpoint height above terrain.
