GeometryConversionOperator Class
Converts feature geometries between different geometry types.
NuGet/Assembly: Carmenta.Engine.5.17.0.nupkg (in the CEOperators assembly)
Syntax
public class GeometryConversionOperator : UnaryOperatorRemarks
This operator converts between different feature geometry types, including triangulation of polygons and rasters to meshes. The conversions that can be performed are:
From | To | Comment |
|---|---|---|
Line | Polygon | |
Line | Point | Each node of the line will produce a point feature with two new attributes, gcopNodeIndex and gcopReverseNodeIndex. The value of gcopNodeIndex gives the zero-based index of the point in the line geometry, so the first point gets 0, the second point gets 1, etc. The value of gcopReverseNodeIndex is similar but in the reverse order, so the last point gets 0, the next to last point gets 1, etc. |
Polygon | Line | |
Polygon | Point | One point for each node in the polygon rings |
Polygon | Mesh | A mesh that represents the surface of the polygon |
Raster | Polygon | A polygon that covers the raster |
Raster | Line | A line that outlines the edge of the raster |
Raster | Point | One point for each corner of the raster |
Raster | Mesh | A mesh that represents the surface of the raster if the cell values are interpreted as height values. This conversion uses MaxError and EdgeCurtains. |
Mesh | Point | One point for each mesh node |
Mesh | Raster | A raster covering the extent of the mesh with resolution defined by pixel size. |
