ReplaceNaNZs Method (IGeometryEngine)
Replaces each non-simple (NaN) Z-value on the geometry with the specified z-value. All other simple (non-NaN) z-values are unchanged.
Parameters
- geometry
- The geometry to replace non simple Zs.
- zValue
- The Z-value to assign.
Return Value
A geometry in which each coordinate has a simple (non-NaN) Z-value.
Replace NaN Zs in a polygon
List<Coordinate3D> coordsZ = new List<Coordinate3D>()
{
new Coordinate3D(1, 2, double.NaN),
new Coordinate3D(4, 5, 3),
new Coordinate3D(7, 8, double.NaN)
};
Polygon polygon = PolygonBuilderEx.CreatePolygon(coordsZ);
// polygon.HasZ = true
Polygon polygonZReplaced = GeometryEngine.Instance.ReplaceNaNZs(polygon, -1) as Polygon;
// polygonZReplaced.Points[0].Z = -1
// polygonZReplaced.Points[1].Z = 3
// polygonZReplaced.Points[2].Z = -1
