Hello, I'm working in C# using the gdal c# wrappers and am trying to write multiple gps shape types (waypoints AND tracks AND routes) to a single GPX file. When creating a GPX layer I am required to define an shape type:
layer = ds.CreateLayer(outputLayerName, sr,wkbGeometryType.wkbMultiLineString25D, new string[] { }); But if I do that then I can only write a single gps shape type to that file, otherwise I get an error: "ogr_csharp - Features without geometry or with non-ponctual geomemetries not supported by GPX writer in waypoints layer." [cid:image001.png@01CCDA7D.45A462B0] Does anyone know what I may be doing wrong?
