Is it possible to add this geometry type?

Hi, @nielsbosma

We have reproduced this problem and created a ticket GISNET-1356. We will notify you here as we will have progress with it.

Thanks

Hi, @nielsbosma
We have explored your request.
We don’t support ‘Polygon’ type but we have field ‘WritePolygonsAsLines’ in our ‘ConversionOptions’.
Please, try to set ‘WritePolygonsAsLines = true’. In this case your example work fine.

code:
ConversionOptions options = new ConversionOptions();
options.DestinationDriverOptions = new Gis.Formats.Gpx.GpxOptions() { WritePolygonsAsLines = true };

Thanks, this worked for me as well!
