[gdal-dev] Using GDAL (MaxRev.GDAL) to write TAB files with mixed geometry

[Michael Tjener Pallesen (MTP)]

Hi

I'm migrating from calling native MiTAB operations for exporting features to a MapInfo TAB file to using GDAL and the MapInfo driver. I'm using C# and MaxRev.Gdal.Core package (and MaxRev.Gdal.WindowsRuntime.Minimal)
https://github.com/MaxRev-Dev/gdal.netcore

But when I try to export features that has geometry collections with mixed geometry types, GDAL creates multiple features in the TAB file.

If I try a feature with a collection of polygons, all is good too.. 1 feature with 2 polygons.

My old code calling MiTAB directly works fine.

Simple code showing the issue

{
        // Register the OGR library
        Ogr.RegisterAll();

        // Create a new MapInfo Tab file
        DataSource ds = Ogr.GetDriverByName("MapInfo File").CreateDataSource(@"c:\temp\playground.tab", null);

        // Create a layer
        Layer layer = ds.CreateLayer("layer", null, wkbGeometryType.wkbUnknown, null);

        // Create a feature
        Feature feature = new Feature(layer.GetLayerDefn());

        // Create a MultiGeometry
        Geometry multiGeometry = new Geometry(wkbGeometryType.wkbGeometryCollection);


        // Add polygons and polylines to the MultiGeometry
        Geometry polygonGeometry = Geometry.CreateFromWkt("POLYGON ((0 0, 0 1, 1 1, 1 0, 0 0))");
        Geometry polylineGeometry = Geometry.CreateFromWkt("LINESTRING (2 0, 3 0, 3 1, 2 1)");

        multiGeometry.AddGeometry(polygonGeometry);
        multiGeometry.AddGeometry(polylineGeometry);

        // Set the MultiGeometry as the feature's geometry
        feature.SetGeometryDirectly(multiGeometry);

        // Create the feature in the layer
        layer.CreateFeature(feature);

        // Cleanup
        feature.Dispose();
        ds.Dispose();
}

I have asked this question on gis.stackexchange too which lead to this mail. Here a user tried the same simple test without using MaxRev's version and came to the same result.
