KML Fails to Load v2

#1

Hi,

This is another issue very similar to this post for which I have no reply.

I am running the following code on the attached kml file.

KmlFeatureLayer kml = new KmlFeatureLayer(filename);
kml.RequireIndex = false;

            kml.Open();
            InMemoryFeatureLayer imfl = new InMemoryFeatureLayer();
            imfl.Name = name;
            foreach (Feature f in kml.FeatureSource.GetAllFeatures(ReturningColumnsType.AllColumns))
            {
                imfl.InternalFeatures.Add(new Feature(f.GetShape(), f.ColumnValues));
            }
            kml.Close();

I get the following error at the GetAllFeatures call

System.NullReferenceException: ‘Object reference not set to an instance of an object.’

I am using the kml library 10.6.1.

hi Damain,

Thanks for the code snippet and the kml file, I reproduced your issue.

I’ve fixed it in the develop branch, could you please upgrade your ThinkGeo.MapSuite.Layers.Kml to
11.0.0-beta021(which should be available in one or two days) and give it a try?

Thanks,
Leo

Thanks Leo.

I will be on the lookout for the update. Does it also fix the issue reported in the KML Fails to load post?

Hi Damian,

No, there’s something wrong with 21US_02170.kml, the line 61 shows as below, there’s no comma between the numbers, it’s not the standard format and we cannot parse it.

<coordinates>-90.4196 27.32</coordinates>

If you add a comma to make it right, everything works fine.

<coordinates>-90.4196,27.32</coordinates>

Thanks,
Leo

Thanks Leo.

New code is working. When will it be pushed to the stable release?

Hi Damian,

ThinkGeo.MapSuite.Layers.Kml 10.6.3 is available now. Feel free to upgrade ThinkGeo.MapSuite.Layers.Kml to 10.6.3 .
