Geo Tiff Layer will not draw

[Steven1]

Hi,

We have a number of Geo Tiff files that we cannot view in our WinFormsMap. We receive the following error when the layer draws:

System.NullReferenceException
HResult=0x80004003
Message=Object reference not set to an instance of an object.
Source=ThinkGeo.MapSuite.Layers.GeoTiff
StackTrace:

Here is a link to one of the Tiffs, can you please take a look and see what the problem is?

Thanks!

Hey @Steven1,

Looking at your GeoTIFF, it looks like it’s a tiled tiff and we didn’t support those in MapSuite 10 (we do in the latest version). However, to workaround this, you can open these GeoTIFFs in QGIS and use their export with “Rendered Image” as the output method:

Then you can load up those exported images in MapSuite:

Thanks,
Kyle
