CCITT3 (), PackBits. Supported TIFF tag compressions: 1, 3, 32773

The good news is that I can recommend you a workaround to use the contents of the TIFF file with the unsupported compression method. Let's move on...

You can quickly check the compression method with http://portableapps.com/apps/graphics_p ... w_portable and you are also able to convert the file to a supported TIFF or JPEG. Please follow this tutorial below:
Checking the compression in TIFF with IrfanView:

(just to be sure...)

Recommended file conversion workflow:
Open this TIFF file in IrfranView, then save as JPEG:


Copy the .TFW WORLD file to clipboard:

Then Paste it as a .JGW file (this file holds the data for georeferencing)



Finally this JPEG file can be added to DigiTerra Explorer.


If there is any question please let me know
