Importing Geo-Referenced iTIFF Files


Recommended Posts

This shouldn't be happening, it could be the result of rubbersheeting the tiff file to georeference it as that can create borders around the actual area at times. It looks like the projection is getting a bit wonky for some reason.
Do these black borders also show if you open the tiff file in an image editing program like photoshop or affinity photo or something similar?

You could remove the black background if it is also already in the tiff file by selecting the area with a selection tool and "delete" it to transparent or white, but it is really important to NOT change the file by actually deleting pixels as that will cause the tfw file and the tiff file to no longer match and will cause incorrect positioning and scaling.

Another option could be to crop the imported tiffs in VW to get rid of the black borders, make sure the borders of the cropping objects have no line width applied (i.e. line is set to none in the attributes palette)
