please can you help me ? i have the same problem i want to remove project raster in arcgis 10.1
i send image which does not match with projection raster
I cannot see this option in 10.2 - is it possible to remove the spatial reference in 10.2?
Ben, my version is 10.3.1, but I am pretty sure it's the same in 10.2...
Right click on the dataset in Catalog. Scoot down to the Spatial Reference part, click edit to bring up the spatial reference properties page.
Click the little pull-down next to the world icon at the top. Click Clear.
Ah ha - it is the same, thank you.
And, in the case of external files like tiff or jpeg, you may have to use the normal win file explorer to delete any associated files like worldfiles - tfw, and any aux or xml.
