This question already has an answer here:
I have a single band, 8-bit, unsigned integer tif (National Land Cover Data). When I view it in Arcmap 10.4.1, I am given the opportunity to also view it's attribute table:
However, when I view this same tif in QGIS 2.16.3, there is no option to open the attribute table:
With QGIS I can also load the tif's .dbf file, which contains the attribute data, but I don't see how to join that to the tif.
In summary, how do I view a tif's associated attribute data?
