I'm very new to QGIS, and I have a sample GeoTIFF (and corresponding TFW) file(s) that I'm trying to determine what the longitude and latitude coordinates for each of the 4 corners of the image are – coordinates of 2 opposite corners of the image would also be okay.
I'm able to import the GeoTIFF as a raster layer in QGIS, but I noticed that all the coordinates that are displayed are in UTM format. In the metadata, I see the layer extent, which I was told are the UTM coordinates of the bottom-left and top-right of the corners of the image (square-shaped), which I can work with. However, I have to determine what the UTM zone is so I can use that along with the UTM coordinates in the metadata to convert the points to latitude and longitude.
This seems like a fairly simple task, but I'm unable to find out what the zone is of the image to move forward with the UTM to long/lat conversion.

If you enter the metadata proj string in Google search, you end up at http://spatialreference.org/ref/epsg/3477/proj4/ or
NAD83(NSRS2007) / Alaska zone 10. EPSG:26940 is basically the same.So it has nothing to do with UTM, rather state plane coordinate systems
