I have close to zero GIS background.
My goal is to extract only a certain UTM zone of this land use tiff file. I only know how to do that via specifying lat lon clipper box, however right now Qgis only shows things in pixel coordinate. Is there any way I can:
i. change project coordinates to lat/lon, or ii. extract UTM zone straight from the current one (meters from origin @ 45N100W)?
The docs show the projection as Lambert Azimuthal Equal Area Central Meridian -100.0, Lat of Origin 45.0 which to my knowledge corresponds to US National Atlas Equal AREA EPSG:2163
I've tried setting both layer and project CRS to the mentioned projection, but no avail.
Here's a screenshot + first bit of gdalinfo.
