I'm a very new QGIS user and no GIS expert. I am having trouble getting jp2 images to align with a vrt raster I've created from SRTM images.
What I'm trying to do: Overlay SRTM data with corresponding jp2 images I've downloaded from USGS NAIP data. I'm using the CCM data in .jp2 format. Ultimately, I want to merge the images and cut them to the exact size of the SRTM vrt I've created. I then need to rescale the pixels and output them as a series of .bmp tiles for an aviation simulator scenery.
What I'm having trouble with: The jp2 images open in QGIS but although I specify WGS 1984, they are placed very far away from the actual lat/lon they are supposed to be at.
I know the data is in the jp2 files to do this, but there's something I'm missing about the jp2 format and how to get it to show up at the right lat/lon. I've searched but mostly find answers about manually georeferencing an image. I don't think that is necessary because I downloaded these images from the USGS using lat/lon coordinates as bulk files.
Using get info from the file, I get the following:
