I am using QGIS 3.03 Girona and trying to process the CONUS 2016 NLCD (Continental US 2016 National Land Cover Database) 30x30 raster data provided by the MRLC viewer. I downloaded an area with the boundaries W078 N40 E076 S38 and would like to use this landcover data with Open Street Map vector data and SRTM-1 elevation height maps. That data comes in the WGS84 projection while the NLCD data comes in its own projection:
The CRS given by QGIS is:
- Generated CRS (+proj=aea +lat_1=29.5 +lat_2=45.5 +lat_0=23 +lon_0=-96 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs)
However, I have been having trouble reprojecting the data. If I set WGS84 directly by Set Layer CRS, the raster layer disappears entirely. Zoom to layer shows its now projected fine but massively zoomed out: notice the coordinates at the bottom - thats in degrees!
If I save as with WGS84 set, I get the same (except in black and white).
If I use the warp tool to reproject as WGS84, I get the very same that I started with (the image on top of the OSM data correctly scaled, but slanted over).
Does anyone know how to project it properly?
It should cover the exact same area as my four SRTM-1 elevation tiles.
