| Jun 7, 2019 at 20:39 | comment | added | James R. | That was it! I set the CRS to US National Atlas Equal Area, and everything came up perfect. Thank you so much! | |
| Jun 7, 2019 at 20:34 | comment | added | csk | If that doesn't work, try the Albers Conical version (make sure it's in an Albers Conical Equal-Area CRS). | |
| Jun 7, 2019 at 20:30 | comment | added | csk | "The Grayscale United States Shaded Relief – 200 Meter Resolution map layer is available in both a Lambert Azimuthal Equal-Area projection and an Albers Conical Equal-Area projection." It looks like you have the Lambert Azimuthal Equal-Area projection version. Try setting the CRS (in the layer properties) to a CRS in the "Lambert Azimuthal Equal-Area" section of the CRS selector. EPSG:2163 (US National Atlas Equal Area) sounds like a reasonable one to try. | |
| Jun 7, 2019 at 20:21 | comment | added | James R. | I remove/added all the layers without making any changes in the CRS, but I'm still getting same results. Also, didn't find anything in the metadata of the relief map. Anything else I can do? | |

| Jun 7, 2019 at 20:02 | comment | added | csk | If you did change the CRS (in the layer property) of any of these layers, remove that layer from your map and add it back in. This will hopefully reset the layer back to its intended CRS. Also, look up the metadata / layer description of the relief map and see what CRS it's supposed to be in. Then see if you can find a pre-loaded CRS to use for that layer. | |
| Jun 7, 2019 at 20:01 | comment | added | csk | The main CRS of your map doesn't matter for this purpose. As long as the CRS of each layer is correctly assigned, QGIS can display them so that they line up. This feature is called "on-the-fly reprojection; in QGIS 3 it happens automatically, and in earlier versions you could turn it on and off through project properties menu. If you have OTF reprojection turned on, the problem might be that one or more layers has an incorrect CRS. The most common cause would be if you (incorrectly) changed one of the layer's CRS through the layer properties. Or maybe the "generated CRS" is incorrect. | |
