| Jun 4, 2018 at 4:59 | comment | added | Carol Lewis | i think your photo is just a part of Florida. It's a tile. You have to download the others tiles to cover up the entire shapefile. | |
| Jun 4, 2018 at 4:02 | comment | added | user2856 | What you show in your screenshot is correct, I think I found the DEM you downloaded - i.sstatic.net/xPUp2.png. You have a DEM tile that covers only a small part of Florida, it's a section of a larger DEM. If you want a DEM that covers all of Florida, you need to download more tiles and mosaic them. | |

| Jun 4, 2018 at 3:22 | comment | added | Jon | Are you sure you downloaded the whole state's DEM? Many of the DEM products are served as tiles. As Luke said, a picture would be very helpful. | |

Your question is very unclear. Can you edit it and show a picture of what you mean and also include gdalinfo report (or the QGIS layer metadata as text) for the raster DEM and ogrinfo report (or the QGIS layer metadata as text) for the shapefile. If you have changed the projection/CRS of either, include that information.

| Jun 4, 2018 at 2:30 | comment | added | Vince | Welcome to GIS SE. As a new user, please take the Tour. You'd have to make raster pixels infinitely small to follow an angled line (which would mean the image would be infinitely large). Vector GIS exists so that you don't need to make that choice. You could certainly apply a negative buffer to the vector layer, but doing so would corrupt it, topologically, so it no longer represents what you claim it does. Traditionally, the way to present this is to place the vector on top of the raster (potentially with transparency). | |
