- A digital elevation model, or DEM file, is considered…a raster file, but really contains points…at regular intervals that, most importantly, have…elevations at those points.…Let's add a couple of DEM files to our current…QGIS session.…Browse to your Raster folder, double-click…on the first DEM, and double-click on the second.…It will automatically draw the DEM files.…Now, these are showing from black to white,…a range of elevations, of what are in the file.…
So for example, the first file, this one here…on the left, goes from zero to 313.…And these are in meters, so that is from…zero to 313, that's almost 1000 feet.…So that's the range, from sea level to 1000 feet,…or 313 meters.…The second one shows from zero to 81 meters…above sea level.…So there's no files higher than 81.…So let's just change a few of the styles…so this map looks a little different.…So first of all I'm going to pick on the right-hand side…double-click on it, the one with zero to 81.…
And we're going to change the style so…instead of the Max being 81, we're going to…
