These files are actually text files. If we open up the one that we have here, under exercise files, raster data with workbench, I'm just going to open it up with notepad. I'll right click, open with notepad. You'll see, it's basically just a big text file with X, Y and elevations in it. And it's in meters normally. This one happens to be in UTM zone, 11 meters.
