Anyone ever have to make a fake hill slope? or a fake digital elevation model (DEM)? What are the best methods for doing so?
For more specifics, suppose I wanted to make a fake hill slope, that was 200m wide by 300m long. If I pick a stating height of 150m and an end height of 100m. How should I go about generating this hill slope? What tools (R, ArcMap, etc...) would be the best method for generating such a hill slope? Do any tools allow for random variation of the elevation values across the DEM (height and width) while still maintaining the slope value (or range of slopes) I am shooting for?
Asked another way, how do I create a 3D surface that is reminiscent of a real hill slope?
WhiteBoxDev's answer below is pretty close to being the answer I am shooting for. My only additional questions relate to randomly altering the elevation of the hill slope (perhaps with a random error?) to make it more realistic - and not perfectly smooth.
