Return of the DEM

By Wes Jones

Five days of Halloween

Day 5

In 2021, the DEMentor was rasterized. Now it is back, this time in ArcGIS Online.

ONE: Go to ArcGIS Online and add the terrain service.

TWO: Flip the colour ramp and adjust the gamma, min and max values.

THREE: You have a DEMentor.

FOUR: Lock the door, run to your nearest graphic editor, and make a movie poster (or three).

Be sure to catch the sequel. Twice the height – twice the DEM!
