How to Create a Cross Section in ArcGIS Using DEM
Learn how to create a cross section in ArcGIS using DEM data and the 3D Analyst Profile Graph tool. In this step-by-step tutorial, I show you how to create an elevation profile from a DEM, visualize changes in terrain elevation, and prepare the cross section for presentation and analysis.
A cross section/elevation profile is useful for understanding how elevation changes along a selected line across a landscape. In this tutorial, I demonstrate the process in ArcGIS using the 3D Analyst extension and DEM data.
-What You’ll Learn:
How to activate and set up the 3D Analyst extension in ArcGIS
How to add DEM data to ArcGIS
How to draw a line for your cross section
How to create a cross section using the Profile Graph tool
How to generate and interpret an elevation profile
How to copy and format the cross section for presentation
How to create a cross section using a different DEM
-Tools & Data Used
