Digital Terrain Model Analysis (DTM) [ArcGIS Pro]


This program is designed to give an understanding of DEM and DTM, their use to describe the ground undulations. For you to learn the use to extract various terrain parameters such as slope, aspect, roughness and perform application analysis such as line-of-sight analysis and watershed structure generation.

The course further addresses the use ArcGIS Pro and ArcGIS Spatial Analyst tools to derive new data from an elevation raster. The results can be used to model and visualize the earth's surface, perform analysis, and support decision making for a variety of applications.

Targeted Groups:

  • Engineers
  • Architects
  • Anyone who has a desire to explore the application of DEM and DTM.

Course Objectives:

At the end of this course the participants will be able to:

  • Derive slope, hill shade, and aspect surfaces.
  • Identify locations in an area of interest that meet elevation, slope, and aspect criteria.
  • Generate contour lines to represent elevation measures on a map.
  • Create a viewshed raster.
