The website states:

"As the fields of digital mapping and geospatial analysis continue to grow, the use of 3D data is becoming more widespread. One of the most common types of 3D data is a digital elevation model, or DEM. In this Webinar, we'll talk about what DEMs are and how they differ from other types of spatial data. We'll also look at some of the sources of DEM data, their quality, and how they are generated. Lastly, we'll look at examples of how you can use DEMs in sophisticated geospatial analysis to solve real-world problems."
