Analysis of digital elevation models in Erdas Imagine

In this session i am showing you, how to analyze a DEM (digital elevation model) in Erdas Imagine, esp. calculating slope, aspect and shaded relief.

In this session i am showing you, how to analyze a DEM (digital elevation model) in Erdas Imagine, esp. calculating slope, aspect and shaded relief. Additionally you will see a solution on how to create thematic rasters using "conditional" statements and the Modeller of ERDAS Imagine.
