Kim Buike, Depiction Board Member and Instructor teaching an on-line Masters course on Depiction Mapping Software for California State University Long Beach, has prepared a tutorial for his class on how to find, download and import into Depiction 10 meter elevation data.  The elevation data currently available through the Depiction Quick Start is 30 meter data.  Having higher resolution elevation data will make the various simulations that Depiction can perform much more accurate.  You can find the tutorial here.
