Interactive Online Quick Terrain Modeler Demonstration

To make the most of your trial period, we strongly suggest an interactive, live, online demonstration of the Quick Terrain Modeler. While the Quick Terrain Modeler is easy to use, a few basic tips from us could help you get started very quickly. In addition, if you would like us to work with your own data during the demonstration, we can accommodate you by providing our FTP site information. Once you upload your data to our site, we will be able to work with it during our demonstration.

A live demonstration consists of Applied Imagery controlling the Quick Terrain Modeler from our office, the audience viewing the demonstration on their computer (or multiple computers), and a conversation via telephone. We can adapt to the specific features you would like to see, whether it is building models, analysis tools, overlaying imagery, or any other topic of interest. The online demonstration is free and usually takes 60 to 90 minutes. To schedule a demonstration, please send an e-mail to info@appliedimagery.com.
