Jeff Thurston — "Geographic Information Systems (GIS) are centrally connected to sustainability issues. They are integrator’s of spatial information which originates from technologies and systems used to monitor, measure, map and model environments and systems related to sustainability issues."

Matt Ball — "GIS projects have already contributed a great deal toward understanding and quantifying what is meant by sustainability, and will continue to contribute to our understanding of Earth systems interaction. But to date there hasn’t been much geospatial community or GIS vendor action to create multidisciplinary workflows or toolsets that specifically address sustainability."

Jeff Thurston — "We need to explore these possibilities more. We need to understand that what we think as professionals may need to be adapted for consumption and understanding by others. Gaming is a route into the process of change – of understanding communities and relations between people. "

Matt Ball — "The considerable graphics demand of gaming software has spurred advances in computer hardware that have in turn increased the speed and clarity of displayed graphic information, paving the way for the display of real-time and realistic geographic information."

Jeff Thurston — "Traditionally DTM have been used to build elevation models of the Earth’s surface. They are 3D in nature and thus lend themselves to several important uses. Today, the idea is to build valuable products upon DTM, extending their usefulness, but also addressing real issues that incorporate other spatial information. The link of DTM Surface - Processes - Other Spatial Data is critical to understand."

Matt Ball — "A digital elevation model (DEM) represents the elevation of Earth’s surface, including features (vegetation, buildings, etc.). A digital terrain model (DTM) provides a bare earth representation of terrain or surface topography. Both are highly useful data sets for visualizing our planet for scientific and commercial landscape study. With each technological advancement, the digital elevation models have improved in accuracy, resulting in a much more useful model of the Earth."
