I created and presented this poster featuring LIDAR Color Shaded Relief model of Bouctouche / Shediac area of New Brunswick at the 2004 Geotech event that was held in Toronto.
Digital Terrain Modeling is the process of simulating or representing the relief and patterns of a surface with numerical and digital methods. It has always been an integral component to geology related fields such as geomorphology, hydrology, tectonics and oceanography but over the past decade has also become a major component to non geophysical applications such as GIS modeling, surveying and land use planning.
Terrain Models are derived from data represented by digital elevation models (DEMs) and can include shaded relief models, slope and aspect models, perspective scene generation, and drainage basin analysis (and other models).
Below are a few 3D Toronto images from a demonstration that I gave comparing Esri Arc Scene with FLY in PCI Geomatica. I generated the digital surface model (DSM) from some demo LIDAR all hits data that we had. The coverage area is for a small portion of downtown Toronto centered around Toronto City Hall.
