Color Shaded Relief Models

A color shaded relief (CSR) utilizes chromo stereoscopic techniques to help emphasize the depth of the Z dimension from traditional shaded relief models that already portray the presence of an elevation difference. Using carefully edited …

Digital Terrain Modeling

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).

3D Flood Modeling with LIDAR

The main goal of this project was to generate flood maps and DEMs with better than 30 cm vertical accuracy for the coastal area of southeastern New Brunswick.

RADARSAT Fine Mode Imagery

This is a poster of RADARSAT fine mode imagery of Nova Scotia that I created for a presentation at COGS in 1999.

RADARSAT fine modes - map of Nova Scotia

RADARSAT Fine Mode images are intended for applications that require the best spatial resolution. The azimuth resolution is 8.4m for all 5 fine modes and the range resolution varies from 7.1m (F%) to 8.3 (F1). Incidence angles range from 37 degrees to 48 degrees. The Fine mode images in the seamless RADARSAT Nova Scotia mosaic poster above include Digby, Wolfville, Truro, Cape Smokey Area, Brookfield and Halifax.
