ENVI Helps Researchers Monitor Ecological Integrity
Scientists concerned with changes in our ecological systems continually explore new ways to depict important study results which can be instinctively understood by their audience. Static maps and 2D presentations were for decades the only methods for scientists to present results of land studies and scientific research projects. Increasingly, scientists need innovative ways to communicate findings quickly and accurately to policy makers and the general public.
Photorealistic visualization is a way to represent findings by manipulating data to create 3D, dynamic presentations. In an effort to monitor the ecological integrity of protected land areas in Canada and present results, several agencies, including the University of Ottawa's Laboratory for Applied Geomatics and GIS Science in the Department of Geography, have joined forces in a Government Related Initiatives Programme (GRIP)*. GRIP strives to increase the public’s awareness of Canada’s National Parks via community outreach and education. Team members use photorealistic visualization to help people discover the natural beauty of Canada’s National Parks and understand factors that affect its ecological integrity.
GRIP researchers use remotely sensed data and ENVI to perform topographic data manipulation, Earth observation data sourcing, data pre-processing, key environmental feature identification, and photorealistic visualization. In a project that won second place in RSI’s (now Exelis Visual Information Solutions) International ENVI Application Challenge, Dr. Mike Sawada and Zoran Reljic of the University of Ottawa, sought to demonstrate ENVI’s superior spectral processing capabilities by creating dynamic presentations of Auyuittuq National Park in Nanavut, Canada. The team used a host of built-in ENVI routines to produce 3D, photorealistic visualizations of the park to show the basic landscape and ecological changes over time.
- Present data and research findings to their audience in a realistic manner.
- ENVI has the tools and functionality to allow researchers to create the state-of-the-art visualizations.
- Other tools do not provide the breadth of functionality in visualizing data.
