Re-imaging Hells Canyon
A geospatial company helps prepare for an environmental impact statement by scanning and orthorectifying historic imagery. Hells Canyon, North America’s deepest river gorge, encompasses a vast and remote region with dramatic changes in elevation, terrain, climate, and vegetation. Carved by the great Snake River, Hells Canyon plunges more than a mile below Oregon’s west rim...
Mapping the Pennsylvania Lake Erie Watershed
Imagery was collected along 77 miles of shoreline to provide a better understanding of Pennsylvania’s natural resources. By Brian Stevens The Pennsylvania Lake Erie Watershed is a substantial part of the world’s largest surface freshwater system, the North American Great Lakes. The watershed is 512 square miles, consisting of 15 major sub-watersheds. It’s estimated that...
Remote Sensing in Yellowstone Park
A consortium demonstrates the value of integrated remote-sensing technologies for studying and monitoring the impacts of climate change using the northern range of Yellowstone National Park as a testing area. By Dr. Olaf Niemann, Dr. Robert Crabtree, and David Brown In 2014, a consortium between environmental scientists and an airborne remote-sensing company was awarded funding...
Workflow in Constructioneering
To remove workflow barriers among surveying, engineering, and construction, Topcon Positioning and Bentley Systems are teaming up. Compartmentalization in AEC workflows is a universal curse, with individual segments in design and construction often operating more like discrete enterprises than integral phases. All too often, legacy processes are plagued with a series of fits and starts....
UAS Survey of the Great Sand Dunes
The Great Sand Dunes National Park and Preserve is located in South Central Colorado and contains the tallest dunes in North America, spread across 30 square miles. It is an amazing destination, one that I first visited when I was 18 years old and have re-visited innumerable times since; I simply never tire of its...
Disparate Data for Marine Life
Remote sensing data helps to inform ocean planning for energy development around the main Hawaiian islands. Using remotely sensed imagery to map physical and biological patterns in the marine environment enhances our ability to understand how environmental conditions change over broad spatial scales (10s to 100s of kilometers) and temporal scales (years to decades). These...
