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...
