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...

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....

UAV Sand Dunes

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...
