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...
Canadian Hydrographer Certification Scheme
Submitted by Bruce Calderbank, FRICS, CLS, P. Eng. The Association of Canada Lands Surveyors (ACLS) has developed a certification model for hydrographers and offshore surveyors that has been officially recognized by the IHO/FIG/ICA International Board of Standards and Competence for Hydrographic Surveyors and Nautical Cartographers (IBSC) in April 2016 and is now ready to receive applications....
Deep-sea Mobile Mapping
We’re all familiar with lidar-based mobile mapping from ground vehicles, and most of us are aware that aerial lidar is being used effectively to do shallow-water mapping along coastal and riverine projects. Deep-water lidar mobile mapping from an ROV? Well it’s a first for me. Most all of the subsurface surveys I’ve read about were...
40 Under 40, 2017: Erika Woolsey
CEO AND CO-FOUNDER OF THE HYDROUS CALIFORNIA, USA AS ERIKA WOOLSEY PROGRESSED through her academic and scientific career, she felt something was missing. She said, “[My] message was reaching a limited group of people who already understood the problems.” What was needed to protect and preserve critical ocean habitats was a broader inclusion of stakeholders,...
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...
