Imagery Fully Integrated

It’s difficult to believe there was a time with parallel worlds of GIS and imagery. Now they’re tightly tied and getting more tightly integrated.

Canada’s Costly Fort McMurray Wildfire

The Fort McMurray wildfire, which was first reported on May 1, 2016, and not declared under control until July 5, 2016, destroyed more than 2,400 homes and buildings and forced the evacuation of 80,000 people in Alberta, Canada. Although no one died directly from the fire, it is expected to be one of the most-expensive natural disasters in Canada’s history, with insurance and firefighting costs expected to reach up to $5 billion, a figure large enough to negatively impact the country’s overall economy.

Small Satellites, Big Market: Boundaries to Space-Based Earth Observation Rapidly Disappearing

For what SmallSats lack in size, they more than make up for in quantity and breadth of coverage, and that goes beyond just their physical dimensions. Along with unmanned aerial systems (UASs or drones), SmallSats (which have several related subsets such as cubesats, nanosats, microsats and others) seem to dominate headlines and conversations in Earth-observation industries and media.

Earth Observation and Big Data: Creatively Collecting, Processing and Applying Global Information

To help Earth observation (EO) at Big Data scales, teams outside GIS and remote sensing are increasingly rising to the challenge to understand data sources, management and processing.

NGA Director Cardillo Declares GEOINT on the Rise

The agency I’m privileged to lead celebrates a major anniversary this fall. It’s been a remarkable 20 years—from NIMA stand-up to NGA transition to the GEOINT Revolution. And I can proudly—and confidently—say that GEOINT is on the rise, more relevant than ever to our customers today and poised for a tomorrow that’s filled with possibility.

Are UASs More Like PCs or Macs?

Because I’m a land surveyor by background, I keep thinking it’s the UAS that’s important; the manufacturer matters, in the same way the choice of total station or laser scanner often comes down to a preference for Leica or Trimble. But Airware (and other firms) argue that UASs are more like a commodity, and that the real value of UASs for businesses lies in the systems installed on the vehicle.

Satellites Find Source of Aurora Explosions

An international team led by Hiroshi Hasegawa and Naritoshi Kitamura (ISAS/JAXA) analyzed data taken by the U.S.-Japan collaborative GEOTAIL mission and NASA’s MMS satellites, finding that the interaction between the magnetic fields of Earth and the Sun, or more precisely the phenomenon known as “magnetic reconnection,” can feed aurora explosions.

DOI, UAS Industry Partnering to Reduce Firefighting Interference

To address the growing problem of unmanned aircraft systems (UASs) impeding wildland firefighting efforts, the U.S. Department of the Interior and industry partners activated a prototype warning system that provides real-time alerts and geofencing alarms to prevent drone pilots from interfering with firefighting operations.

Tonga’s Beautiful Beaches, Reefs and Lagoons

The Kingdom of Tonga in the southern Pacific Ocean has a population dispersed across 36 of its 169 islands, but about 70 percent of the people live on the main island captured in this image from the European Space Agency (ESA) Sentinel-2A satellite.
