Species information was derived from hyperspectral imagery and then applied to the lidar point cloud for this image.

Fusing Data on Doomed Ash Trees

By using fused data gathered with lidar and hyperspectral imaging, a geospatial services company helped a large utility to identify 90% of ash trees with the potential to fall into their power lines—in a timeframe that wouldn’t have been possible without the use of remote sensing. By Ian Berdie, Zach Raymer, and Mia Chen Remote-sensing...

Assessing the Potential

UAS-based Topobathymetric Lidar Surveys Understanding stream channel and floodplain morphology is critical for a number of efforts—from hydraulic modeling and stream-restoration design to aquatic habitat assessment. These applications require description of conditions both inside the channels and in the adjacent riparian zones. Gathering these data has typically relied on individuals on the ground or in...

Aerial Imagery to the Rescue

Events in 2017 demonstrated without any doubts or reservations how vitally important georeferenced aerial imagery is in assessing damage and supporting relief efforts following a natural calamity. Last September, an impromptu consortium of companies in North America mobilized their forces and collected and analyzed mountains of data at near cost to help out in what...

Different visualizations of the same VNIR+SWIR hyperspectral image (of Wizard Island, Crater Lake, OR) draped over a lidar bare-earth digital elevation model. The variation in vegetation, snow, soil/geologic cover, and even water properties can be highlighted with different combinations of spectral wavelength images.

HSI on the Fly

One company details mapping applications of airborne hyperspectral imagery for agriculture, forestry, and resource mapping. By Patrick Burns and Scott Nowicki, PhD Remote sensing imagery has been collected with many different camera systems for many different applications over the past 50 years of the industry.  Visible remote sensing imagery provides interpretable information available to most...

Thermal Imaging Heats Up the Geospatial World

Thermal Infrared (TIR) remote sensing technology makes existing applications more cost-effective and creates new applications, including for the environment. News footage frequently shows a dramatic scene of a suspect hiding in the shadows on a pitch-black night. Despite the darkness, the subject glows white-hot in the video recorded from a police helicopter’s thermal infrared (TIR)...
