Hyperspec SWIR Gets UAV Wings!

Posted by Christopher Van Veen on Thu, Sep 14, 2017

Remote sensing with hyperspectral sensors is  a combination of several elements: an imaging spectrometer and a fast data processing system to acquire and analyze spectral and spatial data. For remote sensing missions such as crop disease or invasive species detection, the spectral range of most interest is the visible-near-infrared (VNIR) from 400-1000nm.

The Eyes Have It...But Not Always

Posted by Christopher Van Veen on Thu, Apr 13, 2017

Humans have a marvelous ability to see and identify objects within what is called the visible range of the electromagnetic spectrum. That starts at roughly 380 nanometers and goes up to around 700 nanometers or so.

Data Fusion: A New Capability for the Remote Sensing Community

Posted by Christopher Van Veen on Tue, Mar 01, 2016

We’re seeing a tremendous increase in the number of airborne deployments for our hyperspectral imaging sensors. To a large degree, the trend toward smaller and more affordable UAVs is giving the remote sensing community more flexibility to undertake more missions to capture meaningful environmental data. From wine-grape vineyards in northern California to coffee bean plantations in South America, the precision agriculture community is embracing packaged ‘UAS’ offerings that combine a UAV matched to the payload it needs to carry.

Headwall Delivers Micro-Hyperspec® Sensors to Columbia University

Posted by Christopher Van Veen on Thu, Oct 09, 2014

High-performance imaging sensors on small, commercial UAS will assess ocean and sea ice variability in Arctic zones

FITCHBURG, MA - OCTOBER 9, 2014: Headwall Photonics has delivered two high-performance hyperspectral imaging sensors to Columbia University as part of its Air-Sea-Ice Physics and Biogeochemistry Experiment (ASIPBEX). ASIPBEX is part of a larger international collaborative investigation of Climate Cryosphere Interaction with colleagues from Spain, Germany and Norway. This crucial remote-sensing project will use a high-endurance unmanned aircraft system (UAS) to investigate climatological changes present in the Arctic Ocean around Svalbard, Norway. The instrument payload comprises two Micro-Hyperpsec sensors; one will cover the Visible-Near-Infrared (VNIR) range of 400-1000nm while the other will cover the Near-Infrared (NIR) range of 900-1700nm. Together, the sensors will be crucial in detecting indicators of sea ice physics, solar warming and global carbon cycles.

Smaller, Lighter, Better: Hyperspectral on UAVs

Posted by Christopher Van Veen on Fri, Aug 08, 2014

At Headwall we've been busy listening to the market. When it comes to airborne remote sensing, the market is telling us that they favor UAVs (unmanned aerial vehicles) of all kinds: fixed-wing, multi-rotor, and so on. There's no end to the number of companies producing UAVs globally. Because many UAVs produced today are very small and affordable they are 'within reach' of those with even modest means. Universities represent one key market where the use of UAVs is rapidly increasing. Full of scientists and research departments, universities around the globe see these small and light UAVs as a perfect platform from which to launch their exploratory studies. They are affordable, easy to assembly and transport, and (especially with multi-rotor models) can take off and land within a very small footprint.

Hyperspectral Takes Wing Over Ontario!

Posted by Christopher Van Veen on Thu, May 01, 2014

Under cloudless skies in Ontario recently, Headwall achieved a very notable milestone: we became the first to fly both hyperspectral and LiDAR aboard a small, fully integrated handheld UAS. The test flights not only verified the reliable airworthiness of the system but also the ability to collect valuable hyperspectral and LiDAR data in real time.

UAVs and Hyperspectral Imaging Unite

Posted by Christopher Van Veen on Tue, Mar 25, 2014

One of the things we’re seeing at Headwall is the proliferation of airborne applications. Multispectral suffers a bit with respect to hyperspectral (a handful of bands versus hundreds), which is why hyperspectral is winning the day.

Headwall's Field-of-View Calculator

Posted by Christopher Van Veen on Mon, Mar 17, 2014

When it comes to hyperspectral imaging, it isn’t always about the hardware. Before users even get to the stage of specifying a sensor instrument, they need to ask a few questions:

Hyperspectral Sensors for UAV Applications

Posted by Christopher Van Veen on Wed, Feb 19, 2014

The scientific research community is beginning to understand and embrace hyperspectral imaging as a useful tool for a few primary reasons. First, sensors are more affordable than ever. Originally conceived as multi-million-dollar ISR platforms for defense applications, hyperspectral imagers have been successfully ‘commercialized’ over the past few years. Scientists typically embracing RGB or multispectral technology before can now acquire hyperspectral sensors at affordable price points.

Headwall Remote Sensing Capabilities Seen “Down Under”

Posted by David Bannon on Wed, Jul 31, 2013

This past week, Headwall remote sensing team finished a productive week Down Under at the International Geoscience and Remote Sensing Symposium (IGARSS) in Melbourne, Australia.  The conference, organized by the IEEE, comprises a ‘Who’s Who’ across the global remote sensing community. But curiously absent were representatives from the United States, probably reflecting the topic du jour: sequestration. Imagine holding a geo-spatial and remote sensing conference and no one from NASA was able to attend?
