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)...

An ICIMOD team manually validated the accuracy of the 2011 classification maps.

A Crowning Achievement in Nepal

An ICIMOD team manually validated the accuracy of the 2011 classification maps. Pairing satellite imagery with advanced object-based image analysis helps people in Nepal better manage vital resources. For decades, the high-mountain regions of Nepal have been caught in a perpetual catch-22. The small populations of these remote, isolated areas depend nearly exclusively on local...

A portion of a roadway that’s subject to flooding was scanned to perform drainage analysis as well as to map the existing conditions.

Prepping for El Niño

Above: A portion of a roadway that’s subject to flooding was scanned to perform drainage analysis as well as to map the existing conditions. As the severity of weather increases, so do the benefits of high-definition laser scanning for asset management and damage analysis. Editor’s note: Improvements in, and availability of, tools and resources for precise...
