Multi-spectral imaging collects data from discrete bands of the electromagnetic spectrum and can be used to determine characteristics of the subject from the unique response. Unlike traditional “color” imagery, which collects three, wide bands of light (red, green, and blue), multi-spectral imagery generally collects between six and thirteen individual bands with narrow bandwidths. This allows the user to view each wavelength individually or combine wavelengths in specific ways. The wavelength of mulit-spectral data typically spans from the ultraviolet (UV) to longwave infrared (LWIR) depending on the intended. This methodology includes infrared bands (also known as thermal, IR, or “heat mapping”) can be used to determine temperature variations across a site or object. The perspective gained from this innovative technology can rapidly communicate critical information to project managers interested in better understanding their project. Through high quality data capture and processing, orthomosaics from thermal imagery can be interpreted and put into action immediately.
This technology allows for a deeper understanding of the environment by manipulating individual wavelengths of reflected light, often outside the visible spectrum.
When combined with high-resolution RGB imagery or LiDAR, a complete 3D multi-spectrum model can be created. Using a combination of sUAS LiDAR and orthophotography as well as multi-spectrum imaging, Elevate can create 3D models of variations within a site or area. This allows for a more holistic assessment of the site to be conducted. Elevate has used this methodology on a number of environmental and critical infrastructure projects.
- Thermal inspections of roof, solar, and utilities (See example of this in action here)
- Soil and rock composition
- Vegetation health for agricultural management or environmental restoration (see example of this in action here)
- Identification of potential contaminants
- Springs and groundwater seeps
- IR building enclosure investigations
