Thermal & Multispectral Imaging

Hover Solutions is equipped with sensors capable of sampling wavelengths outside of the visible spectrum. In 2019, we’ve added a certified thermographer to our staff.


The FLIR Vue Pro R is a 30Hz thermal imaging camera optimized for use on UAVs. It’s the base camera on the DJI Zenmuse XT thermal system for the Inspire 1 drone line.

By controlling for atmospheric and surface conditions, we can take both qualitative and quantitative infrared emissivity readings to check for pooling/subsurface water, mechanical stress, electrical malfunctions, missing or poor insulation, and other sources of thermal anomalies.

Drones are an asset to a thermographic imaging workflow, allowing operators to take non-contact heat readings without ever having to set foot on a roof.

Our on-staff thermographer is certified by the Infrared Training Center and will plan the mission, execute the data collection, and interpret the data according to your needs.

Hover Solutions gathers multispectral images using the MicaSense RedEdge-M, which uses a global shutter to capture light in five different wavelengths: Blue, Green, Red, Near Infrared (NIR), and Red Edge.

Because it captures five bands of light, we use images from the RedEdge-M to construct four different map products:

  • A true-color orthomosaic from the red, blue, and green bands
  • A digital surface model using photogrammetry
  • A Normalzied Difference Vegetation Index (NDVI) map derived from the NIR and Red values
  • A chlorophyll map derived Red Edge band values.

Images captured with the RedEdge-M are calibrated against a radiometric reflectance target, and encoded with offsetting information from a top-mounted sunlight sensor to account for changes in solar lighting at the moment of capture.
