Drones Serving People


Hover Solutions is equipped with sensors capable of sampling wavelengths outside of the visible spectrum. In 2018, we added two new multispectral cameras to our fleet: The FLIR Vue Pro R, and the Micasense RedEdge-M.


The FLIR Vue Pro R is a 30Hz thermal imaging camera optimized for use on UAVs. We currently carry it on the 3DR Solo drone with a 3-axis stabilized gimbal.

This camera allows us to tune its internal settings to optimize radiant heat readings in a given set of atmospheric conditions, which leads to more accurate contrast and temperature readings. The Vue Pro R is also radiometric, meaning it can perform spot and range temperature readings in real time to an accuracy of about 5 degrees F.

Drones are an asset to a thermographic imaging workflow, allowing operators to obtain readings at optimal angles to capture radiant heat. With a drone, thermographers take non-contact heat readings without ever having to set foot on a roof.

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 imagery 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.
