Thermal Imaging is the conversion of radiated or reflected heat into real-time pictures or images. A thermal image is an analogue pictorial representation or visualisation of temperature differences.

All objects above absolute zero (-273 degrees) emit radiation, some of which is infra-red. Depending on temperature and emissivity, most objects in the world can be thermally imaged.

Horton Levi specialises in all forms of thermal imaging; ground, mast and aerial surveys with optional G.I.S. integration, systems engineering and research.
