Do you mean geo tagging thermal photos? if so here is one place I have been looking at. Still waiting for a reference from them before I move on it. sUAS Thermal Vision|Gimbals for FLIR|sUAS.com
I am selling a modified zenmuse x4s camera to capture NIR imagery to generate NDVI indices. This camera was bought from aerial media pros (https://aerialmediapros.com/store/agriculture-ndvi-ndvi-cameras) which are modified by Nolan and the team at Peau Productions/MAPIR. It also includes the necessary Calibration target that is an additional $260. It's plug and play with the Inspire 2. It doesn't have many hours on the camera and it looks unused. I upgraded to a Sentera camera that captures RGB and NIR data simultaneously. Looking to get $1500 for both camera and calibration target. PM if interested or text 804-248-0959
