Hold on folks. First, the field of thermal imaging is changing day by day. Last year Maps Made Easy said it wasn't able to make good maps with the lower resolution XTs, but now check out Tag Pilot, specifically the thermal tagging features.
Thermal Tagging From what I can determine you will need one of the radiometric models.
From their marketing description:
"One of the most useful features of Tag Pilot is the ability to detect and document thermal signatures that fit certain criteria. This has huge applications such as detecting a missing person in Search and Rescue operations or mapping out active wild fire lines in low visibility (smokey or night time) situations. Pressing the "FLIR XT Setup" button will open the settings panel for the thermal operation specific setup items. Automatic Thermal Tagging (Auto Tagging) uses the definition of the size and temperature of the object(s) to be detected to analyze the thermal imagery and highlight areas of interest."
For MBA thinking folks, this appears to be a top-down approach to thermal mapping. "I am doing search and rescue. Show me the spots where a missing person might be; Temp: 27 C to 37 C - Size: .4m to 2m" On the other hand a field map might be a "bottom-up" approach: "Build me a map of the field and let me see what's there."
Check out Tag Pilot in the App Store and Maps Made Easy. It has setups for the XT, and I bet if you contact them they will happily send you some sample files and more info. Tell us how this works out for you.
