I have used helicopter mounted FLIR (JetRanger, Messerschmidt 117, Kaman SH2) with little success. This usually due to the sameness of the area and or presence of heavy woods and trees.
Good images on film or disk require the services of a photo interpreter, not easy to find even in the military. The desk top computer software can help if you have it, a high speed graphics machine and the right periperals to get the image in and out. (Anybody got a spare Silicon Graphics 8x8 server to loan us?)
If you have access to a military photo recon outfit use them.
Hand held optics are about useless in a light aircraft and definitely useless in a helicopter without stabilization
The new gyro mounts for the TV news cameras could produce some very good images with long lenses and low light levels or amplifiers ....
Will try to follow up on the news idea.
