Infrared Aerial photography

Infrared aerial photography can be used to document changes to the environment, health of forests, wetlands, bays and oceans. It can also be used to document and monitor such items as damage to roofs, the tracking of dairy farm out flows, pinpointing the source of, and monitoring, insect or disease infested vineyards, or sites contaminated by toxic chemicals.  These changes can affect small rural farmers and business owners, and these photos can help them prepare for it.
