There are lots of affordable UAVs for hobby use. Does anyone have experience with using them to create aerial maps? What UAV, camera, and gyroscope hardware do you use, and how do you create georeferenced maps from the images?
there are a large community of diy drones at: http://diydrones.com/
But making georeferenced images or IR is mayor step, at least as remote sensing requires
There are several DIY techniques with several issues.
One option could be flying twice the same area with a commercial camera with and without an IR filter and then combining bands with image processing sw. In this case you have to take into account all the issues match gemetrically the two acquisitions. Another option could be to use a commercial camera with two lenses, in this case one will be equipped with the IR filter.
In the past, I have worked with georeferenced multispectral imgery (for precision agriculture & forest management applications), acquired from aricraft using the sensor package from Geovantage LLC, a commercial provider:

I am not sure if this company sells / leases their package any longer.
Hi, we have been using the ebee UAV from sensefly in Antarctica, both with RGB and NIR camera. The results are excellent and they also sell the bundle with an orthorectification package.
Here at USP, Brazil, we have also been using Sensefly eBee UAV for flying eucalyptus plantations and detecting problems in city pavements using both RGB and NIR cameras included in the box.
