I was looking at this post http://diydrones.com/profiles/blogs/maps-made-easy and am looking to get into mapping with an Iris and currently have a GoPro Hero3+ Silver camera.
I am thinking of either changing the lens to remove the fisheye or distortion, or buying a Cannon camera to use CHDK.
Here is a blog post about about changing your GoPro lens .
I am leaning towards buying a Cannon camera because I think you have better control over the images with CHDK and no distortion. This Cannon SX 230 HD has built in GPS.
Anyone have any tips on mapping?
How do you get your pictures to overlap?
What is the best height to fly at?
Can anyone point me to a "mapping 101 for drones" webpage ?
