Pix4D alternative?
Podrock have you used any of this stuff on opentopography? I'm interested how it compares to Pix4D. I'm wanting to start capturing topographical imagry using a quadcopter, but Pix4D has a pretty steep entry point. Looking at other options to explore the viability before spending the big bucks. Outputting geotiffs and 3d meshes and pointclouds are what I'm most interested in.
