Please download this CHaMP Survey, which includes the 'Survey' and associated surfaces of roughness, interpolation error, 3D point quality, interpolation error and point density. Please attempt to run the 2-input, 4-input and 5-input FIS error models in Bangen et al. (2015) and prepare a brief write up describing the differences you see in each output. Which would you use, why?

Note: there is a tutorial for this exercise, but you need to do the interpretation on your own.
Upload a zip file of your GCD project containing the error models. Upload a PDF of your write-up.
