Re: [otb-users] Simple geometry tools in OTB?

[Guillaume Pasero]

Hi, Would this polynomial transformation be : a new type of sensor model (to be used during ortho-rectification) ? or an arbitrary transform that can be applied to any image (such as the rigid transforms) ? The polynomial model is a particular case of rational model, maybe setting the denominator coefficients to [1,0,0,...,0] will do the trick.

Is it possible to apply such a polynomial using x,y,z coordinates as suggested in Pala, V., and X.

The later is a simple approach that works well with relatively coarse imagery (i.e. 10-30 m resolution).
