Varres - Variable Resolution Interferogram sampler

Varres is a variable resolution interferogram sampler that implements a curvature-based quadtree like resampler for reducing unwrapped interferometric phase to a smaller subset of observations. Using the reduced set of observations which represent the non-redundant observations in an unwrapped interferogram in modelling significantly decreases computation cost. Moroever, it can reduce bias due to uneven distribution of coherent samples in the unwrapped interferogram. The package is based on the work published in

Coseismic Deformation from the 1999 Mw 7.1 Hector Mine, California, Earthquake as Inferred from InSAR and GPS Observations, M. Simons, Y. Fialko, and L. Rivera, Bull. Seismol. Soc. Am., 92, 1390-1402, 2002. [PDF]

The original matlab package has been extended to include support for using a predefined map for resampling and estimation of an approximate covariance matrix for the samples.
