Absolute deformation can be inferred by assuming one area in the interferogram ( for example a point away from expected deformation sources ) experienced no deformation, or by using a ground control ( GPS or similar ) to establish the absolute movement of a point.

You " can " detect acceleration with relativity ( you can't distinguish absolute movement of any sort between two " inertial " frames, but you can between " accelerating " frames ), but, as Someguy1221 points out, you can't distinguish acceleration from gravity.

:A linear graph would show the absolute movement of the average while a Logarithmic scale, at every point along the scale, would show only the relative change of the average-a logarithmic scale makes a 1 % change the same " size, " throughout while a linear scale makes a 1 $ change the same " size " throughout . & laquo; Talk & raquo; 20 : 42, 11 May 2007 ( UTC)
