sm_compare¶
Compare two shakemaps.
This program is to quickly make maps comparing two different shakemaps. Since the main goal is to compare across maps using ShakeMap 3.5 and ShakeMap 4.0 the arguments are paths to grid.xml files.
Note that ratios are grid1/grid2 and differences are grid1 - grid2.
usage: sm_compare [-h] [-i IMT] [-o OUTPUT] [-n] grid1 grid2
