MB-System is an open source software package for the processing and display of bathymetry and backscatter imagery data derived from multibeam, interferometry, and sidescan sonars.
Reading GMT grids: Fixed a very significant bug that caused GMT grids to be read into memory incorrectly by mb_read_gmt_grd() in src/mbaux/mb_readwritegrd.c. The problem was that the GMT default padding of grids by 2 grid cells around all edges was applied incorrectly, with a result that the topography (or other data) in the grid was shifted two grid cell widths north. The creation of grids by mbgrid or mbmosaic was correct; the problem came when the grids were read in by mbgrdviz, mbanglecorrect, mbprocess, and mbnavadjust.
