Tekmap Consulting has added multi-thread support to the GTK+ MB-System interface. Processing time is greatly reduced by running select mb-system commands in separate threads. The mb-system commands include:
These programs require very little system memory, and do not take too much CPU time. By placing them in multiple managed threads, the processing time for a block of multibeam files is significantly reduced.
Introduction
The r.in.mb GRASS/Mb-Stystem program is designed to import mbio compatible multibeam data directly into the GRASS GIS.
The program is a modified version of r.in.xyz. Instead of reading an ASCII XYZ file, r.in.mb reads an MB-System compatible list file as shown below.
