Re: [OSGeo-Discuss] Display of Multibeam data in open source gis [SEC=UNCLASSIFIED]
In addition to Grass, there are several image processing apps that may be of assistance: ossim: http://www.osgeo.org/ossim mbsystem: http://www.mbari.org/data/mbsystem/ rat: http://radartools.berlios.de/ Bruce On 18/07/10 7:15 AM, Markus Neteler nete...@osgeo.org wrote: On Sat, Jul 17, 2010 at 2:30 AM, cruise...@comcast.net wrote: am in a quandry, have dense/large multibeam files i wish to display i a GIS for various purposes, essentially XYZ files, in DD WGS84 coordinates, ASCII tab-delimited or Mapinfo mid-mif formats, up to 10-million points plus in a datset. 1. have tried GVsig and quantumGIS, but neither seems to like the ascii tab-delimited format. 2.

GDAL/OGR supports tabs in CSV files from 1.7.0 You should be able to convert other formats including Mapinfo to other formats using ogr2ogr.
