Hi Emile, just for making maps you for sure do not need GRASS, GRASS is the Geographic Raster Analysis Support System - a GIS tool for real working with GIS data, but definetely not for creating nice maps... ;-) Therefore I think the print-composer of QGIS is very helpful, there was also a talk at FOSS4G recently, dealing with making maps with QGIS and Inkscape: http://2011.foss4g.org/sessions/quantum-gis-inkscape-cartographic-tools-attractive-maps I think very soon you might get the presentations lsides and also a video of the presentation itself.

Re: [Qgis-user] Using GRIB2 in QGIS
Ezra, QGIS uses GDAL to read GRIB files. GDAL's GRIB driver will not read the files on the site you listed as the g2clib GDAL uses is too old (v1.0.4) and does not support the GRIB GDT 3.204 Curvilinear Orthogonal Grid (supported in g2clib v 1.0.5).

Take a class or workshop at a local school, or read a few intro books.(http://shop.oreilly.com/product/9781934356067.do) You could also start with the QGIS Manual, or the QGIS Gentle Introduction pdf (both on qgis.org).

[Qgis-user] Can't get printed or plotted output
Hi people! Qgis newbie here, though I'm an experienced GIS user (ArcGIS), but not a guru, just a geologist. I created a map in Qgis and also three Print Composer instances. I set up one as a plotter file (Print Composer #1, 42 X 60) and another as a PDF (Print Composer #3, print as raster checked) after failing to get a completely plotted map document. The plotter output has a large area of empty paper in the middle as well as two narrow bands of empty space, all surrounded by the incomplete map. When I try the PDF workaround to simply get usable output that I can send to the plotter, I get an incomplete PDF document and a message Exception - bad allocation). Anyone have any suggestions? Not sure if this is a plotter problem, a Qgis garbage-in problem or ??? 1. Is there an organized Qgis printer/plotter troubleshooting forum that I can look at for some tips? 2. Is there an organized procedure that I must follow to ensure getting good output that I'm missing?___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
