[GRASS-user] Memory problems with v.in.ogr
Dear list, I am trying to load a pretty big shapefile on GRASS (6Mb +, 211621 features) using v.in.ogr, but each attempt fails at the 'break boundaries'' stage (at 98%!): GRASS 7.0.svn (NZTM2000):~ > v.in.ogr dsn=~/Documents/DATA/LCDB2/ni_nzmg.shp out=ni_lcdb2 --o Projection of input dataset and current location appear to match Layer: ni_nzmg Counting polygons for 211621 features...

(Similar to D_FORMAT / > OUTPUT_DEGREE_FORMAT in GMT, I suppose). right, it automatically truncates off extra zeros. I usually use the map_info instruction which shows the full bounds. Unfortunately there's no way to switch off that feature without modifying the source code. if you wish to do that, edit ps/ps.map/do_grid.c and in the do_grid_numbers() function edit this line -from, +to: -sprintf(num_text, "%s", format_northing(g, rounded_grid)); +sprintf(num_text, "%s", format_northing(g, 1)); and then recompile. (untested) you may also try out ps.output from the Addons collection, it has more advanced border controls: http://grass.osgeo.org/screenshots/images/probabilidad_de_infeccion_crop.jpg (which at some point will be merged into ps.map too) Hamish ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
Fwd: [GRASS-user] i.gensig comment- Signature 1 not positive definite
I had this same error message sometime in the past few weeks, and I can't remember exactly what I did, but it was one of the following: 1) Data has to be transformed to 0-255 positive integers 2) You need to apply a mask to the null values 3) Possibly your training area is not large enough This is skirting your question a bit, as I can't tell you what the error message means. But hopefully you can find your way around the problem with one of the above steps! And, if you figure it out please let me know so I can write it down this time...

[GRASS-user] Grid label format in psmap
Hi, I have a UTM dataset that I am plotting with psmap. I would like to have grid squares at 1000 m intervals. I can do this easily with the following: grid 1000 color black numbers 1 font helvetica fontsize 12 end* *However, on the resulting plot, the gridline labels are truncated into kilometers e.g. 498, 7114, instead of 498000, 7114000. Is there a parameter that I can modify somewhere so that I can control output format and display the full number. (Similar to D_FORMAT / OUTPUT_DEGREE_FORMAT in GMT, I suppose).
