Standard messages sandbox First letter should be capitalized Use the present tense (cannot instead of could not; better: unable to; even better: avoid the issue altogether by rewording like "File not found.") Avoid contractions (cannot instead of can't) Good sentence construction ("Cannot find input map <%s>" instead of "It could not be find input map <%s>"; possibly better: "Input map <%s> not found.") Be consistent with periods. Either end all phrases with a period or none. Without periods the translators save also some time Complete sentences or all parts of a message with multiple sentences should end with periods. Short phrases should not. Punctuated events, such as errors, deserve a period. e.g. "Operation complete." Phrases which imply ongoing action look odd

The recipes can be tried in any order but it is recommended to go through the Getting started section first. Each recipe can be reproduced with publicly https://trac.osgeo.org/grass/wiki/MessageStandardization available demo dataset. The cookbook presumes that the user has QGIS with the GRASS GIS plugin installed (and GRASS GIS plugin enabled in QGIS) and that s/he knows QGIS basics. Note: as alternative, there is the Sextante-GRASS GIS support in QGIS available since 2012 which offers a simplified integration with respect to the toolbox explained here. GRASS Toolbox in QGIS All the recipes (except some in Getting started https://grasswiki.osgeo.org/wiki/QGIS_GRASS_Cookbook section) requires open existing mapset (you can learn that in the OpenMapset section how to open a mapset). If a recipe has input maps in header it is expected that the maps are displayed in QGIS (you can learn that in the DisplayMap section how to display a map). The requested input maps are described in form 'map@mapset' which is the standard GRASS notation. The information about effort (number of clicks and key strokes per each recipe) is only approximate. Demo datasets: North Carolina + Spearfish: get ZIP for Windows users, TAR for Linux/Mac users Getting started Display Map (18 clicks) Create new Mapset (13 clicks, 5 keystrokes) Open existing Mapset (12 clicks) Using GRASS Toolbox (11 clicks, 6 keystrokes) Displaying GRASS Maps Objective: Display GRASS maps in QGIS Dataset: Spearfish Effort: 18 clicks By: Radim Blazek In GRASS Toolbox click on Add GRASS raster layer tool In Select GRASS raster layer dialog which opens: (screenshot) click on Browse button and in the standard file dialog select the director where you extracted Spearfish demo dataset.

GRASS doesn't perform any locking on the files within a GRASS database, so the user may end up with one process reading a file while another process is qgis grass in the middle of writing it. The most problematic case is the WIND file, which contains the current region, although there are others. If a user wants to run multiple commands concurrently, steps need to be taken to ensure that this type of conflict doesn't happen. For the current region, the user can use the WIND_OVERRIDE environment variable to specify a named region which should be used instead of the WIND file. Or the user can qgis grass plugin use the GRASS_REGION environment variable to specify the region parameters (the syntax is the same as the WIND file, but with newlines replaced with semicolons). With this approach, the region can only be read, not modified. Problems can also arise if the user reads files from another mapset while another session is modifying those files. The WIND file isn't an issue here, nor are the files containing raster data (which are updated atomically), but the various support files may be. See below for ways around these limitations. Background This you should know about GRASS' behaviour concerning multiple jobs: You can run multiple processes in multiple locations (what's that?). Peaceful coexistence. You can run multiple processes in the same mapset, but only if the region is untouched. If you are unsure, it's recommended to launch each job in its own mapset within the location. You can run multiple processes in the same location, but in different mapsets. Peaceful coexistence. Approach Essentially there are at least two approaches of "poor man" parallelization without modifying GRASS source code: split map into spatial chunks (possibly with overlap to gain smooth results) time series: run each map elaboration on a different node. See the Parallelizing Scripts wiki page Working with tiles Huge map reprojection example: Q: I'd like to try splitting a large raster into small chunks and then projecting each on
