Dear all, just for your information: I have implemented a simple QGIS Plugin to browse and visualize GRASS GIS raster, vector and time series data in a fast way. It is not designed to run any GRASS GIS processing modules or to create, remove or modify GRASS GIS map layers.
The Plugin is implemented in Python and makes use of PyGRASS and the GRASS GIS Temporal Framework. The use of the PyGRASS RPC interface should avoid any G_fatal_error crashes. However, it introduces instead stalled pipes, hanging processes and forever waiting RPC calls. It allows IMHO fast visualization of raster map layers directly from a GRASS GIS database, without conversion or export. Vector maps are converted into QGIS memory layers, to allow all the great and fancy QGIS vector layer visualization features. A specific feature is the analysis of space time raster datasets (STRDS), which are visualized as a specific layer in QGIS. The corresponding raster map layers can be switched directly in the STRDS layer settings. In addition some basic statistical analysis can be performed on the selected temporal raster map layer and the whole time series. SQL WHERE statements can be used to select specific raster layer subsets in the STRDS layer settings. The Plugin is available here: https://bitbucket.org/huhabla/grass-data-explorer/wiki/Home I will not put it into the official QGIS Plugin repository, since it is too experimental and will be modified a lot. Be aware that this plugin only works with a very recent GRASS GIS 7.1 svn version. To run the plugin, QGIS must be started from within an active GRASS GIS session. Switching mapsets or locations is not supported. The plugin is highly experimental and has a lot of bugs. Hence, after closing QGIS, run "killall -9 qgis" to kill all the RPC processes, that are spawned to enable parallel data access. Use it on your own risk!! However, for me it is already very useful. :) Best regards Soeren _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
