Re: [Qgis-user] Domains darstellen
Hi If you are working with M-Shapefiles, the event layer plugin in the public repository (http://plugins.qgis.org/plugins/event_layer/) provides similar functionality as the event layer function in arcview. Don't know if it can be usefull for your purpose.

Re: [Qgis-user] Copy / paste features to spatialite generates
Hi Josef and thank you for your reply. I am actually using Qspatialite plugin to manage my spatialite layers. I checked the metadata of my database and my geometry column is of type MULTISTRING. I use Qspatialite to transform shapefiles in spatialite and the other way, but I'm not sure how to use it to copy only some feature from a shapefile to a spatialite table. I think I have to upload it to the spatialite archive and then use sql to copy data from one table to another. I'm afraid this is not so user-friendly, and my colleagues can hardly handle data in this way. Maybe actually it's better to continue using shapefiles as feature containers and wait until spatialite becomes a little bit more handily. - Julian Bogdani jbogd...@gmail.com http://bradypus.net On 17 Sep 2012, at 2:01 , Josef K wrote: Hi Julian I guess your problem is related to geometry types (http://www.gaia-gis.it/spatialite-2.4.0-4/spatialite-cookbook/html/new-geom.html).

Re: [Qgis-user] getting statistics from a raster layer
Thanks Nick and Carlos, Following the suggestions I got an error message: Cannot compute bounding box of cutline. when cutting the raster. I cannot understand where is the problem. It happened only with this kind of raster. I tried with nautical charts and georeferenced maps from Google Earth and I cut them without problems. Any ideas? Also I installed SAGA and GDAL. SAGA is great but it will take a time to me to verify all options. GDAL - statistic by zones gives part of the answer (count, sum and mean) in a very convenient way, creating columns at the attribute table. There's no need to cut the raster. Nevertheless I need max and min at least. If I could get max, min, std this way it would be the heaven. So, my point now is to cut the raster, or find another tool as statistic by zones with more parameters. All the best, Antônio 2012/9/15 Nick Hopton nhop...@gmail.com I think the first thing to do is clip the raster to your area of interest using the vector polygon. Raster - Extraction - Clipper. Select the polygon shapefile as the mask layer. To get the statistics load the clipped raster, right-click on it in the layers panel, select Properties and then click the Metadata tab. This will show the mean, min, max and SD, but not (unfortunately) the median.

[Qgis-user] Automatizing map making
Hi, I have been using QGIS for a few months now after almost a decade using Maptitude and TransCAD (from Caliper Corporation). Now that I already know how to get around pretty well with QGIS, I want to use it to production of series of maps (from a few dozens to hundreds at a time). My current problem is to make simple maps with graduated style and fixed classes for several different fields on the database. Looking at the PyQGIS documentation helped a bit, but I got several errors like NameError: name 'QtGui' is not defined and for many other names/libraries in the sample code I used, so I'm pretty sure that I have something missing that was not mentioned in the documentation or that I missed. Further, I'm interested in making maps with fields that are not in the database, so I need to make a join too (which is not mentioned anywhere in the documentation I saw). I would imagine that there is a way to open a project, change something (like the fields for the graduate rendenring), update the map composer and save the jpg, but I didn;t see anything like that... Did anybody face a situation like this? Any recomendations? Any sample code you could share?

[snip] As you can see in the same file other traces of older files are still present in the xml, for instance near lines126 and following: a list of vector layer with snapping turned on. This does not produce any error, but getting them removed when layer is removed is probably cleaner. As a you're not hallucinating comment (rather than a solution) I also have seen such things, although I'm not sure I have an example to hand. Is it just in projects saved by QGIS 1.8? I think from memory mine are with relative paths, and are projects originally started under an earlier QGIS version. Save As did not work for me either. -ramon. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] Automatizing map making
The best tool I know for scripted cartography is GMT (Generic Mapping Tools). ogr2ogr will execute database queries output GMT compatible datasets. For things like for species in list, draw map it is very powerful effective. But doesn't help with how QGIS can do this I'm afraid.

Now that I already know how to get around pretty well with QGIS, I want to use it to production of series of maps (from a few dozens to hundreds at a time).
