[Qgis-user] Automatizing map making

[pcreso at pcreso.com]

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.

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? Thanks for the help, PedroUC Irvine 

   PS - Sorry for posting in two lists, but I really have no idea where to send this e-mail.
