Hi! I wanted to write that directly to pcav but as I see that this topic is right at the right time and position .. What about creating something like: http://www.esri.com/library/brochures/pdfs/arcgis93-functionality-matrix.pdf during the pisa hackfest? So that every new functionality can be seen in one sheet? (And probably we can take this sheet to compare ourself with arcGIS ;) ) I guess devided into core and plugin section that could be real helpful for people using qgis and searching for designate tools.

It has to be decided whether it will be in the appendix of the users manual or a sheet on its own.. (and in which way it will be produced) stay tuned ;) Hi, in any case consider that comparing qgis with the arc* functionality matrix will need at least two columns, in order to specify if the task can be accomplished by qgis alone and/or trough the grass plugin. It would be also interesting to specify if in qgis a particular task can be done by qgis core or trough a 3rd party plugin.

If the project is in wgs84 and the vector is not I get a crash (qgis 1.4, under linux) I'm using trunk on linux here. And yes, it is working. And trying both plugins on the same (multipolygon) project, I see some differences and issues ... - DPSimplify actually simplifies your data on the fly, and gives you the option to either save it to a new shapefile or not (nice !) - DPSimplify also reports the number of vertices reduced, which gives you the option to lower or higher your tolerance (nice) - DPSimplify seems to work only with line and polygons data (not multi* )? (at first there was no layer in the dropdown, untill I added a (non multi)polygon layer) - DPSimplify the about-box raises an python exception here Don't know when you add layers with a different projection to a map (like you do: the plugin has to do the 'on the fly projection' itself I think... this is a though case anyway)... And to make myself clear: I do not want to discourage Alexander to develop the plugin!! Because if I'm correct, the current vector-menu stuff is actually cpp ported from the former python plugin as well. I think the python plugins are a nice example and way for prototyping stuff to either (but not nessecarily) being ported to trunk, and hopefully raise interest for people to add functionality to qgis.

Re: [Qgis-user] Re: [Qgis-developer] announcing DPSimplify
Hello list, I'm a bit late coming into this discussion, by I thought I might be a good place to make a few comments: New plugins that add new functionality are always very welcome, however I would also like to encourage plugin developers to have a look at (particularly core plugins) existing plugins, and if they find something they would like to improve/replace, to do so! I don't have a lot of time to update fTools, but improvements are always welcome, and if they are added/applied to fTools directly, then the whole QGIS community benefits from the improvements/changes without having to install another plugin (and without duplication in the eyes of the user). And to make myself clear: I do not want to discourage Alexander to develop the plugin!! Because if I'm correct, the current vector-menu stuff is actually cpp ported from the former python plugin as well. Just to clarify, most of the fTools functions have still not been ported to cpp, and in fact anything running from fTools at the moment is still using the original Python implementation. So again, I would encourage developers of fTools functionality to try to include them with fTools so that they can be installed by users by default. Patches are always welcome, and credit will always be given where credit is due! Regards, Carson -- Carson J. Q.

Re: [Qgis-user] Re: [Qgis-developer] announcing DPSimplify
We'll be happy to move the plugin to fTools when we're done with it which will greatly improve its functionality. In general, we see most of our development in Vector area (Statist, JoinLines, DPSimplify to name the few) as potentially included in fTools (Vector) or enhancing present tools. Great!
