Re: [Qgis-developer] spatial joins and select by location should not consider polygons than only touch
Hi, Well, if someone works on improving the intersection functions it would make sense to introduce a threshold value to allow to ignore area/area intersections with very small overlaps (e.g. very small sliver polygons overlapping). But I doubt that all of this would happen by itself without someone investing time or money into it. Certainly not for QGIS 2.4 where we are in feature freeze already. Andreas Am 04.06.2014 16:58, schrieb G. Allegri: Both options should exist. Perhaps a checkbox to exclude those that only touch? Admittedly, in my own version I have three checkboxes: - include layers that only touch - include layers that only overlaps - include layers the are completely contained and they are all checked by default (which is an intersects) This let me take full control on the intersection matrix. giovanni Thanks, Alex ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

[Qgis-developer] Is useasdefault column in public.layerstyles correctly handled when retrieving default style?
Hi all, in QGIS (trunk updated from git to some days ago, but also in QGIS 2.2 and 2.0) I have seen a strange behaviour opening a postgis layer in with some saved styles in table public.layer_styles. All styles have useasdefault set to false (these styles only makes sense within some projects, should not be used as default styles). When I open the layer without any project, one of the styles is applied, in particular the one with update_time more recent. The exact query that finds the default style seems to be SELECT styleQML FROM layer_styles WHERE f_table_catalog='mydb' AND f_table_schema='myschema' AND f_table_name='mytable' AND f_geometry_column='the_geom' ORDER BY CASE WHEN useAsDefault THEN 1 ELSE 2 END,update_time DESC LIMIT 1 In my opinion rows with useasdefault set to false should be completely filtered out by the query. If all styles have useasdefault set to false, current query retrieves the most recent style while I think that no rows should be retrieved in this case and a random color style be applied. Thus I propose to change the query in SELECT styleQML FROM layer_styles WHERE f_table_catalog='mydb' AND f_table_schema='myschema' AND f_table_name='mytable' AND f_geometry_column='the_geom' WHERE useAsDefault ORDER BY update_time DESC LIMIT 1 Would you like me to open a bug?

Well - if you do it now there is a risk of conflicts if you merge it after the lift of the feature freeze.

[Qgis-developer] Opinion on plugin named prepair (and possible likes)
Hi, there was some discussions during the spring of the plugin prepair. Problem was that it needs to have a compiled kernel, c++, user UI is in python. I've tested it now both in linux (openSuse 12.3 and QGIS 2.2 up2date) and windows (w7pro/64 and QGIS 2.3 nightly latest) environments. In linux the program has to be compiled by user, this might cause some problems if user is not used to compile programs, check libraries etc. For seasoned user that only takes some 5-10 minutes to get it done. In windows there is precompiled package but only as zip not with any installer which may cause problems (e.g. where to place it). Both installations worked with certain settings and included test case, results were similar, but further test settings caused big problems in windows installation which I'll report after a good night sleep. There will be real use for the plugin. But some development is needed also for UI. Conclusions Plugin is useful and thus very acceptable, but - it can be installed only by person who knows what to do, those people who do digitizing are not always programmers (very seldom) - to tell where the actual workhorse is situated is quite clumsy way to use it even the plugin remembers the site (but only in that same session), this should developed to some settings. Now You find it once and write it on paper not to need to find it again etc. otherwise you spend time and possibility to make error?. - these kind of plugins should be marked always as experimental and with this I mean all similar need-to-be-compiled plugins Cheers, Kari PS. I really liked the idea of this plugin and respect the developers. I also understand that maybe something I didn't understand why windows didn't work as expected. -- Kari Salovaara Hanko, Finland Volunteers do not necessarily have the time; they just have the heart. ~ Elizabeth Andrew ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
