[Qgis-user] Call for release name suggestions 2015
Dear QGIS community, As you might know, given our new release cycle with three releases a year, we are sooner or later going to run out of release names based on developer meeting locations. This is why I would like to remind you to suggest release names. If you have been hosting QGIS user meetings or if you have founded a user group, why not suggest the meeting/foundling location? Here's a short description of what is needed to make a suggestion: - CALL for QGIS RELEASE NAME SUGGESTIONS The following rules apply: - The suggestion should be the name of a place. - The suggestion must not be the name of a software product. (Please try to do some Google searches before submitting the suggestion.) - Each suggestion must come with a suitable map image for splash design. (Make sure that we have the rights to use the image. Since the splash is also printed in our user guide, a minimum resolution of 3000x2000 px is necessary.) - Locations of developer meetings have priority. Submission format: Send an email with a short description of your suggestion and a link to a ZIP file containing the map image(s) to anitagra...@gmx.at - Best wishes, Anita ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] Incredibly slow performance using QGIS v2.10
Hi, The Qgis dissolve is very slow. I tried to dissolve a SRTM water layer for province of Quebec and was unable to do it even with 64GB of memory and a SSD and 6 or 7 days of processing.nbsp;nbsp;nbsp; Use the Saga (or Grass) dissolve found in the processing toolbar.nbsp; It can do it in minutes!

Re: [Qgis-user] Incredibly slow performance using QGIS v2.10
Hi, I suggest to take the joined saved .shp file and use the Saga version of dissolve.nbsp; Using the Spatialite (click on layer and save shp as Spatialite) file could make things faster but the problem here is, to my knowledge, not the file format.nbsp; It's the QGIS dissolve.nbsp; See below. http://gis.stackexchange.com/questions/79850/merge-large-number-of-polygons-using-qgis Saga (processing plugin) will ask for a field for this dissolve.nbsp; Select the zip field or create a new Field with a dummy variable if you want to dissolve all.nbsp; (Use the field calculator if you which tonbsp; create this dummy variable).nbsp; If you see slivers, you can set a tolerance level (unit will be the unit of your CRS). Good luck! Nicolas Cadieux M.Sc.

Re: [Qgis-user] Incredibly slow performance using QGIS v2.10
I agree try Nicolas' suggestions first as they are easiest. My suggestion of Spatialite or Postgis was to also move the dissolve into a different tool as you would use the Dissolve function inside those DB formats with a query.
