Hi all, If the long term aspiration of having support for temporal data is to support NetCDF, HDF, GRIB, etc similar to: http://blogs.esri.com/esri/apl/2015/03/11/dimension-explorer/ then probably we need to have more to it.
Martin has done a major update of the crayfish plugin which now supports xdmf (a variation of HDF5) and soon we are looking to add animation feature and more file support: https://github.com/lutraconsulting/qgis-crayfish-plugin Cheers, Saber -----Original Message----- From: qgis-developer-boun...@lists.osgeo.org [mailto:qgis-developer-boun...@lists.osgeo.org] On Behalf Of Matthias Kuhn Sent: 30 March 2015 10:31 To: Nyall Dawson Cc: qgis-developer; grass-...@lists.osgeo.org Subject: Re: [Qgis-developer] Temporal data (was QGIS GRASS Plugin Upgrade Crowdfunding) Hi I think the very first step in this should be to add proper date (time) support. I don't know the state and requirements for raster layers, but for vector layers I think right now time is converted with the edit types just for visualization but internally it is passed around as string. It would be nice to handle them as QDate(Time) internally. For time-aware databases (postgres...) this should be straightforward. For others (like shapefile?) we probably need to manage the datatype on the project level but conversion should IMHO happen low-level directly in the provider code so things like timezone handling and whatever else needs to be done can happen exactly once when the data is read from the datasource or saved to the datasource. Filtering (from date ... to date ) should best be done on the QgsFeatureRequest level (setFilterExpression should already be ready I guess) Best, Matthias _______________________________________________ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer -- This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
