LS, We are using Quantum GIS for our wardens. I have a question of which I don't know where I can put it so I'm hoping one of you can get me into the right direction.
On our clients we have Windows XP sp2 as Operating System and on our fileservers we have Microsoft Server 2003 as Operating System. We store our data files (shape files and raster files (ecw)) on the central file server. For a shape file with a .shp file (size 3 MB) and a .dbf file (size 155 MB) it takes 7 minutes and 30 seconds to get the shape displayed on screen. Between the two locations there is a WAN of 10 Mbps. Other applications (MapWindow, ArcGIS, DIVA-GIS) only take 40 seconds to do the same. My presumption is that Quantum GIS first downloads the entire shape file onto the client before rendering. The other applications seem only to download the .shp file and to approach the .dbf file on the file server. I have observed that it is the .dbf file that is taking the time because when I deleted a number of fields in the specific .dbf file time dropped to about 3 minutes (and the size of the .dbf file dropped to 85 MB). The other applications still gave the same result of 40 seconds. Can someone of you please tell me how Quantum GIS handles shape files on a remote file server and if / when Quantum GIS will be able to get the same results in performance as the other applications mentioned above? I'm looking forward to receiving your answer.

I don't set any CRS. Setting to 4326 still crashes. I wanted to get some confirmation before opening a ticket. I now have contradictory results. Some work fine, 1.6 crashes, I'm the only one that has a crash in latest trunk. So I'll open a ticket.

Enviroment: Windows XP QGIS trunck R15470 The problem is the on the fly. It is need use the same CRS of the OSM (EPSG: 4326) to work with others layers.

Agree, there are problems with the georeferencer https://trac.osgeo.org/qgis/ticket/3596 with the "zoom to best scale" https://trac.osgeo.org/qgis/ticket/3609 and with GRASS rasters https://trac.osgeo.org/qgis/ticket/3582 https://trac.osgeo.org/qgis/ticket/3603 plus this that is really a stopper https://trac.osgeo.org/qgis/ticket/3602 cheers -- Giovanni -- ------------------------------ Message: 5 Date: Mon, 14 Mar 2011 13:29:16 +0100 From: Ziegler Stefan <[email protected]> Subject: [Qgis-developer] QgsPostgresProvider and UseEstimatedMetadata To: qgis-developer <[email protected]> Message-ID: <H00002ea08fdcfe4.1300105754.srsofaioi6145.ktso.ch@MHS> Content-Type: text/plain; charset="iso-8859-1" Hi I have some problems with the zoom to full extent functionality with posgresql layers. It seems that it is always selecting the estimated extend and never the real extent from postgresql even with an unchecked "Use estimated table metadata" checkbox. regards Stefan Mit freundlichem Gruss Stefan Ziegler Leiter amtliche Vermessung Kanton Solothurn Bau- und Justizdepartement Amt für Geoinformation Rötistrasse 4 4501 Solothurn Telefon 032 627 75 96 Telefax 032 627 75 98 [email protected] http://www.so.ch -------------- next part -------------- An HTML attachment was scrubbed...

At the moment, the diagram overlay plugin has more options (bar diagrams and the proportional svg symbols). Therefore I'm planning to remove overlay code and plugin after 1.7 because of backward compatibility. > - does it make sense to you to remove the "overlays" tab in the > options dialog?

Conceptually, it is the other way round (renderer is a part of the layer settings). But agreed, there is no need to keep both variables in the vector layer. Keeping only the settings variable should work too. Regards, Marco Am Montag, 14.
