[Qgis-user] Re: Qgis-user Digest, Vol 67, Issue 1
WRT Message 2 and the Profile from line tool I also had a problem using this plugin. I am running Mac OSx ver 10.5.8. I have installed QGIS and Python and the other suggested package installers. I found the shapely tool and downloaded it tried to install but had no joy. Used the Python 3.2 tool to try do that. Any ideas or help would be greatly appreciated.

You need to put the shapely folder (from inside PURELIB) in e.g. C:\OSGeo4W\apps\Python25\Lib\site-packages\, and the geos.dll and libgeos-3-2-2.dll in I think C:\OSGeo4W\bin, although instead of installing those I seem to have got it working by editing C:\OSGeo4W\apps\Python25\Lib\site-packages\shapely\geos.py to use the lib from OSGeo4W instead (C:\OSGeo4W\bin\geos_c.dll). For the record, there is also an open ticket (with a suggested script) for registering the OSGeo4W Python with Windows, so that python package installers can find it: http://trac.osgeo.org/osgeo4w/ticket/114 Regarding the profile tool plugin, Micha, it definitely runs on Windows. But on one of my machines I also got that error message about having no Qwt5. If I remember correctly, the problem was something like this: it requires the latest Qwt5 (or PyQwt5) in the OSGeo4W repository, but this machine only had an older version installed, and the OSGeo4W installer was not showing the latest version for some reason. I believe to fix it I uninstalled PyQwt5 and Qwt5, then reinstalled them.

Hi Giovanni, Either you are mistaken, or there is a bug.

Oh, I should also mention that if I copy a feature to another layer which uses a different CRS but the same units, then the field calculator returns a _slightly_ different area (e.g. NZGD2000 vs NZGD49). -Original Message- From: Alister Hood Sent: Friday, 2 September 2011 10:28 a.m. To: 'giovanni.man...@gmail.com' Cc: qgis-user@lists.osgeo.org Subject: RE: [Qgis-user] How Do I Set Field Calculator Units For Area Hi Giovanni, Either you are mistaken, or there is a bug.

Re: [Qgis-user] Toporama in QGIS in UTM
Thanks for the success report. I'll reinstall the latest QGIS and see if it helps. I notice that regardless of what I do with the project CRS the coordinate box at the bottom of the window still shows lat-long type coordinates (you know -115, 51) not UTM type coordinates (-10188693, 15984693 in your example.) When I try to zoom-to-layer it doesn't move, so maybe zoom-to-layer is broken with WMS? I tried zooming out far enough to show it but I don't think I zoomed out to 10 to 15 million.

[Qgis-user] Problem on Starting QGIS after compiling from sourcecode
Hey guys, here's my problem for days: I compiled QGIS 1.7 from source code on my Win7 32bit system using VS2010, according to official instruction INSTALL.pdf. There's little problem on compiling: 1. downloaded and installed depended components including cmake, flex, bison, osgeo4w (with needed plugins); 2. recompiled qt SDK for VS2010; 3. built a batch command file using the codes from INSTALL.pdf; 4. configured the build folder using cmake-gui.exe; 5. opened the generated qgis.1.7.0.sln using VS2010; 6. run the ALL_BUILD, INSTALL, PACKAGE, uninstall targets in VS2010. Everything runs well without one error. Finally, the INSTALL target built a program foler C:\Program Files\qgis1.7.0, and the PACKAGE target built an installation exe package. However, I cannot start the generated qgis.exe program. Every time I click the icon, the OS tells me that the program is crashing. The INSTALL.pdf said, I should includes all needed Dlls to run the program. But how do I know which dll is needed? I compared the folder structure to the standalone version's folder structure, finding little in common. Anyone know some details?
