Dear All,
Iam using QGIS 2.0 Dufour.I have created point location of
activities on a map.The assignment to assign some symbols to represent the
activities. The default symbols in the system can not represent my own

Hello,
I installed ELGIS and EPEL, but could not install qgis.
The instructions shown here:
http://www.qgis.org/en/site/forusers/alldownloads.html#rhel-centos-scientific-linux?
are:
sudo wget fedora.vitu.ch/EL/qgis.repo -P /etc/yum.repos.d/
sudo rpm --import http://fedora.vitu.ch/Fedora/RPM-GPG-Key-vitu
sudo yum update
sudo yum install qgis qgis-python qgis-grass qgis-mapserver
I had no problem with the first two steps.? When I ran the
yum update, I got:
http://fedora.vitu.ch/EL/6Workstation/x86_64/repodata/repomd.xml:
[Errno 14] PYCURL ERROR 22 - "The requested URL returned
error: 404"
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for
repository: qgis. Please verify its path and try again
Can anyone help?
Thank You,
Mark Ferris

you want to snap

My mistake. The shape file is the raster vegetation
map and the netcdf
file contains the hydrological metrics.
Sorry for the confusion.
Thank you for the help.

Hi,
In the 'layers' panel, set your focus to the raster layer of
interest.
Then click the 'i' button (identify features) and click on
the raster image.
The popup window gives you the pixel values, and the
'derived' dropdown
the position of that pixel in your 'CRS'.

Hi, I have a problem with not getting text labels to sort
under point symbols. Is this at all possible? I have
recreational symbols as accommodation, restaurants and so on
which need to take priority over village names etcetera.
Arranging the layers (these are different layers) does not
help and I cannot find a way to tell the labels to render
before the symbols.
Thanks!
