Re: [Qgis-user] Ideas for QGIS plugin?
yes - a nice gdal frontend for cropping/merging/resampling rasters would be cool. I also thought it may be possible to use the Google maps data from within QGIS. One could probably use a hidden Webkit to make Google think it is a regular webbrowser that is requesting the tiles - and then merge and potentially reproject the GoogleMap tiles to use it as a regular background layer in QGIS.

Re: [Qgis-user] New GIS User, What to use (QGIS, GVSIQ or UDIG)?
I'd have to second Carson's comments. I come from 10 years experience using ESRI products. When I starting getting into open source GIS just over a year ago, QGIS was much easier for me than gvSIG or UDig. Now, I prefer it over ArcMap when dealing with shapefiles. - John ** John Callahan Geospatial Application Developer Delaware Geological Survey, University of Delaware 227 Academy St, Newark DE 19716-7501 Tel: (302) 831-3584 Email: john.calla...@udel.edu http://www.dgs.udel.edu ** Carson Farmer wrote: Hi boesiii, A client of mine needs softwate to edit shapefiles and was wondering what's the easiest and best to use (QGIS, GVSIG, or UDIG)?

I've implemented something very similar in the recent Table Manager: 1. save the modified layer to the temp directory 2. try to remove an old dbf~ backup if any (see the next point) 3. backup the original dbf file as dbf~ 4. replace the original dbf with that one from the temp. You can see it in the tableManager_gui.py file, method TableManager.doSave (today they are lines 441-508) ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

[Qgis-user] QgsCoordinateReferenceSystem in
Hello list!
I am happy OSGeo4W user with QGIS 1.0.0-5.
I got strange things using QgsCoordinateReferenceSystem in a custom
python script.
For example, from the following script:
from qgis.core import *
QgsApplication.setPrefixPath("C:\OSGeo4W\apps",True)
QgsApplication.initQgis()
cs = QgsCoordinateReferenceSystem(2180)
print "EPSG ID:", cs.epsg()
print "Is it valid CRS? ", cs.isValid()
QgsApplication.exitQgis()
I get:
EPSG ID: 10
Is it valid CRS? False
On my Ubuntu machine I got similar things...
When I check the script in python console of QGIS:
>>> newcs = QgsCoordinateReferenceSystem(2174)
>>> ncs.isValid()
True
>>> ncs.epsg()
2174
Do you have the same?
Thank you for any info.
Radek
