[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.

RE: [Qgis-user] How Do I Set Field Calculator Units For Area
Hi there, I *think* the area calculations are always in the unit for the layer's CRS. So you could either: - find out what this unit is, and convert the areas to square feet by multiplying by the correct factor, or - convert the layer to a CRS which uses square feet. N.B. there is a feature request to enable coordinate conversion in the field calculator (although I didn't mention that it would be useful also for area and length calculations).

Classification method is Unique value with the old symbology and Categorized with the new symbology. Neither of them show me the attribute value list. I made some more trials.

Re: [Qgis-user] Rasters alpha channel black instead of transparent
Hello Alister, Yes, the problem is exactly this. It happens to me on Windows with QGIS 1.7 standalone and 1.8 from osgeo4w. It also happens on Linux 1.7 (not tested in 1.8 master on Linux).

This is a very bad thing actually because axis order in EPSG:3067 is Easting-Northing but EPSG:3067 is using Northing easting. This difference will make you mad with WMS 1.3.0, WFS 1.1.0, GML 3 and so on. Compare http://epsg-registry.org/report.htm?type=selection&entity=urn:ogc:def:crs:EPSG::3047&reportDetail=short&style=urn:uuid:report-style:default-with-urn&style_name=OGP%20Default%20With%20Urn&title=EPSG:3047 with http://epsg-registry.org/report.htm?type=selection&entity=urn:ogc:def:crs:EPSG::3067&reportDetail=short&style=urn:uuid:report-style:default-with-urn&style_name=OGP%20Default%20With%20Urn&title=EPSG:3067 There is probably another issue which will give you 100-200 meter transformation errot because Proj4 tends to lack the +towgs84 parametert for the Finnish KKJ zones (EPSG:2391-EPSG:2394). All programs using Proj4 make this same error (GDAL when using the EPSG codes for giving the projection, Mapserver, PostGIS, Spatialite etc.) It may be that the very latest Proj4 comes with correct +towgs84 parameters but it does not help with old program versions. The only really reliable way for doing the conversion is to use ogr2ogr from command line. Read the instructions from http://latuviitta.org/documents/YKJ-TM35FIN_muunnos_ogr2ogr_cs2cs.txt (in Finnish). You can use other tools as well but compare always the result with something you know to be correct. And if some program works now, after program update the transformation can be wrong again. Do not ever trust that conversion between KKJ and other systems goes right. Best thing to do is to make conversion right once and after that stop using KKJ at all. -Jukka Rahkonen- ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
