[Qgis-user] PostGIS Manager plugin issue
Last night I installed/ran the PostGIS Manager plugin with no issues on my Ubuntu Intrepid laptop. Today (at work) I'm having an issue running the plugin on my Ubuntu(guest), XP(host) - VirtualBox install. I'll mention again that this worked right away on my laptop (after installing psycopg2) not sure what's going on now..However currently, when I click the plugin button, 1st I get the error msg: #Couldn't connect to database: #FATAL: Ident authentication failed for user "joe" So I CREATE USER joe in psql. Attempt to run the plugin again: #Couldn't connect to database: #FATAL: database "joe" does not exist I whip up a databased named joe and with OWNER postgres or joe I get the error below |### An error has occurred while executing Python code: Traceback (most recent call last): File "/home/joe/.qgis//python/plugins/postgis_manager/ManagerWindow.py", line 148, in dbConnect self.dbInfo() File "/home/joe/.qgis//python/plugins/postgis_manager/ManagerWindow.py", line 177, in dbInfo info = self.db.get_info() File "/home/joe/.qgis//python/plugins/postgis_manager/postgis_utils.py", line 113, in get_info self._exec_sql(c, "SELECT version()") File "/home/joe/.qgis//python/plugins/postgis_manager/postgis_utils.py", line 504, in _exec_sql raise DbError(e.message, e.cursor.query) DbError: MESSAGE: current transaction is aborted, commands ignored until end of transaction block QUERY: SELECT version() Python version: 2.5.2 (r252:60911, Oct 5 2008, 19:42:18) [GCC 4.3.2] Python path:['/usr/share/qgis/python', '/home/joe/.qgis//python/plugins', '/usr/share/qgis/python/plugins', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2', '/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload', '/usr/local/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages/Numeric', '/usr/lib/python2.5/site-packages/PIL', '/usr/lib/python2.5/site-packages/gst-0.10', '/var/lib/python-support/python2.5', '/usr/lib/python2.5/site-packages/gtk-2.0', '/var/lib/python-support/python2.5/gtk-2.0', '~/.qgis/python', '/home/joe/.qgis/python/plugins/fTools/tools'] ### Also, when I 'OK' the error msg and click on the public schema in the PostGIS Manager window - I get another err msg. I hope this is not just some User/Login issue with Ubuntu..but I would appreciate some insight*joe | ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

[Qgis-user] polygon formation problems!
Hello! Qgis users, I am a new user of qgis and wish to switch to open source but there are some usage difficulties that I need to be resolved. The polygons are created either by capture or splitting. There is no provision for creating an adjacent polygon with the help of a line. Secondly, whenever there are two polygons having common segment then there is overlaying of lines, which means that once the vertices are touched there is no more single common segment and it shows into two different segments. It has several demerits in terms of accuracy. I hope once these are properly addressed, I can go further into using this. Thanks!

There's a work in progress with Python and OSM, maybe it could be of interest for your development: http://code.google.com/p/osmlab/ giovanni 2009/1/31 Florian Hillen : > Dear mailing list, > > first of all I want to thank everybody for the input an the suggestions. > Some plugins are a bit to extensive for my bachelor thesis (I can maximal > write about 40 pages), so I pick up the suggestion with the OpenStreetMap > plugin and modify it a little. > Sometimes I'm in the situation, that I want to show somebody a track or > something, but didn't have the appropriate background data.

Hi,
I haven't tried qgis from osgeo4w yet, but it's possible that the CRS
is not found because of different paths to the qgis.db file (which
contains database of CRS). By default it should be located (on
windows) in "resources" subdirectory from the specified prefix path.
In case it's different, you could use
QgsApplication.setPkgDataPath(path) to change it.

Re: [Qgis-user] Ideas for QGIS plugin?
Dear mailing list, first of all I want to thank everybody for the input an the suggestions. Some plugins are a bit to extensive for my bachelor thesis (I can maximal write about 40 pages), so I pick up the suggestion with the OpenStreetMap plugin and modify it a little. Sometimes I'm in the situation, that I want to show somebody a track or something, but didn't have the appropriate background data. There are some ways to receive a shp from OSM-Data, but I think it's a lot more comfortable and maybe faster if it's implemented in QGIS as a plugin. So my plan is to build a plugin, that transforms OSM-Data to shp (either with an existing .osm file or with a given extend) and add a new layer (or many layers) to QGIS. If anybody knows that this plugin is already developed, please contact me! Thanks to everybody again and hopefully some of you will use my plugin in the future (even though I know that the plugin is more for private use than for commercial).

[Qgis-user] Re: Feature inquiry: Multiple display windows?
I share the interest on having linked displays, Sjur mentions several geographic displays (which could be even at different scales), but this could also be linking an scatter plot and the geographic display, for example. Could these ideas be included for the 2.0 roadmap? Agus Hello, Qgis community: I am not yet a QGIS user, but I'd like to know if QGIS supports several map display windows, possibly cooperating. One of the things I do most in my current GIS (which I am only partly satisfied with) is to compare two rasters. It would be nice to plot them in separate windows, and when pan/zooming around in one, the other would update its extent and show the same area. I also frequently have lots of raster windows up simultaneously, from the QGIS screenshots this does not appear common usage. To take it even further, the two maps could actually be time series, for instance repeated satellite images and simulated snow cover from a distributed hydrology model. Then also next/previous-buttons could be added to the display windows, again affecting both windows simultaneously. If I was to program such functionality (in C++, I don't speak Python), would it be standard plugin procedure using QGIS API,or would the display/GUI part of it require deep revisions of existing QGIS code? Regards :-) Sjur Kolberg Dear Sjur, for now you can try OpenEV (part of the FWTools [1]) out. It's fast and reads (almost) all kinds of rasters.
