In QGIS I open up the Custom CRS definition dialog Copy and paste a proj4 parameter line starting with +proj= into the Paremeters box Copy and paste the Name into the name box. Hit the little folder icon. Nothing happens. The number below the parameter line doesn't increment. Hit OK and the custom CRS isn't added to the database. Could my database be unavailable somehow? If I take a known, valid proj4 parameter line that QGIS has in it's database, it it won't add it either (I miswrote this below) I played around some more, and the test dialog WILL accept the custom parameter lines, and does say they are valid, I just can't get my database to recognize them. I remember the database dialog box when I first installed QGIS, I think I just took the defaults, in the DB manager it shows a SpatialLite entry, but there's a flashing alert in the bottom of the window that says "postgis No module named psycopg2" If I highlight 'SpatialLite" and click the SQL window icon, I get an error that says 'no database selected or you are not connected to it'. I'm not sure I have the necessary SQL programs installed. in Synaptic I have some sql packages, client libraries, shared libraries, python extensions. Do I need a specific core SQL package to get the database in QGIS to be accessible? In synaptic I tried to install python-psycopg2 and I got a warning that it could not be authenticated and malicious control etc etc etc, should I install it anyway? thanks, Janet > > On 10/27/2012 02:49 PM, j...@caltech.edu wrote: >> I'm trying to add one of the Albers equal area conic USA/North american >> projections as a user defined/custom CRS. >> >> QGIS 1.8.0 on Linux-Ubuntu. >> >> I went through every version on spatialreference.org/ but after entering >> the parameters (ie, +proj=aea +lat_1=29.5 +lat_2=45.5 +lat_0=37.5 >> +lon_0=-96 +x_0=0 +y_0=0 +ellps=GRS80 +datum=NAD83 +units=m +no_defs ), >> it >> still shows * of 0, and hitting the save button does nothing.
