Re: [Qgis-user] How to specify a local coordinate system

[Goyo]

2012/4/25 MacQueen, Don macque...@llnl.gov:
 I'm using QGIS to display drawings that come from CAD files (dxf). They
 are in a local cartesian coordinate system with a local origin, not
 related to any coordinate system known to PROJ4.

 How should I specify the coordinate system when I read the dxf file into
 QGIS (using Add Vector Layer)?

If you know how to describe your CRS using PROJ4 parameters, create a
custom CRS (Configuration  Custom CRS) and then assign it to your
layers.

[Qgis-user] How to specify a local coordinate system

[MacQueen, Don]

I'm using QGIS to display drawings that come from CAD files (dxf). They
are in a local cartesian coordinate system with a local origin, not
related to any coordinate system known to PROJ4.

How should I specify the coordinate system when I read the dxf file into
QGIS (using Add Vector Layer)?

I suppose I'm looking for something analogous to what GRASS happens in
GRASS, in the Define new GRASS Location wizard, with the Create an
arbitrary non-earth coordinate system (XY) option.

Thanks
-Don
