[Qgis-user] Qgis-user Digest, Vol 77, Issue 90

Thu Jul 26 10:18:18 PDT 2012

Well, several things.

First, why do you need to get rid of the space? 

Second, it appears that ArcMap will not let you return to nothing once
something was in the field.

The easiest way to fix this, if it is really necessary, is to select all of
the fields that are NOT " ".  Next, add a new field and calculate it to
equal the old field.  It will only do it for the selected records.  So, all
that are not " ".  This will result in the fields that were " ", being "".
Delete the original field and you are golden.

Again, though, it seems like a pointless exercise.  I do not know why the
space is a problem.

I heard a rumor a while back that someone was developing a plug-in to link
QGIS to Inkscape, anyone know if this is true? I'm a print
cartographer and work
primarily in Adobe Illustrator, a program which is made for vector graphic
design, with the Mapublisher plug-in, which allows you to bring in GIS data
and keep it's attribute and spatial properties (ie you're not limited to
importing SVGs). In my workflow I do use QGIS and GDAL/ogr2ogr to prep my
data before hand. You can then use Illustrator's vastly rich text and
graphic formatting tools to make really beautifully detailed or well
designed simple maps fairly easily. It would be great to see an opensource
equivalent plugin for QGIS to Inkscape.
