I'm not sure what you mean here. A shapefile is not "in seconds" or
"decimal degrees". The geometry part (*.shp) is a binary representation
of X-Y coordinates, as simple numbers. If the shapefile also has a
*.prj file, then that should contain its projection information.
If you have attribute columns (in the *.dbf part of the shapefile) with
X-Y coordinates, then you can format these columns any way you like
using, for example, Openoffice Calc. But this will *have no effect* on
the geographic location of the features in the shapefile.
So, the important question is: do the shapefiles overlay correctly? If
not, then you need to reproject one shapefile to the projection of the
others.
Hope that's clear...
Sorry I didn't make myself clearer. The shapefiles
are missing the prj files and the coordinates of the geometry are in
seconds for example 72.5 34.5 would be 261000.0 124200.0. I can write
a quick program to convert since it's a simple /3600 but it seemed like
I should be able to have qgis do it for me if I could figure out the
correct proj specification. I have used the transformation plugin in
the meantime to scale the data by 1/3600.
