[QGIS-Developer] QGIS enhancement: export to GeoPDF

[Andreas Neumann]

Dear QGIS developers, 

One of our sponsors is asking if there are any ways/plans/upcoming
improvements regarding export to GeoPDFs. 

Specifically of interest are: 

 	* export of georeferenced data (query coordinates)
 	* proper export of the exact same styling from QGIS (the existing OGR
feature styling would be too limited)
 	* ability to toggle layers
 	* ability to query attributes from vector layers
 	* Offer an export similar to the export of DXF (exporting multiple
selected layers or the whole map at once).

Now I know that GDAL/OGR supports generation of PDF, but the styling
options are limited - see also http://www.gdal.org/frmt_pdf.html 

On the other hand, QGIS supports a lot of styling options which wouldn't
be exported correctly when writing to GeoPDF through gdal. 

So here are my questions: 

 	* Is there a dev out there who would be interested in working on it
and who could make a proposal how to properly support GeoPDF for export
from QGIS?
 	* Do you know of any similar QGIS users/clients who would be
interested in co-financing?
 	* Do you have any ideas how to technically solve the issue of
retaining style while also allow the querying of vector features?
Perhaps export as raster to retain style with invisible (transparent)
vector overlays?

Thanks for the discussion! 

Andreas
