In my country, we have a special epsg-code for transformation (#4649). In the definition (http://www.epsg-registry.org/report.htm?type=selection&entity=urn:ogc:def:coordinateOperation:EPSG::4649&reportDetail=short&style=urn:uuid:report-style:default-with-code&style_name=OGP%20Default%20With%20Code&title=), a
shTransCom.dll will be listed as a component. I have this.
Now my problem - there are several shapefiles I want to transform by using epsg:4649. One idea is to use QGIS- but how to integrate the dll-file? Normal epsg-code in my knowledge are ony a long list of parameters.
On the other side, my idea is to extract the coordinate - transform in another step - and reinject the new coordinates. One possible packet for perl could be http://search.cpan.org/~jasonk/Geo-ShapeFile-2.51/ShapeFile.pm.
Does anyone have another or a better idea - or could describe how to integrate epsg:4649 into QGIS?
