David,
I do not believe there is any way to make PROJ.4 use angular units other
than decimal degrees for geographic coordinate systems (+proj=latlong).
I thought that ogr used proj4 to do the coordinate transform? Does that mean
that ogr2ogr is converting using it's own transforms? It is converting the
shape correctly.
David,
While in theory OGR can use other coordinate system transformation
libraries, in practice this is not used. I don't know how ogr2ogr
could be handling something in arcseconds properly.
Best regards,
