[postgis-users] importing curved polygons

[Richard Greenwood]

Thank you Andreas. Summary: Using ogr2ogr 2.2 (which hasn't been released
yet) curves are read from an ESRI file gdb and written to postgis as
curves. When building ogr without any explicit configure option for fgdb
the OpenFileGDB driver is used. To use the ESRI driver the --with-fgdb
option has to be used but I personally didn't get that working. Using the
OpenFileGDB driver is probably preferable unless you need to write to a
file gdb. I was told on the gdal-dev list that the Windows dev version of
gdal available at gisinternals probably supports curves but I have not
tried it.

As always, thanks for the help.

Rich
