Re: [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

Re: [postgis-users] importing curved polygons

[Neumann, Andreas]

Hi Rich, 

What GDAL/OGR version do you have? Which driver do you use? There are
two. 

According to 

http://www.gdal.org/drv_openfilegdb.html
and
http://www.gdal.org/drv_filegdb.html (requires ESRI FileGDB API SDK)
both versions require version 2.2 or higher. 

It is quite likely that you use an older version. 

Try "ogrinfo --version" to get the version.

[postgis-users] importing curved polygons

[Richard Greenwood]

I have received an ESRI file geodatabase with polygons containing curves
that I would like to import into postgis. Using ogr2ogr the curved portion
of the polygon is comprised of the chord of the curve (example below).

Does anyone have any suggestions for importing an ESRI file geodatabase
containing curved polygons?

Thanks,
Rich
