[postgis-users] ESRI GDB format into PostGIS

[Michael Toews]

Hi, 

I had to check the current version. Manifold, like OGR, only supports ESRI Personal Geodatabase (*.mdb) format. Not ESRI File Geodatabase format. See: http://www.manifold.net/info/formats.shtml

Simon,

Are you suggesting that Manifold GIS has reverse engineered the file
geodatabase format?  Can you provide any pointers supporting that?
If those guys can reverse engineer it, then so could we given enough
desire.

I too am disappointed that ESRI declared they would provide open access
to file geodatabases, and then let the actually follow through drag on
for years after they came into initial use.  However, I do believe they
are contemplating a reasonably open API - possibly source included.  They
have also been considering support for an FDO and/or OGR provider.  I'm
a bit vague on the current plan but they are aware of these possibilities
and are interested in doing them.   So don't be so sure about what will
never happen.

Best regards,
