ogr2ogr is stripping non-FID fields

[pnorman]

This causes errors when it tries to render

No idea why I've never seen this before

$ ogrinfo --version
GDAL 1.11.2, released 2015/02/10

Do we still need to run it through ogr2ogr? I can't recall if we've broken Mapnik 2.2 support in some other way.

Which non-name fields do we need?

[pnorman]

Fixed topic, it's stripping non-FID

[matthijsmelissen]

Sorry, but what is FID?

[pnorman]

Sorry, but what is FID?

A shapefile field. Probably Feature ID.

[mboeringa]

A shapefile field. Probably Feature ID.

Correct, the equivalent of OBJECTID in ESRI File and Enterprise Geodatabases.
