2013 - technology preview

[sandro furieri]

Hi list,

A nice new, one probably warmly welcome for many of us.
Even Rouault (the maintainer of the GDAL library) during the latest
weeks has implemented VirtualOGR, a loadable extension enabling
SQLite/SpatiaLite to directly connect many external datasources,
this including the most popular Spatial DBMSes (PostGIS, Oracle ..).

Today I'd finally enough free time to perform some preliminary testing;
anyone interested into this topic can read my preliminary report:
https://www.gaia-gis.it/fossil/libspatialite/wiki?name=VirtualOGR

Please note: VirtualOGR isn't yet officially available: it will be
probably released on December.
Anyway "rogue explorers" could easily perform some preliminary testing
just today; building by yourself few libraries from devel/trunk code
is the only pre-requisite (a trivial task for any Linux user).

happy testing,
Sandro

Hi, Alessandro and Even
thx for this great improvment to the spatialite and ogr usage.

Also the report from Alessandro, as usually, is a great start point.

I'm interesting to try it with our datasets.
I'm interesting to try to use it with our topological GML.
It need some starting parameters like:

GML_FACE_HOLE_NEGATIVE
and
GML_SKIP_RESOLVE_ELEMS HUGE

Is possible to pass this parameter to virtual-ogr ?

Thx,

Andrea.

yes, you can always define them as environment variables before starting
spatialite tools.
