Even,
I agree with your response. Regardless of specific implementation I think
your efforts to provide high speed random access searches by ordinal
position for the database drivers will be a fantastic addition to the OGR
library. I am really excited to check it out when you get it ready for
tes

Even and Frank,
1. I would absolutely not change any existing functionality of how FID is
handled or you will screw up everyone's code that depends on that and will
cause a lot of people serious grief.
2. I cannot remember exactly but I think SetNextByIndex was intended to
solve this problem

Martin,
I take the liberty to CC the list, as it is an interesting issue and it's better
to go public if we want to make progress on that.
In a few words, this is about how we could speed up GetFeature() on the layers
returned when issuing a SQL request on OGR drivers that rely on databases : PG

Will your patch appear in trunk/gdal/alg at some point in time?

Jose,
Thanks for your pointer to your web site. Looks like you have some
very interesting and useful code there. I've been trying to do
something similar, though I use raster "zone" grids rather than vector
layers; I'd be happy to share that code, but it's too messy at this
point. I'll write a blo
Hi,
There is also a tool called Starspan than uses GDAL and GEOS to do
arbitrary zonal stats.
