The Shapefile driver supports spatial index from .qix file
(http://gdal.org/drv_shapefile.html), so assumably the spatial filter
set by SetSpatialFilter takes advantage of it.

Or maybe the question need to be if I set geometry as spatial filter using
the "SetSpatialFilter" function and then I use the function "GetNextFeature"
on a layer with spatial index, for instance shp file with qix. It will
consider the spatial index when fetch the next available feature from this
Hi,
If I use the function SetSpatialFilter on a layer of a shp file with spatial
index(.qix), will the function use the index to decide which features are
suitable?
Thanks,

it allows to draw a map that makes sense when using longitude as the

Hi,
Im totally new to GDAL, sorry if this is a obvious thing for you.
Trying to filter features in the area with following code snippet.
However
poLayer-GetNextFeature()
always returns null on my windows 8.

Is it still true that the geometry used for SetSpatialFilter must have
the same CRS as the layer?
