Hi,
Any thoughts about alternatives to implement the feature request from
https://trac.osgeo.org/gdal/ticket/5762?
What I dream of is to be able to utilize all the nice on-the-fly tweaks that
can be done with VRT at similar speed that Mapserver is reaching with tileindex.
That would be a nice enhancement. As usual I guess we need a champion
and/or some funding to make this happen.
I came across a similar use case not long ago and realized that to get
top performance at all zoom levels we'd also need the ability to
associate overviews with the VRT. I didn't check if creating external
overviews with gdaladdo would work for a VRT already. Maybe it does?
