Hi,
For those not actively following github tickets & PR, I just
want to point to a new pending major functionality to improve
management of virtual mosaics with a very large number of
tiles/sources (> tens of thousands of tiles), by referencing
them as features of a vector layer (typically created by
gdaltindex), instead of a XML file as in traditional VRT,
augmented with additional metadata.
More details in https://github.com/OSGeo/gdal/pull/8983 (and in
initial ticket in https://github.com/OSGeo/gdal/issues/8861)
Am I right in thinking that all the tiles must have the same
bit-depth and colour interpretation and for paletted tiles
the same colour table ?
I am aware of a vendor whose products had different colour tables,
and even different bit-depths, for each tile - a sort of adaptive
compression.
