[Gdal-dev] Adding SDE Raster Support to GDAL

[David W. Lowther]

All,

Is this work intended to support read only or read / write?

Radesh,

I assume I spoke to you briefly about this at the MUM/OSGIS meeting?
There
is a fellow from ... somewhere in Alaska ... who has started work on
this.
He, you and I should coordinate on this to avoid undue rework.

Digging through my old email, I find I have an email from a Jay Cable at
"gi.alaska.edu" which appears to be the Geophystical Institute at the
University of Alaska in Fairbanks.  I think the fellow I talked to at
MUM/OSGIS
was either him, or perhaps a co-worker.

I'm cc:ing Jay to bring us together, though he might already be on the
list.

After soom discussion last week, I have come to the conclusion that SDE
has explicit tiling so we should initially tie directly into that.  So
that
means we just need to properly describe the the tile size and implement
IReadBlock().

Once the "full resolution" mode is working properly we can add the
ability
to read from overviews properly.  This mostly involves wrapping them in
raster band objects as well.  So (at least without the overview mode)
the
existing GDAL Driver Implementors guide should work pretty well.

Best regards,
