TileIndexes and paths - a proposal

[Frank Warmerdam]

Brent,

If we can agree on how the tile index names, I am happy to implement it.
I haven't thought through your proposal carefully yet, but hopefully I
will get a chance to.

I presume you mean, what if the tileindex dosn't have a meaningful path?
Good question.

The other side of this is to keep in mind that the names in the tileindex
aren't necessarily filenames.  In the case of GDAL formats, they could
be a gltp: url for OGDI data, or a DODS url for DODS servers.

At this time that is not permitted.  All tiles in a tile index have to
be in the same coordinate system as the tileindex.

Best regards,
