[fdo-internals] Raster Catalogs (aka Tileindexes)

[Greg Boone]

There are a couple of options for generating the bounds information in
the configuration file:

1) The FDO team can provide a small application or tool to create the
configuration file based on a set of input directories. Studio or
Studio developers could then use this tool to create the XML
configuration file.
2) Studio could use the FDO DescribeSchemaMapping command to generate
the schema mappings for a default raster connection made to a single
directory of images. However, as stated, this mechanism is limited in
that it only generates mappings for a single directory.

Jason,

I was assuming that the Studio developers would be doing something for
generating this config file in studio.  Actually, I have no idea how
people
normally create these config files.

Having said earlier that creating the config file should be easy, I must
confess that on sober second thought I'm not exactly sure how I'm going
to
approach it.  The GDAL PHP bindings and I'm not sure we want Web Studio
having a dependency on GDAL PHP bindings anyways.

In theory I suppose Web Studio can use FDO itself to get the bounds for
individual files and then build the config file based on that.  I
presume
that is what Studio does?

So, I find myself backing off a bit and thinking perhaps I would offer
an output switch for my existing gdaltindex program that would provide
XML config files instead of shapefiles.

Best regards,
