Hi;
I've got a question that relates to Ticket #75: Feature Request: 2-level
spatial index ("TileIndex" in UMD Mapserver) - a feature that is planned for
Mapnik in the future.
I'm working for a company that has used MapServer in the past, and is
considering migrating to Mapnik to generate map tiles. As part of the old
system, there are several data sets that were configured to use the
TileIndex capability of MapServer. tile4ms was used to break the original
data set into localized shapefiles, each with its own spatial index file
(.qix, created by shptree). The filenames of these data sets are summarized
by a tile index shapefile that includes the file pathnames as an attribute
named "LOCATION". There aren't many localized files; the world is covered
by only 73 of them. The tile index file is then referenced in the MapServer
stylesheet.
I'd like to convert this to a system that Mapnik can use currently. I was
thinking of importing all the shapefiles into a PostGIS database, and doing
the spatial indexing with it, but I'm a total newbie with databases. I
think that a database view might take the place of the tile index file, but
I don't know how to set it up. Anybody have some suggestions about how this
could be done?
Thanks,
Liz
