[mapserver-users] TIP: Breaking Up Large Images for TILEINDEX

[Tyler Mitchell]

FYI
I just added a note to the beginning of
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?CreatingTiles pointing users
to your excellent AVE for tiling shapefiles.  That's worthy of the wiki,
especially if you can put the AVE up there without HTML splitting the long
lines!.  Thanks Chip.

I've seen this topic come up a few times on the list, so I added something
to the WIKI-

http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?CreatingTiles

I often have images where a single image covers a large area (perhaps
something like a MrSID of an entire county). In order to make this
functional in MapServer, I convert to TIF, then break up the TIF into tiles
for use in a TILEINDEX.

What I put on the Wiki is an ArcInfo AML that takes an input image, breaks
it up into smaller images, creates the tileindex shapefile (using
gdaltindex), and indexes the shapefile (using shptree).

Anyway, sorry for the emphasis on an ESRI product, but I know that there
are
a lot of MapServer users out there who also use ArcInfo... so hopefully
this
will be useful.

BTW, if there's another way to do this... like using GDAL or something...
I'd love to know.
