Indexing of ShapefilesRUN=20

shptree shapefile.shp

at the command prompt=20

It will speed up the display of the shape file in mapserver.

  Subject: [Mapserver-users] Indexing of Shapefiles

  Hi all,=20

  I have several very large shapefiles that I wish to display.  =
Everything works fine, except that rending and querying take a _long_ =
time.  Does MapServer work with attribute indexes on shapefiles to speed =
up queries?  Spatial indexes to speed up queries?  I have read about the =
TILEINDEX but am not sure how this applies to a single large shapefile.

  Any help would be appreciated!=20

  Thanks,=20
