tile problem: loadLayer(): Unknown identifier. (INDEX)

[Joel Schlagel]

hi!
i think i'm missing something on tiling maps.

i've got a state index cover, and tiger road files for each state, and this
simple template:


NAME road_tile
STATUS ON
SIZE 600 600
EXTENT -82 31 -81 32
UNITS DD
IMAGECOLOR 100 100 150
TILE "/s7/tiger/road/"

WEB
  IMAGEPATH "/home/httpd/html/tmp/"
  IMAGEURL "/tmp/"
  TEMPLATE "z.html"
END


LAYER   
  NAME "road"
  INDEX "/s7/tiger/road/road_index"
#  DATA "/s7/tiger/road/ga"
  TYPE line
  STATUS DEFAULT
  CLASS
    SYMBOL 0
    COLOR 248 248 248
  END
END 


Mapserver returns the error:

  loadLayer(): Unknown identifier. (INDEX) 

with this template.  i've got the same problem with 3.3.002 and 3.3.006.

any suggestions would be greatly appreciated!

thanks

mapserver rocks!

Paul,

  As long as you don't want to query the data in the tiles, you
can use the tiling feature in MapServer.

1.  Create a shapefile containing the outlines of the counties
2.  Create a column in the shapefile with the name of LOCATION
3.  For each county outline shape in the shapefile, enter the filename
     of the county shapefile in the LOCATION column (leave off the
     .shp )
4.  Edit the "map" file.   Add an entry for TILE at the top.   This
     contains the path to the directory containing county files.  It is
     prepended to the name in the LOCATION column to build the
     full path to the shapefiles.

    Add a  LAYER entry with an INDEX entry.  The index is the name
    of the shapefile you created in step 1.

A couple of notes about tiles:
    1. The tile index shapefile and the "data" shapefiles must be in
        the same coordinate system.
    2. Mapserver will not query data in tiled files.
