Don,
I have a tiled index of NTS mapsheets (similar to the quads in the US)
the attached file
contains the index. I then use the table columns to select each of my data
themes. I have a dummy
shapefile for map tiles which do not have a file for that layer. The dummy
needs to have extents which cover the whole map area.
LAYER
NAME "lakes"
TYPE POLYGON
STATUS DEFAULT
MINSCALE 150001
MAXSCALE 600000
TILEINDEX NTS_NFLD_250
TILEITEM WATERP
CLASSITEM DESCRIPTIO
CLASS
EXPRESSION ('[FEATURE]' eq 'WABOFW' OR '[FEATURE]' eq 'WARI' OR
'[FEATURE]' eq 'WAFL' OR '[FEATURE]' eq 'WAFA')
COLOR 255 255 255
OUTLINECOLOR 142 205 247
END
END # Layer
LAYER
NAME "Water"
TYPE LINE
STATUS DEFAULT
TILEINDEX NTS_NFLD_250
TILEITEM WATER
MINSCALE 150001

EXPRESSION ('[DESCRIPTIO]' ne 'Virtual Line')

END # Layer
LAYER

END
END # Layer
