Paul,
Have a read regarding TILEINDEXes
(http://mapserver.org/optimization/tileindex.html). It may be useful to
have one TILEINDEX (and one layer) per scale group (so a total of 6
layers). The TILEINDEX will provide a spatial limitation [min/max x/y]
per file.
Best Regards,
Brent Fraser

Hi,
I've just started using Mapserver and have a question, that could help
me to cut corners.
1)I have a lot of S57 charts in different scale groups 1-6.
2)It should be simple to maintain the map data (a lot of upgrades).
3)Of course, it should be fast.
Strategy of today:
I have the original data stored in the original format on ram disk. I
have one map file that INCLUDEs all "layer" files (one per chart).
The layer files defines the all the interesting chart features
(layers) and the max scale.
I was thinking that I only shall use max scale, not min scale, because
if I don't have a chart with a larger scale a certain position when I
zoom in, then I shall at least see a chart. Even if has a to small
scale for this zoom. I don't have any spatial restrictions on each
layer or layer file, just for the map file -90, -180, 90, 180 (i.e no
limits)
Is it possible to have spatial limitations on a layer?
When I use this strategy the map server chokes then I zoom in too much.
I can see that the map configuration could be done in a lot of
different ways,
How would your strategy be?
Kind regards,
Paul
