<DIV><FONT face=Arial size=2>Tile Indexers,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> I'd like to resolve the tile-index problem
soon (v4.6?). To briefly re-state the problem:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The Current Situation:</FONT></DIV>
<DIV><FONT face=Arial size=2>=================</FONT></DIV>
<DIV><FONT face=Arial size=2>Paths to tiles are currently constructed by
Mapserver by appending various strings:</FONT></DIV>
<DIV><FONT face=Arial size=2> mapfile path
+ SHAPEPATH + tile item value + DATA </FONT></DIV>
<DIV><FONT face=Arial size=2>If any of the first three strings contain an
absolute path, the ones to the left of it are ignored.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This makes for not a very flexible (or portable)
data arrangement if you've got more than one index..</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>A Choice of Enhancements for a
Solution:</FONT></DIV>
<DIV><FONT face=Arial size=2>==============================</FONT></DIV>
<DIV><FONT face=Arial size=2>1. Mapserver would use the
same absolute-path rule as above, but if it doesn't resolve to an existing
file, would also try</FONT></DIV>
<DIV><FONT face=Arial size=2> mapfile path
+ tile index path + tile item value + DATA </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>OR</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>2. Add another keyword to the LAYER object:
TILEPATHPREFIX (or something better)</FONT></DIV>
<DIV><FONT face=Arial size=2> if present in the data LAYER, construct the
path as:</FONT></DIV>
<DIV><FONT face=Arial size=2> mapfile path
+ TILEPATHPREFIX + tile item value + DATA </FONT></DIV>
<DIV><FONT face=Arial size=2>(the same absolute-path rule would
apply)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Either solution would not break existing site and
should accomodate my wish to spread my data across file systems and Steve
W's to have the tileindex in the same spot as the data. </FONT><FONT
face=Arial size=2>Any thoughts? preferences?</FONT></DIV>
