[mapserver-users] Ed's Rules for the Best Raster Performance

[Fawcett, David]

Better yet, 

Add your comments to:

http://mapserver.gis.umn.edu/docs/howto/optimizeraster

and 

http://mapserver.gis.umn.edu/docs/howto/optimizevector

I had always thought that all we needed to do to make these pages great
was to grok the list for all of Ed's posts...

David.

Subject: [mapserver-users] Ed's Rules for the Best Raster Performance


In honor of Ed's imminent retirement from the Mapserver Support Group,
I've put together "Ed's List for the Best Raster Performance":


#1. Pyramid the data 
        - use MAXSCALE and MINSCALE in the LAYER object.

#2. Tile the data (and merge your upper levels of the pyramid for fewer
files).
        - see the TILEINDEX object

#3. Don't compress your data
        - avoid jpg, ecw, and mrsid formats.

#4. Don't re-project your data on-the-fly.

#5. Get the fastest disks you can afford.


(Ed, feel free to edit...)
