Generalizing shapefiles...

[Trevor Banister]

This looks quite usefull. It runs without the overhead of Arcview/Avenue and
will run from the command line.

The only scary part is the section that reads:

system("rm $outfile.*");

I often have map files and html files that start with the same name as my
shapes. The script looks like it will wipe out these and anyhing that starts
with $outfile.

how about a little safer code that just nukes the output files.
system("rm $outfile.shp")
system("rm $outfile.shx")
system("rm $outfile.dbf")
...
etc..

Just my $0.02,

Trevor

Greetings: In case anyone is interested I ported the shapefile
generalization Avenue
script (Douglas-Peuckert Algorithm) hat comes with ArcView to MapScript.
It's little 
slower, but then again it's free. On test coverages I've processed it
produces the 
exact same output as the Avenue version. I need to add a progress meter,
but that's 
about it. It requires version 3.3.010.

I hope someone will find it useful.
