[Mapserver-users] SHPTREE Odd behavior

[Carl Anderson]

I suspect that this is not Shptree related but that you have "Null" 
shapes in your shapefile.  Especially due to the relatively old version 
or mapserver you are running.  lok for a discussion on Null shapes in 
the HISTORY.TXT file

you can winnow the "Null" polygons by (I assume you have access to 
arcview)
selecting for "[shape].aslist.count = 0" and deleting those records.

Arcview writes Polygons with no vertices as a shape type Null instead 
of a polygon shape type.  
if you still are having problems can you provide more info?.
