[Mapserver-users] analysis - editing ??

[Roberto Stecco]

hi list,
It's not long since I started working with GIS applications and I would like
to know if there's a way to edit the shape files (i.e. create a point, a
line or even a polygon) without using ESRI products. 
I use MapServer 4.01, PHP-MapScript and a PHP graphic tool (P.Mapper).
I'd also like to know if a deeper geographical analysis is possible. And how
can I do it.
Sorry for my english.    :-p 
Thanks.   

Roberto
