That is huge. the open source solutions and devlopers never cease to amaze me!<br>

Accessing SDE data in GRASS via OGR would be astounding.<br><br><div><span class="gmail_quote">On 12/5/05, <b class="gmail_sendername">Dylan Beaudette</b> <<a href="mailto:dylan.beaudette@gmail.com">dylan.beaudette@gmail.com
