Flip, could you describe what solving a survey network entails and how it would appear visually? I've just returned from the second meeting og X3D Earth working group who have big amibitions on the 3D visualisation side and an open specification and an excellent Java open source implementation. Please tell us more... Cheers Peter Strømberg www.hypergis.com

Dibner Sent: 21 April 2007 00:45 To: [email protected] Subject: [Geowanking] Open-source least squares network solution? Hello all. I have been looking for some open source code that solves an arbitrary survey network in 2D. Least squares solution, with the ability to weight points, would be ideal. 3D wouldn't hurt either, but isn't necessary. I've been looking for a while, and found nothing that suits, or even comes close. Any pointers? This isn't readily available through any of the "well-known" packages like GeoTools, GRASS, PostGIS etc., is it? Thanks, Flip Phillip C.
