What is Trimble up to?

I am really curious about what Trimble is up to and where the company is headed in the future. Trimble leading manufacturers of mapping and survey grade GPS equipment and software.  Earlier in the month it was announced that Trimble acquired the company Gatewing, developers of a streamlined UAV / computer vision 3D mapping system, press release here.  Today I found that Trimble is also buying Google Sketchup, Sketchup blog post here and Trimble press release here.

A 3D mapping company and a community-based 3D modeling program/warehouse in one month -- clearly massive 3D surveying and mapping are at the top of the list for Trimble.

I think this is very exciting, but what comes next?  More importantly perhaps, where do trees, vegetation and the non-built parts of local ecosystems fit into this?

The Algorithmic Beauty of Plants

In searching for research related to the structure and architecture of trees and canopies, I came upon the book The Algorithmic Beauty of Plants and the research of Dr. Przemyslaw Prusinkiewicz and his Algorithmic Botany lab in the Department of Computer Science at the University of Calgary.  All I can say is, 'Wow!'

The image at left is from a 2009 paper on procedural, self-organizing reconstructions of tree and forest landscapes.

Dr. Prusinkiewicz's research spans over two decades and his website includes published algorithms for procedurally generating 3D, colored, and textured plants.  Some of the figures in these papers look amazing.

I look forward to looking more into Dr. Prusinkiewicz's research for inspiration and insights in support of my own research with computer vision remote sensing based reconstruction of canopies.  Some of Prusinkiewicz's work covers the use of point clouds to 

represent tree structure, so I am definitly interested in learning more about that data model.
