The Colonel Armstrong Tree

This is the biggest tree (well, tallest) we've scanned and processed so far - the majestic, huge Colonel Armstrong Tree, in Armstrong State Park, CA. The tree is apparently 308 feet tall, although our lidar measurements suggest it's slightly shorter (90m or around 290 ft). Either way, it's MASSIVE. The point cloud is incredible, particularly the detail of the lower trunk. Andy has left the sign in at the lower part of the point cloud for scale - the sign is about 1.5m high.

Here are some quick screengrabs of the point cloud showing the amazing detail.

Finally, here's the link to the Sketchfab point cloud. I can't get the smile off my face when I look at this. For anyone who wants to find out more about these extraordinary trees (and they really have some amazing ecological secrets) I thoroughly recommend Richard Peston's The Wild Trees, an account of a band of climbers, ecologists and enthusiasts like Steve Sillett and others, pioneered the climbing, measurement and understanding of these trees in the 1980s and on.
