Mobile LiDAR / Point Cloud Veiwer

Just a quick post on something I found just in time for AGU, a mobile LiDAR / Point Cloud viewer app for Android (Google Play). I've been searching for an app like this since I started creating 3D datasets.


It works best with LAS files, which for Structure-from-Motion point cloud data you can export LAS files from CloudCompare. It seemed to have a problem with UTM coordinates (probably to a decimal precision cut off), but if you export the data in a "local" coordinate system it works beautifully. I also tried it on some OpenTopography LiDAR data and it works just fine.

Geography Awareness Week

Just a few action shots from the stream table demonstration I helped with as part of the U of O's Geography Awareness Week. Thanks to Jessie for organizing and Sarah and Alanna for being co-demonstrators.

Kinect Field Mapping Trial

Just a quick demo of field mapping with a Microsoft Kinect. We set out to test the Kinect outdoors. Luckily, Scott Creek is under a wonderful canopy of Cascade forest, which was good for the Kinect's infrared depth sensor. Check out the video of collecting and processing the data in the field and below is an interactive 3D point cloud. We used Faro Scenect to collect and process the Kinect data. More to come on this later...

Converting DEMs to STL files for 3D printing

Ever since we got a 3D printer in the Geography Department at the University of Oregon, we've wanted to print out topographic models. Thingaverse user Markus Fussenegger (mfussi) has a nice compact Java program, Heightmap to STL, for converting height map images into STL files for 3D printing. Markus's program is available on Sourceforge through Thingaverse (http://www.thingiverse.com/thing:15276).

This is just a quick tutorial on how I got his code up and running on my Windows 7 machine...
