We are moving fast with our Em4 work, partly in preparation for GSA in Minneapolis, where I’ll be giving a talk about use of color coded by size (CCS) media and also Close Range Photogrammetry (CRP). We’re also now trying out a Gigapan system.
Here you can see the draft video of a run last week in which we built a delta. We lowered base level (the standpipe) to cut channels through it, and then sliced it to show various stratigraphy. I’m very happy with the results! The music is just a placeholder, if it bothers you, turn it down, there is no narration.
You’ll find a Gigapan of the sliced sediment here: http://gigapan.org/gigapans/85919/
And here’s an older video showing details of the CCS. Note that we’re experimenting with a finer red colored fraction added since this video was made.
