We spent most of November 2018 in Botswana studying elephant habitats using fodar, expanding on our work in 2017. This blog summarizes our 2018 mapping work from acquisitions to data validation, [...]

Here I share the first processing results of my 1002 Area topographic mapping effort and find these data suitable for measuring topographic change at the centimeter level. I also have a few [...]

This summer I mapped all of the Arctic National Wildlife Refuge’s 1002 Area, as well as all of the glaciers draining into it, covering about 8000 km2 in total. The map resulting from these [...]

In the global conflict for dominance over the shape of the earth’s surface, plate tectonics has been the clear victor over erosional processes in the 1002 Area of the Arctic National Wildlife [...]

As of July 26, not only are the winter 2018 seismic tracks still visible at Pt Thompson, the depressions they left behind are still measurable topographically with fodar.  I believe that it is [...]

In a little over a month after my first flight, I’ve now completed about 95% of acquisitions of the best topographic map ever made of the Arctic National Wildlife Refuge’s 1002 Area, [...]

Week Two of my mapping efforts in the 1002 Area ended with acquisitions about 33% complete, covering ~2000 km2 at 5″ resolution by taking ~50,000 photos in ~7000 miles of flying.  My goal [...]

Last Sunday (24 June 2018), on my first day of creating the best topographic map ever made of the 1002 Area of the Arctic National Wildlife Refuge, I was fortunate to find that seismic [...]

Turner and I spent a long weekend in Talkeetna, attending the 8th Annual Talkeetna Fly In, and used the opportunity to test some new fodar upgrades as well as participate in an opportunistic [...]

This blog will hopefully go a long way towards dispelling the myth that fodar cannot be used to measure ground topography beneath a tree canopy.  Whether it is the best tool for the job depends [...]
