New Pages: Software and Publications

Now that I'm down with my dissertation, it's time to make some improvements...I've added two new pages to my site: Publications and Software. I'll be updating these periodically with my pubs and some of the software/code that's floating around.

Both of these new pages have been added to the navigation tabs at the top of the page.

LiDAR datum transformations

A stretch of the Roaring Branch of the Walloomsac River near Bennington, VT. So, I've been helping get an Earth Science graduate student going on some change detection work with some lidar data from the State of Vermont. As we were going through some of the sample datasets an interesting, yet not surprising, realization came over us...several of the datasets were in different projections. So we set out to find a simple way to convert the raw LAS files from lovely Vermont State Plane coordinates in feet (both horizontal and vertical) to the infinitely useful UTM with meters all around.

There are several options out there, but I rediscovered an old standby, the National Geodetic Survey's VDATUM tool.
