Virtual Reality on the Owyhee? Almost.
Today, Valentine's Day, was a red-letter day for mapping on the Owyhee. NBMG recently obtained some very cool software and hardware for mapping in 3-D. With the help of digital photgrammetry and several other things I only vaguely understand, it is possible to build orthorectified and georectified stereo-models in the digital domain, map on them, and then export the lines (with z-values no less) into ArcGIS. Today, my colleague Nick put me through the preliminary ropes with some Owyhee images, and I am sold. Extremely cool, and not nearly as complicated as a PG-2 plotter to set up.
I plan on fine-tuning the Owyhee map with this device before the river trip. Note, if I have time, I can also extract a very accurate longitudinal profile for the river (or any feature for that matter). Stay tuned. I can even cut cross-sections if necessary...extremely freakin' cool.
