Demo 3d photo analysis: Trenta transect

Experimental 3d photo modeling with PM6. 3 photos taken from Trenta low-angle delta used to map set of control points and generate 3 corresponding camera locations. Vertical prism pole used for rotation and scaling. Second set of points mapped (but not used to build 3d camera location model) to generate transect. Layers used to group two sets of points. Table of transect points copied and pasted (could not be exported) to Excel and plotted crudely. Approx size is 30m horizontally and 30m vertically. Transect nicely reveals benches in exposure that are very hard to see in photos. Successfully demonstates 3d measurement method.
