Upstream view of exposed rock in the concrete spillway overlay.
Screen capture of the photogrammetric model. The colored translucent disks are "joint halos" that represent discontinuities in the rock mass. The software generates these joint halos, and different colors indicate different joint sets (joints that are oriented in similar dip and dip directions).
