A georeferenced (gps) grid with 10m markings was laid out across a shale formation in SW South Dakota. Aerial photographs were taken ~30m above ground using a GoPro HD camera fixed to a helium balloon. Our goal is to reference and rectify the images by identifying visible cones with their GPS coordinates, which are converted to UTM.First efforts to identify control points on images resulted in loss of image during rectification. The UTM coordinates are 1984 WGS, and the site is located in Zone 13N. We want to use the resources of the Center for Earth Observation to properly rectify these images then construct a mosaic image of the site.
