Structure-from-Motion derived point clouds and orthomosaic images of reference sections of the Silurian units including the Rose Hill Formation, Keefer Sandstone, McKenzie Formation, Bloomsburg Formation, Williamsport Sandstone, Tonoloway Limestone, and the Keyser Limestone in Western Maryland
Description
This dataset consists of Structure-from-Motion (SfM) - derived point clouds and highly detailed orthomosaic images of two exposures covering the the Rose Hill Formation, Keefer Sandstone, McKenzie Formation, Williamsport Sandstone, Bloomsburg Formation, Tonoloway Limestone, and the Keyser Limestone. For each railway exposure, two datasets are published: an orthomosaic raster image and a point cloud. The orthomosaic raster image is a vertical outcrop orthomosaic constructed from multiple orthophotos to create a geometrically rectified image. This facilitates a detailed visual inspection of the stratigraphic succession outside of a GIS environment, unlike georeferenced orthomosaics derived from aerial imagery.
