The Geologic interpretation of the GLORIA images found in the atlas, I-1864-A,B, was digitized and Arc/INFO coverages created. Those coverages were combined to create a single, pseudo-color coded interpretive map/image for DDS-15. Unfortunately, the coverages were subsequently lost. Rather than redigitize the mosaics, the decision was made to recreate the coverages based on the image from DDS-15. The union of all the polugons in the geologic interpretation were combined to create this GLORIA coverage shapefile.
