This digital product is a compilation of surficial geological data of the Halifax Metropolitan area which was defined by Dan Utting using a LiDAR derived bare-earth hillshade model. The LiDAR data was collected by PHB Lasermap, and provided by Halifax Regional Municipality. The data was used to create Open File Maps OFM ME 2011-001 to 2011-012, compiled by D. J. Utting, 2011. The digital product was created by Geoscience and Mines Branch staff at the Department of Energy and Mines. The digital product contains layers for geological features such as: age dates, drumlins, eskers, geological contacts, surficial geologic units, ice movement, moraines, meltwater, neatline, station locations, and large aggregate quarries.
