Service Description: This dataset represents the Shape Index derived from the gravity tensor of the SWN_NBStereo (Lantern) FTG/AGG survey, gridded at 25 m resolution in NAD83 NB Stereographic projection.The dataset contains the Shape Index calculated from the reconstructed gravity tensor of the SWN_NBStereo survey. The Shape Index quantifies the local curvature and geometry of the gravity field, highlighting shallow structural features such as faults, lithological contacts, and intrusive bodies. This high-resolution dataset is useful for detailed structural interpretation and mineral exploration and is provided as a 25 m grid in NAD83 New Brunswick Stereographic projection.This raster was produced by constructing the gravity tensor from the SWN_NBStereo FTG/AGG profile data processed with a density of 2.8 g/cc, gridding the tensor at 25 m using a tensor-interpolation algorithm, and calculating the Shape Index following the method of Cevallos (2014). The final grid was exported in ER Mapper (.ers) format.Data created Sept 2025.
