|
A grid of the first vertical derivative of the reduction-to-the-pole (RTP) magnetic intensity for the Tobique River 1985 survey.his dataset represents the first vertical derivative of the RTP magnetic intensity for the Tobique River airborne magnetic survey in northern New Brunswick. The RTP_1VD emphasizes near-surface magnetic sources and sharpens anomaly edges, aiding detailed geological and structural interpretation. The dataset is provided in NB Stereographic Double, NAD83.The grid was created from the Tobique River 1985 survey by microlevelling the TMI, applying reduction-to-the-pole processing, and then calculating the first vertical derivative of the RTP grid. The final grid is provided in NB Stereographic Double, NAD83.Data created Sept 2025. |
