A grid of the horizontal gradient of the reduction-to-the-pole (RTP) magnetic intensity for the Kedgwick 1999 survey.
A grid of the horizontal gradient of the reduction-to-the-pole (RTP) magnetic intensity for the Kedgwick 1999 survey.This dataset represents the horizontal gradient of the RTP magnetic intensity for the Kedgwick airborne magnetic survey in New Brunswick. The RTP_Hgrad highlights lateral changes in magnetic intensity, helping to delineate edges of magnetic sources, geological contacts, and structural boundaries. The dataset is provided in NB Stereographic Double, NAD83.The RTP_Hgrad grid was created from the Kedgwick 1999 survey by microlevelling the TMI (Mag_Miclev), applying reduction-to-the-pole processing, and then computing the horizontal gradient of the RTP grid. The final grid is provided in NB Stereographic Double, NAD83.Data created Sept 2025.
