|
A grid of the horizontal gradient of the reduction-to-the-pole (RTP) magnetic intensity for the Columbia 2000 survey.This dataset represents the horizontal gradient of the RTP magnetic intensity for the Columbia 2000 airborne 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 Columbia 2000 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. |
