GT-Grid
Gradient Tensor Gridding
Higher Resolution - Greater Accuracy - Lower Cost
The GT-GRID process combines measured horizontal
gradient with total field to produce a grid that is constrained by all three
measurements. This integration of the gradient information into the
gridding process improves the resolution and accuracy of the magnetic map.

The example below
is taken from Ontario Geological Survey Magnetic Datset 1040 of the
Kapuskasing area in Northern Ontario. This illustration presents the total field and calculated vertical gradient maps as published by the OGS on the left together with their
GT-GRID counterparts on the right.
