XYZ data can be extracted from gINT and exported to a surface modeling program.If you have borehole coordinates in your project, you are sitting on a tremendous amount of surface information: Top of ground, top of bedrock, bottom of fill, water surface, top of contaminant zone, bottom of contaminant zone, top of material whose N value is greater than 25, etc. The east, north, and elevation or depth (XYZ) of the desired surface can be extracted from each borehole and exported in a format that Surfer®, RockWorks®, Surpac®, GenIO®, and many other surface modeling programs can read.
