Arc Hydro GW Data Model
Borehole Log Table Combining the well geometry (x, y) and the vertical data stored in the BoreholeLog table we can describe a set of 3D geometries (x, y, z)

Additional workflow – image registration • Start from existing cross section images
• Load and register the images to an existing SectionLine • Wizard helps create necessary features (grid lines, panel dividers, panels) based on the image registration process USGS professional paper 1731
Image registration wizard Register the image using vertical and horizontal lines
Image registration wizard Result is a new data frame with registered image + XS2D feature classes
