In Arc Hydro Groundwater, tabular information from well logs about the “contact points” at which the well driller encountered each new subsurface layer is translated within ArcGIS into a 3D vertical representation of the borehole.
Cross-sections can be drawn by connecting a sequence of boreholes or by cutting directly through a “geovolume” representation of the 3D structure of these hydrogeologic units.
A special extension of the Arc Hydro Groundwater tools called Subsurface Analyst can be used to perform these functions.
