ABSTRACT: Surficial and bedrock geologic maps have a useful potential for state and national geologic surveys to produce map products which serve as a value-added deliverable for a variety of stakeholders. The production of these derivative products was facilitated by the three-dimensional capabilities and enhanced geostatistical exploratory tools within many geographic information systems (GIS). Many GIS software packages can render three-dimensional visualizations using spatially-distributed point data. We used recently released 0.7-meter LIDAR, private well data, and ESRI's "Geostatistical Analyst" tool, to create derivative maps depicting surficial overburden, bedrock topography, and a potentiometric surface. These products demonstrate the relevance and usefulness of creating three-dimensional visuals in conjunction with typical two-dimensional map products. Three-dimensional visualizations have particular use with regards to town managers and planners, who may be relatively unfamiliar with traditional geologic map products and can better visualize and interpret relationships between surficial overburden and groundwater resource potential.
