Abstract

In the early stages of the U.S GeoFramework Initiative, the Kentucky Geological Survey has aggressively pursued multiple products to support KGS priorities and the USGS NCGMP effort at 3D compilation for the nation. The goal of nationwide 3D compiled from USGS and SGS sources is compatible with the KGS internal goal of compiling and developing a flexible, updateable, and accessible three-dimensional database of geological information. In the first few months of the effort, the KGS has successfully developed a statewide 3D fault model from 1:24k surface mapped faults, an inventory of >195 3D subsurface contact surfaces from various published sources (>14 of which are statewide or basinwide), a statewide set of >145 reference geophysical logs with updated and standardized stratigraphic tags, and a comprehensive review of stratigraphic discontinuities with our 2D 1:24k digital geologic map data (with GIS delineation and appropriate metadata). All of these data products will be available for integration into regional or national 3D compilation projects. In addition to the database products, KGS staff are documenting successful and unsuccessful work flows to better assist other SGS organizations planning to embark on similar projects. The majority of the work is being completed using ESRI Arc Pro and Arc Online. Web visualization of the 3D surfaces has been through Arc Online and a custom-tool web interface, designed with assistance from staff at the Illinois State Geological Survey. The ongoing and rapid development of multiple tasks has allowed the KGS to quickly develop staff proficiency at developing and using the 3D data and associated software, and is better position our organization and staff for future 3D work.
