AAPG Datapages and the AAPG GIS Publications Committee wish to thank Dr. David Rajmon for allowing his Global Impact CraterGIS project to be posted on Datapages' GIS Open Files page, thereby making it available to the public as a free download.
You can read more about the project and its source here. Join Dr. Rajmon's Impact Crater group on LinkedIn here.
Please note: This project is available in three formats: Shapefile, Geodatabase, and ArcReader.
(The Shapefile and Geodatabase formats require GIS software; ArcReader uses free software that can be downloaded here.)
