Headstone Inventory and Scanning at Mare Island Naval Cemetery, California

Abstract: The National Cemetery Administration (NCA) tasked the US Army Engineer Research and Development Center, Construction Engineering Re-search Laboratory (ERDC-CERL), with inventorying and scanning the nonmilitary headstones at Mare Island Naval Cemetery. The cemetery is located in Vallejo, California, and is part of the Mare Island Naval Ship-yard historic district, which was listed concurrently on the National Register of Historic Places and as a national historic landmark in 1975. The research in this report will assist the US Department of Veterans Affairs (VA), NCA, with compliance with the National Historic Preservation Act of 1966 (NHPA). This report contains a list of headstones that need to be repaired or re-placed and a list of headstones that need to be corrected due to errors. Separate from this report, NCA will be provided with 3D models in .obj (for computer numerical control [CNC]) or .stl (for 3D printing) format. These formats are industry-standard CNC fabrication methods used to cut new stones. This technology will preserve the artistic elements of the stones that would be lost in an AutoCAD rendering process.
