The National Park Service is creating a digital map of Carlsbad Caverns National Park to help with repairs and maintenance projects.
The agency is using light detection and ranging equipment to digitally map out the entire cave system in southern New Mexico down to the millimeter, the Carlsbad Current-Argus reports .
The Center for Advanced Spatial Technologies at the University of Arkansas is helping with the $186,000 project, which began in 2015. Staff is shooting images and collecting data using laser lights and measuring the reflected light with hundreds of sensors."It's like a big 3D set of data," said Julie McGilvray, cultural resources program manager at Guadalupe Mountains National Park."It's useful for so many things.
She used the ranging equipment data to help create a cultural landscape inventory focusing on viewshed, which is the visual experience a person has while in a certain geographic location. "In order to preserve it, you need to know what you're preserving," Gorman said."A helps to formalize that in a way that is very comprehensive and detailed. It allows you to see the cave from without. This allows you to view the cave in 3D from an outside location."
