CAST and the U.S. Forest Service Ozark-St. Francis National Forests (USFS) have developed a collaborative approach to documenting the existing conditions of Blanchard Springs Caverns. This inventory of existing conditions will assist the USFS in designing corrective work and maintenance in the future. Complete 3D inventories of the public entrances, service accesses, as well as all portions of the cave, including the natural entrance. The scanning team will use multiple high-density laser scanners throughout the cave system to capture all features.

The NSF-funded Plant Imaging Consortium (PIC) brings together experts in plant biology, radiochemistry, phenomics, imaging, and computational biology to apply high-throughput phenotyping and molecular imaging techniques to the study of plant stress biology. High-throughput phenotyping (HTP) allows breeders to screen large populations of plants quickly and efficiently, and to quantify numerous complex traits that are not obvious to the naked eye. Molecular imaging (MI) techniques such positron emission tomography (ie. PET scans) utilize radioactive, fluorescent, or luminescent probes to elucidate the physiological processes that govern stress tolerance or susceptibility in plants. Together, these bioimaging technologies have transformative power to link genotype to phenotype and identify genetic sources of stress tolerance for crop improvement.

The 3D Petit Jean project uses state-of-the-art, laser scanning technology to create 3D models of the bluff shelters and the rock art that was created in them by Native Americans hundreds of years ago. This effort aims to precisely document the dozens of pictographs and petroglyphs and the complex environment they were created in as well provide a means to help visitors locate and understand them. Indian Cave is not accessible to visitors, but because of its restricted size and limited number of motifs, it provides an interesting contrast to the larger Rockhouse Cave – home to the largest concentration of rock art in Arkansas with over 100 motifs. Rockhouse Cave is also the only rock art site in Arkansas with public access. Thousands of visitors explore this bluff shelter each year in search of these interesting images, but most walk away without finding a single one. Many are quite small and difficult to see even to someone who has located them before; however, even the largest figures remain hidden to the great majority of visitors in the vastness and complexity of Rockhouse Cave.

In June 2011, this NSF-funded, collaborative effort helped to preserve the first reported occurrence of theropod trackways, as well as numerous sauropod trackways, in The Natural State. The dinosaur trackways were exposed over an area of approximately 6000 m2 on a thin (ca. 0.5 - 0.7 m thick) limestone layer within the De Queen Limestone member of the Trinity Group (early Cretaceous Periods, approximately 120 - 115 million years old). CAST developed a website that presents an interactive visualization of the main portion of the trackway site (approximately 4200 m2) derived from the high-resolution LiDAR data. Viewers can zoom and pan to investigate tracks and trackways. The apparent illumination and shading can be altered using the check boxes in the legend to better highlight tracks and trackways; depending on their orientation, visibility of tracks and trackways can be enhanced by changing the apparent azimuth of illumination.

The CI-TRAIN project is a partnership of institutions of higher education to transform the practice of information technology services for enabling scientific discovery. The CI-TRAIN project was founded by institutions in Arkansas and West Virginia in a partnership that builds on common research in nanoscience and geosciences and leverages complementary expertise.

Researchers in the Center for Advanced Spatial Technologies at the University of Arkansas have traveled around the world using their advanced remote sensing technology to provide a 3-D perspective of archaeological sites and historic structures. Time Scanners showcases CAST laser-scanning experts collecting and analyze billions of measurements. They use the data collected by laser scanners to produce what is known as a 3-D point cloud. The six-part documentary series includes full episodes from the Egyptian Pyramids, St. Paul's Cathedral, Petra, Machu Picchu, the Colosseum and Jerusalem. Episodes are available online at http://www.pbs.org/program/time-scanners/.

The Hampson Museum Collection represents one of the world's most extraordinary collections of American Indian artistic expression as well as a major source of data on the lives and history of late pre-Columbian peoples of the Mississippi River Valley. The collections at the museum are the result of extensive excavations of the Nodena Site as well as excavations at other sites in the region by Dr James K. Hampson, as well as work by others including the University of Alabama and the University of Arkansas.
