LiDAR 3D digital mapping of palaeontological sites
The use of LiDAR, 3D digital mapping, of outcrops in the field. Current research collaboration include Consorci Ruta Minera (Barcelona), whom we are developing a 3D digital map of a large outcrop of dinosaur trackways (circa 3000+) in the Spanish Pyrenees. Fieldwork also includes LiDAR digital outcrop surveys of Lance and Hell Creek Formations in Wyoming, Montana, North and South Dakota, working with the Marmarth Research Foundation (North Dakota).
The modern technologies of GPS, satellite remote sensing, digital photogrammetry, videogrammetry and LiDAR high definition surveying are providing revolutionary approaches to geological outcrop, palaeontological and geoconservation research. These techniques can be used in association with traditional field methods to provide qualitative and quantitative 3D outcrop data.
The Palaeontology group works with the Basin Studies group to access a Riegl LMS-Z420i LiDAR and Trimble ProXR GPS system that is ideal for geological applications. The GPS provides an efficient and accurate tool for the measurement of points and linear features at accessible outcrops. The LiDAR system however, allows rapid, high resolution, digital mapping of otherwise inaccessible outcrops at ranges from just a few metres to a kilometre. Scans from many different LiDAR survey stations can be merged to form seamless geo-referenced photo realistic outcrop models.
The LiDAR data provides detailed spatial and geometrical information that can be used to measure and map even small-scale sedimentary architectures, fault systems and other subtle features over large areas. The data can be classified according to facies and used for palaeoenvironmental modeling and geoconservation appraisals.
