Because lidar so clearly and accurately delineates architectural remains, walls, foundations, house mounds, and roads and paths, even if these remains are disturbed or destroyed in the future, the evidence of where they are and how they are related to each other will be retained in the lidar record. Thus, this record not only helps to identify where the remains are, but it also allows archaeologists to monitor the remains over the whole site for deterioration due to either natural conditions (e.g. erosion) or vandalism, and to retrieve or reconstruct the remains if they are destroyed in the future. There is no other method that provides this kind of detail and accuracy at a comparable cost in time and money. C oNCLusIoN Lidar is ideal for archaeological surveys for the preservation and conservation of ruins. It documents existing conditions and serves as a permanent record of the existing conditions of the ruins at the time they were documented. The use of this technology can change the way a full coverage archaeological survey in areas densely covered with architectural ruins is conducted. Lidar allows for archaeological discoveries to be documented quickly and accurately and at a huge savings when in comparison with traditional survey techniques. Legacies is extremely confi dent that lidar will be used to collect remaining data at the archeological site as soon as possible. The technological advancements of lidar and its applications have grown quickly over recent years, including the support of new world capabilities such as the high accuracy of the data and the speed of collection. But for Legacies , lidar is actually serving the world with its fi ndings. 966 Oct ober 2011 A CKNoWLEDGEMENts Legacies of Resilience One of the great challenges for the 21st century is creating solutions to linked social and environmental change. Archaeology is uniquely poised to make a signifi cant contribution to this debate by helping to explain trajectories of socio-ecosystem evolution over long time scales. Legacies of Resilience is a long-term research project to promote the use of long-term coupled human/environmental records for conservation. Photogrammetric engineering & remote SenSing
