Role of LiDAR in archaeology

PNAS u August 7, 2012 u vol. 109 u no. 32 u 12837–12838 www.pnas.org/cgi/doi/10.1073/iti3212109 Radiocarbon dating enables archaeologists to probe relationships between ancient sites, peoples, and cultures, allowing them to determine the absolute dates and ages of past events and settlements. Arlen Chase et al. (pp. 12916– 12921) report that a widely used laser-based remote sensing tool known a...

Forest Delineation Based on Airborne LIDAR Data

The delineation of forested areas is a critical task, because the resulting maps are a fundamental input for a broad field of applications and users. Different national and international forest definitions are available for manual or automatic delineation, but unfortunately most definitions lack precise geometrical descriptions for the different criteria. A mandatory criterion in forest definit...

Airborne Lidar Data Processing and Information Extraction

February 2007 109 continued on page 110 Lidar is changing the paradigm of terrain mapping and gaining popularity in many applications such as floodplain mapping, hydrology, geomorphology, forest inventory, urban planning, and landscape ecology. One of the major barriers for a wider application of lidar used to be the high cost of data acquisition. However, this problem has been greatly alleviat...

Dem Generation from Airborne Lidar Data

Airborne Lidar (light detection and ranging) sensors provide dense height information of large areas in an efficient manner. But for the production of digital elevation model (DEM) from the point cloud, the filtering of the point cloud should be carried out in order to remove points representing surface of non-ground objects. According to the deficiencies of slope based method, a novel filterin...
