AbstractBecause of shrinking data-acquisition costs and increasing coverage of the Canadian territory, lidar technology has become integral to geomatics. In addition to its capacity to produce high-quality digital terrain models, lidar provides the opportunity to create new complementary data layers. The purpose of this analysis is to evaluate the potential of lidar data to extract cartographic objects other than elevation. Our results show that there is great potential in building extraction, as there are numerous related algorithms and tools. Extraction of the linear hydrographic network is equally promising, but it will require additional development effort. Surface-hydrography extraction yields mixed results, and requires significant development effort. The potential of transportation-infrastructure extraction is mixed as well, as no commercial or open-source solutions have been developed, and the additional development effort required is very significant. The potential of power-line extraction is moderate.
Summary(Plain Language Summary, not published)
This document presents a synthesis of a study on the potential of LiDAR data for the extraction of cartographic objects other than elevation. We present some methods and tools for the extraction of the buildings, the hydrographic network, the road network and power lines.
