| 摘要： | The purpose of this project was to obtain, process, and develop a high-resolution highly accurate elevation data set of the Port complex using Light Detection and Ranging (LiDAR) technology. The applicability of the data set for feature extraction and GIS functionality was investigated for a subset of the Port area. This METRANS applied research project fell under the METRANS directive of data gathering, description and documentation to achieve the stated purpose of investigating, and developing a highly accurate elevation data set for use in a Geographic Information System that encompasses the Port complex. This research focused on the acquisition and processing of a highly detailed elevation dataset using Light Detection and Ranging (LiDAR) technology. LiDAR data are frequently used within geographic information systems (GISs) to obtain surface elevation values and to refine the boundaries of manmade surface features. |
