LiDAR, which stands for Light Detection and Ranging, is a リモートセンシング technology that uses laser pulses to measure distances between the sensor and the Earth’s surface. By emitting millions of laser beams per second, LiDAR captures precise 3D information about the environment, including terrain, vegetation, and man-made structures.
The data collected by LiDAR is typically processed to create high-resolution digital elevation models (DEMs) and 3D point clouds, which represent the spatial distribution of features within a surveyed area. These models are invaluable in various fields such as geography, forestry, 都市計画, and environmental monitoring.
LiDAR systems can be mounted on aircraft, drones, or ground-based platforms, enabling them to cover large areas quickly and efficiently. The resulting data can be used for applications such as flood modeling, vegetation analysis, infrastructure management, and archaeological site mapping. Additionally, advancements in LiDAR technology have made it increasingly accessible, allowing for the integration of this data into geographic 情報システム （GIS）やその他の分析フレームワーク。
全体として、LiDARデータは重要な洞察を提供し、サポートします。 decision-making in both public and private sectors, enhancing our understanding of the natural and built environments.
