2005 San Diego Urban Region Lidar

2005 Lidar coverage over cities of San Diego, Poway, and Chula Vista. These lidar data are part of a larger project that collected lidar for a number of coastal cities in San Diego County. Data from the same 2005 lidar project may be available for other cities beyond San Diego, Poway, and Chula Vista but those cities should be contacted individually. Lidar data were collected in conjunction with a three-inch resolution imagery collection for San Diego, Poway, and Chula Vista. Lidar products include LAS files and ASCII canopy data at a minimum; Poway adds two foot contours. Point spacing of LAS data is approximately one meter. Data have also been resampled to a one-ninth arc second grid (three meter spacing) and placed within the National Elevation Dataset.

2005年激光雷达（LiDAR）覆盖数据集涵盖圣迭戈、波韦与丘拉维斯塔三座城市。该批激光雷达数据属于一项更大规模项目的组成部分，该项目针对圣迭戈县内多座沿海城市开展了激光雷达数据采集工作。同一2005年激光雷达项目的采集数据或许也可向圣迭戈、波韦、丘拉维斯塔之外的其他城市提供，但需自行与对应城市接洽获取。上述三座城市的激光雷达数据采集工作同步配套了3英寸分辨率的影像采集任务。激光雷达产品至少包含LAS文件与ASCII格式冠层数据；波韦市额外提供2英尺等高线数据。LAS数据的点间距约为1米。此外，所有数据已被重采样至1/9弧秒网格（对应3米间距），并纳入国家高程数据集（National Elevation Dataset）。
