Contours 2 ft (2023 LiDAR)

Contours derived primarily from the OLC Willamette Valley 2023 Lidar project point cloud, collected July 21-22, 2023. The point cloud for the 2021 project was used for the portion of the city along I-5 since it was not covered in the 2023 project.本数据集的等高线主要源自OLC威拉米特谷2023年激光雷达（Lidar）项目点云，该点云采集于2023年7月21日至22日。鉴于I-5沿线的城市区域未被2023年项目覆盖，该区域的等高线采用了2021年项目的点云数据。
