OC 2017 DEM Image Service

BY USING THIS WEBSITE OR THE CONTENT THEREIN, YOU AGREE TO THE TERMS OF USE. To acquire detailed surface elevation data for use in conservation planning, design, research, floodplain mapping, dam safety assessments, and hydrologic modeling. LAS and bare earth DEM data products are suitable for 1 foot contour generation. USGS LiDAR Base Specification 1.2, QL2. 19.6 cm NVA.This metadata record describes the hydro-flattened bare earth
digital elevation model (DEM) derived from the classified LiDAR data for
the 2017 Michigan LiDAR project covering approximately 907 square
miles, in which its extents cover Oakland County.This data is for planning purposes only and should not be used for
legal or cadastral purposes. Any conclusions drawn from analysis of
this information are not the responsibility of Sanborn Map Company.
Users should be aware that temporal changes may have occurred since this
dataset was collected and some parts of this dataset may no longer
represent actual surface conditions. Users should not use these data for
critical applications without a full awareness of its limitations.
Contact: State of MichiganDue to the large size of the data, downloading the entire county may not be possible. It is recommended to use the live service directly within ArcMap or ArcGIS Pro. For further questions, contact the Oakland County Service Center at 248-858-8812, [e-mail].

本数据集旨在获取精细地表高程数据，可应用于生态保护规划、工程设计、科学研究、洪泛区制图、大坝安全评估以及水文模拟等领域。
LAS格式及裸地数字高程模型（Digital Elevation Model, DEM）数据产品可用于生成1英尺间距等高线。本数据符合美国地质调查局（United States Geological Survey, USGS）激光雷达（Light Detection and Ranging, LiDAR）基础规范1.2版，等级QL2，标称垂直精度为19.6厘米。
本元数据记录所描述的，是经水文平差处理的裸地数字高程模型（DEM），其源自2017年密歇根州激光雷达项目的分类激光雷达数据。该项目覆盖面积约907平方英里，数据范围涵盖奥克兰县（Oakland County）。
本数据仅可用于规划用途，不得用于法律或地籍相关事务。基于本数据开展分析所得出的任何结论，均不由桑伯恩地图公司（Sanborn Map Company）承担责任。
用户需知晓，自本数据集采集完成以来，地表状况可能已随时间发生变化，部分数据可能无法反映当前实际地表情况。若未充分了解本数据的局限性，请勿将其用于关键应用场景。
