Elevation Contours

Suitable Use This dataset can be used to view elevation contours derived from lidar planimetric data collected in 2020. Limitations on Use The data is derived from lidar data and may not be accurate or may be out of date due to changes since collection date. Data Dictionary ObjectID - Numeric unique identifier with no special meaning. Elevation - Elevation above sea level in US feet. Contour Type - Indicates if the contour line is primary or intermediate. Shape - Geographic data in state plane coordinates (WKID 103512). Length - Approximate length of feature in US feet. Update Interval This dataset is updated every 4 to 6 years. Maintained By This dataset is maintained by the Information Technology Department of the City of Oklahoma City. Contact Open Data Feedback适用范围：此数据集可用于查看基于2020年采集的激光雷达（lidar）平面测量数据生成的海拔等高线。 使用限制：本数据源自激光雷达数据，因采集日期后发生的地表变化，可能存在精度不足或数据过时的情况。 数据字典： - ObjectID：无特殊含义的数值型唯一标识符。 - Elevation：以美制英尺（US feet）计量的海拔高度。 - Contour Type：用于标识等高线为主等高线或辅助等高线。 - Shape：采用状态平面坐标系（WKID 103512）的地理空间数据。 - Length：以美制英尺计量的要素近似长度。 更新周期：本数据集每4至6年更新一次。 维护单位：本数据集由俄克拉荷马城信息技术部（Information Technology Department of the City of Oklahoma City）维护。 联系方式：开放数据反馈
