Elevation Contour Lines for King County - 5 Foot Contours

For more information about this layer please see the GIS Data Catalog. Five (5) foot interval elevation contours for King County, derived primarily on 2021 lidar. Above 1000 feet of elevation, the contour interval changes to ten (10) feet for legibility and drawing performance.The contour interval represents a best compromise between the vertical and horizontal accuracy of the source data and the need for a general use cartographic and analysis product. The data provide a reasonable depiction of the general shape of the land, useful for determining general landform, slope, and elevation. These contours are provided only as an interpretation of the earth's surface for reference use and do not replace the need for a professional land survey.如需了解该图层的更多信息，请查阅地理信息系统（GIS）数据目录。本数据集为金县（King County）5英尺等高距的海拔等高线数据，主要基于2021年激光雷达（lidar）数据生成。当海拔高于1000英尺时，为提升可读性与制图效果，等高距调整为10英尺。该等高距是在源数据的垂直与水平精度，与通用制图及分析产品的需求之间达成的最优折中方案。本数据可合理呈现地表的整体形态，可用于识别大致地貌、坡度与海拔高度。本等高线仅作为地表形态的解译参考资料，不得替代专业土地测量工作。
