Elevation Contour Lines for King County - 100 Foot Index Contours

For more information about this layer please see the GIS Data Catalog. One hundred (100) foot interval elevation contours for King County, derived primarily from 2021 lidar. The 100 foot contours are a subset of the 5 foot contour layer.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，请参阅地理信息系统（GIS）数据目录。本数据集为金县（King County）100英尺间隔的高程等高线，主要源自2021年激光雷达（lidar）数据。该100英尺等高线是5英尺等高线图层的子集。此等高线间隔是在源数据的垂直与水平精度，以及通用制图与分析产品的需求之间达成的最佳权衡。该数据可合理呈现地表的整体形态，可用于识别总体地貌、坡度与高程。本等高线仅作为地表形态的解译成果供参考使用，不可替代专业土地测绘的需求。
