2023 Contours - 5ft

Polyline dataset that displays 5 foot contour intervals for the City of Winchester. Dataset is a subset of the 1 ft contours. Contours were generated during the 2023 aerial photography project that was contracted by Eagle View. Certified orthomosaics, LiDAR and various LiDAR derivatives (DEM, point cloud, and contours) were created as a result of the project. “Layer” field will include values to allow users to further filter contour intervals (Please see below). Elevation value for each line are within a string and integer data type field. Caputure Date: March 2023 INDEX: 10 ft major contour lines (multiples of 10; e.g., 600, 610, 620) INTER: 2 ft intermediate contour lines (even multiples not divisible by 10; e.g., 602, 604, 606) MINOR: 1 ft supplemental contour lines (odd elevations; e.g., 611, 613, 615)本折线要素数据集展示了温彻斯特市（City of Winchester）的5英尺等高距地形等高线，该数据集为1英尺等高距原始数据的子集。本次等高线数据源自鹰景（Eagle View）承揽的2023年度航空摄影项目。该项目最终产出经认证的正射影像镶嵌图（orthomosaics）、激光雷达（LiDAR）数据及其各类衍生产品，涵盖数字高程模型（DEM）、点云（point cloud）与地形等高线。“图层（"Layer"）”字段将包含分类值，以供用户进一步筛选不同等高距的等高线（详见下文）。各线要素的高程值存储于兼具字符串与整数数据类型的字段内。采集日期：2023年3月。主等高线（INDEX）：10英尺主等高线，为10的整数倍高程值，例如600、610、620；中间等高线（INTER）：2英尺辅助等高线，为不能被10整除的偶数高程值，例如602、604、606；补充等高线（MINOR）：1英尺补充等高线，为奇数高程值，例如611、613、615。
