Two Foot Contours

This feature service provides contour line data derived from lidar elevation measurements collected in 2024, representing ground surface topography at a two-foot interval. It is hosted by the DeKalb County GIS Department and offers terrain elevation information for geographic analysis within the county. Two Foot Contours is a layer of contour lines created from 2024 lidar data, representing elevation changes across the landscape. Each line reflects specific elevation values, supporting analysis of terrain, slopes, and landscape features. The data includes attributes such as elevation values, contour indices, and update metadata. The data covers DeKalb County with spatial reference suitable for local planning, environmental assessment, and engineering applications.本要素服务提供基于2024年采集的激光雷达（LiDAR）高程测量数据生成的等高线数据，以2英尺间隔表征地表地形形态。本服务由迪卡尔布县地理信息系统（GIS）部门托管，可为该县内的地理分析提供地形高程信息。“2英尺等高线”是基于2024年激光雷达数据构建的等高线图层，用于表征全域地表的高程变化。每条等高线均对应特定高程值，可支撑地形、坡度及地表景观特征的分析工作。该数据集包含高程值、等高线索引及更新元数据等属性字段。数据集覆盖迪卡尔布县全域，其空间参考系统适配本地规划、环境评估及工程应用等场景。
