LiDAR_Drainage_Paths

Purpose: To provide a detailed spatial representation of drainage paths derived from LiDAR data within Wood County. This dataset supports hydrological analysis, resource management, and environmental planning. Supplemental Information: This dataset was created using high-resolution LiDAR data to identify and map drainage paths, ensuring accuracy in representing hydrological flow patterns and their attributes. Keywords: LiDAR, Drainage Paths, Hydrology, Environmental Planning, Resource Management, Wood County Lineage: Source(s): Derived from high-resolution LiDAR data collected for Wood County. Positional Accuracy: Consistent with the original LiDAR data, ensuring a high degree of spatial accuracy for hydrological modeling and analysis. Attribute Accuracy: Attributes have been verified for consistency with the LiDAR-derived flow accumulation and drainage path modeling. Logical Consistency: The dataset is logically consistent, with continuous drainage lines validated for hydrological network integrity. Type of Data: Vector (Polyline) Composition: The dataset consists of polyline features representing drainage paths. Attributes may include flow direction, stream order, and accumulation values.
