Summary

This data release includes a file geodatabase with land cover maps for a 313-kilometer segment along the mainstem Klamath River corridor downstream from Iron Gate Dam, CA. The maps were derived from high-resolution (15cm) imagery and topobathymetric elevation data, collected by NV5 Geospatial (formerly QSI, Inc) and published on Open Topography (https://doi.org/10.5069/G9DN436N). Acquisition dates spanned 06/01/2018 to 06/14/2018. The area of interest was discretized into three zones and land cover maps were generated using geoprocessing tools, implemented in ArcMap 10.8.1, and image classification tools, implemented in Ecognition 10.2. The maps include six land cover classes: 1) trees, 2) shrubs, 3) grass, 4) bare ground, 5) rock [...]

Purpose

Baseline land cover maps were created to show the spatial distribution of major vegetation types (grass, trees and shrubs), rock outcrops, bare ground and water along the mainstem Klamath River corridor from Iron Gate Dam to the estuary prior to dam removal. The intended uses of these data include, but are not limited to, comparison of the distribution and area of land cover types before and after dam removal and characterization of the biological and physical responses to dam removal. Users should be aware of the inherent errors in remote sensing products. Users may create a Level I classification with improved accuracy by combining the bare ground and rock outcrop classes into a single unvegetated class and the trees, shrubs and grass classes into a single vegetated class.
