“ChesBay 24k – LU": Land Use/Land Cover Related Data Summaries for the Chesapeake Bay Watershed Within NHD Plus HR catchments

These tabular data are summaries of land use/land cover related variables within catchments of the Chesapeake Bay watershed using the Xstrm methodology at 1:24,000 scale. Variables being counted as land use/land cover related contain all land use and land cover data including datasets that are split off or combined from those data (eg. agriculture or impervious classes only datasets). Outputs consist of tabular comma-separated values files (CSVs) for both the local catchment and network summaries linked to the National Hydrography Dataset Plus High-Resolution (NHDPlus HR) framework by NHDPlus ID. Local catchments are defined as the single catchment the data is summarized within. Network accumulation summaries were...

Urban and developed areas indicated by classification of Landsat 2018 multispectral imagery

Polygons indicate the extent of urban (gridcode 5) and developed (gridcode 6) land cover in the greater Kabul area. Polygons were created from classification of Landsat 8 Operational Land Imagery (OLI) 30m resolution multispectral satellite imagery acquired on June 13, 2018.
