Data documentation: GCAM USA state-glu spatial boundaries with mapping/aggregation file Summary: These data products present a vector file which represents the intersections of state boundaries for USA with GCAM basin boundaries within USA and a mapping file that can be used to map basin level data to states within the USA region (based on area) map state level data to basins within the USA region (based on area) The vector file presents metadata to the user regarding the state name, state id, glu name and glu id along with a unique key for each polygon. These spatial boundaries can be reproduced/updated by updating the inputs and making use of the methodology described below. CONTENTS: gcamusa_state_glu_wgs84 folder contains the following, shape_file folder contains the following, gcamusa_state_glu_wgs84.shp column names in outputs: key: Unique identifier for feature state_id: Unique identifier for state (state geo id) glu_id: Unique identifier for basin (basin number) state_nm: State name glu_nm: Basin name mapping_file folder contains the following, state_glu_mapping_WGS84.csv column names in outputs: state_id: Unique identifier for state (state geo id) glu_id: Unique identifier for basin (basin number) state_nm: State name glu_nm: Basin name state_area: Geometric area calculated for each state glu_area: Geometric area calculated for basin/glu intersection_area: Geometric area calculated for each basin-glu intersection state_proportion: Share of glu value in a state glu_proportion: Share of state value in a glu input_files folder contains the following, glu_boundaries_moirai_combined_3p1_0p5arcmin : A shape file containing boundaries for the GCAM glus. source: https://zenodo.org/record/4014308#.X6nkQ2hKhaR tl_2019_us_state.shp : A shape file containing boundaries for USA states. Source: https://www.census.gov/geographies/mapping-files/time-series/geo/tiger-line-file.html Methodology and reproducibility: The vector and mapping files were generated using the function located here- https://github.com/JGCRI/rgis/pull/7/commits/32ccb8cf8a30a66a84044da317b9041f492777be In order to reproduce or update the outputs the user would have to follow the following steps: Clone the rgis package from GitHub - https://github.com/JGCRI/rgis Use the get_intersection_fractions() function. Set the shpfile_1 parameter to the path to the latest state boundaries and set shpfile_2 parameter to the path to the glu boundaries shape file. Set the out_csv parameter to the desired mapping file name and set the out_shape_file parameter name to the desired vector output name.
