Fetches ATTAINS features (state- or tribe- or other entity- submitted points, lines, and polygons representing their assessment units; and the EPA snapshot of the associated NHDPlus HR catchments that the state- or tribe- or other entity- submitted features fall within) within a bounding box produced from a set of TADA spatial features.
Arguments
- .data
A dataframe developed using
TADA_DataRetrieval()orTADA_MakeSpatial().- catchments_only
Whether to return just the summarized ATTAINS catchment features, or both the catchments and raw ATTAINS features. TRUE or FALSE.
- org_id
ATTAINS organization identifier(s) as a character string. If populated, Assessment Units will only be fetched from the specified organization(s). A list of organization identifiers can be found by downloading the ATTAINS Domains Excel file: https://www.epa.gov/system/files/other-files/2025-02/domains_2025-02-25.xlsx. Organization identifiers are listed in the "OrgName" tab. The "code" column contains the organization identifiers that should be used for this param. When org_id = "all", Assessment Units from all organizations will be considered. The default is "all".
Value
Spatial features (ATTAINS_catchments, ATTAINS_points, ATTAINS_lines, and ATTAINS_polygons) that are within the spatial bounding box of water quality observations.
