watershed_tools

master development ground for general watershed tools (delineation, viz, remote sensing, etc...)

2_batch_summary_contUS.R

  • Includes functions for:
    1. acquiring NHDPlusV2 COMIDs based on lat/long
    2. acquiring NHDPlusV2 VPU IDs based on lat/long
    3. using COMID and VPU to acquire NHDPlusV2 data for your sites
    4. using COMID to acquire StreamCat data for your sites
    5. determining the position of a site along its NHD reach and calculating reach proportion, so that you can adjust linear and areal summary data accordingly
  • These only work in the continental USA.
  • Broader data acquisition (MODIS, NEON, etc.) using watershed boundary shapefiles is coming soon.
  • A global equivalent of these tools is also hopefully coming soon.
  • These functions will eventually be packaged.
