Antecedent Precipitation Tool (APT), fully automated.

Get the APT data and PDF you need, automatically. Ecobot Manager runs the USACE Antecedent Precipitation Tool using the dates and locations of your project's points, or a centroid on a date you specify. Same code USACE publishes on GitHub, so the output is what you'd produce running it locally.

  • Automatic runs from your project's point dates and locations, no manual setup
  • Or pick a centroid and date when that's what the determination calls for
  • Standard APT PDF, ready to attach to a JD or 404 package
  • Raw JSON output for downstream internal workflows
  • Powered by the official USACE APT code from GitHub
