GovBot Tides & Terrain
ChatGPT pluginTide and terrain briefs
Prepare a coastal water-level history brief, a dated astronomical tide table or public-point terrain and watershed context. Six read-only tools retrieve public NOAA CO-OPS station records, observations, predictions and datums, plus USGS elevation and watershed records. Three skills preserve station capabilities, datum and epoch, units, clock conventions, quality flags, source dates and returned coverage. Astronomical tides are not weather or flooding forecasts; modeled ground is not a survey. Missing records do not establish zero values or safety. No property flood-zone, elevation-certificate, navigation-safety, engineering or insurance determinations, address lookup or arbitrary station-datum transfer to terrain. No sign-in required. Not an official product of or endorsed by any government agency or OpenAI.

Example prompts
- “Prepare a Sewells Point water-level history brief for August 1–2, 2026, preserving datum, units and quality.”
- “Explain Sewells Point high and low tide predictions for October 27, 2026, with the station local clock.”
- “Explain elevation and HUC8/10/12 context at the public Norfolk city-center point 36.8508, -76.2859.”
Skills
terrain-watershed-brief
Prepare a public-point terrain and watershed context brief using USGS elevation and Watershed Boundary Dataset records. Use for modeled ground elevation, nested HUC context and source limitations, not surveys, elevation certificates, parcel flood zones or station-datum conversions.
tide-prediction-brief
Prepare a NOAA astronomical tide prediction brief for a station and bounded dates, or compare its predictions with matching observations. Use when users need tide times, predicted levels and the meaning of the selected datum, units and local clock, with station capability and coverage limits.
water-level-history-brief
Prepare a dated NOAA coastal water-level observation brief for a named station or public research point, including station suitability, reported levels, quality flags, datum and time coverage. Use for historical measured water levels, not astronomical tide predictions or property flood determinations.
