Dashboards, alerting, and integration product that unifies Hohonu, NOAA, and USGS gauge data on one map.
Hohonu Act presents Hohonu, NOAA, and USGS gauge readings together on a single map with per-site advisory and warning thresholds. When thresholds are crossed it sends text and staff alerts, and a public self-serve dashboard gives residents live water level views.
Data flows out through an API, GeoJSON, CSV exports, and embeddable widgets into ArcGIS, emergency operations center dashboards, National Weather Service workflows, and road-closure tools. Agency deployments include threshold alerts with Waze road-closure sharing in Charleston, South Carolina and an ArcGIS feed serving Pinellas County, Florida.
