Short-Term Network (STN)
What's with the name?
Short-Term Network (STN)
Why is it needed?
...has evolved into a suite of products
The Short-Term Network Universe
STNWeb (Internal)
STN Data Portal (Public)

for power users and developers
Flood Event Viewer
Brief History
Hurricane Irene Mapper (2011)
Flood Event Viewer 1.0
born ~2012
originally 'STN Public'
Flood Event Viewer 2.0
developed 2016, released October 2016
Event-Centrism in FEV
all data gets associated with an event
Water Science Centers and the press want event-focused map
Real-time Data
Real-time Stream Gage
Rapid Deployment Gage
Real-time Stream Gage layer
Rapid deployment gage layer
metadata in STN - time series data in NWIS
Sensor layers
- Storm tide, Barometric pressure, Meteorological, Wave height
- non-transmitting - must be deployed and retrieved
Sensor layers overlap
Overlapping Marker Spiderfier for Leaflet (github/jawj)
- metadata
- raw data files
- photos
High-water Mark layer
observed & surveyed
historic HWM effort underway
Interpreted Data
Peak Summary
Peak Summary layer
calculated after the event
interpreted data - based on multiple input
Getting Data
Technology Stack
service-oriented architecture
