- get direction of markers
data
stations are viewable here: https://tidesandcurrents.noaa.gov/map/index.html white stations are subordinate & do not return current prediction data. Only the purple ones return data.
- Positive speed is flood
- Negative speed is ebb
Need a backend that can be hit with
- lat/long boundary
- time
Returns
- All Stations inside boundary
- coordinates
- mean ebb/flow directions
- current speed
Later we'll probably want it to return multiple speeds
