Parse data from http://www.ndbc.noaa.gov/ and http://tidesandcurrents.noaa.gov

This project is used to parse data in Buoy Buddy , an iOS app showing wave and tide data.

Buoy data can be loaded from the latest observation url:
http://www.ndbc.noaa.gov/data/latest_obs/latest_obs.txt

And then passed to Buoy.lastestObservation(rawData) to get an object of stations and their current conditions.

Or it can be loaded from:
http://www.ndbc.noaa.gov/data/realtime2/{stationID}.txt

And passed to Buoy.realTime(rawData) to get a single station an its history of conditions.

$3

Tide data can be loaded by using:
http://tidesandcurrents.noaa.gov/api/

And then passed to Tide.parse(rawData)

This returns a tide object, that can be passed to Tide.getCurrent(tideObject, forDate) to return the current tide.

To find the next high or low tide, use Tide.getNextHighOrLow(tideObject, forDate)

For both methods, the second argument is Date object, and the default value is now, if left unspecified.

For parsing published Tide Table data, use Tide.parseTideTable(rawData)

Tide Tables can be found on pages like:
