Development site that I use to collate and compare data for my bridge height estimates.
The Environment Agency provides tide data in API form that is freely available. I collate this information by timestamp into a single table so that I can easily compare Lowestoft, Gorleston, and Haven Bridge data to create my realtime bridge height estimates.
NB. at the moment, only the Lowestoft data is available in near-real-time. Gorleston can often be a hour behind and Haven Bridge is usually only available for the previous days up to 0430 on the day of the API query.
