• Scope: The app is intended to display NOAA real time reporting tide stations in a map rendered by Google maps Javascript API. Once clicked on the map, it should render the last 24 hrs for tide level information retrieved., including current level.

In order to achieve that, a rake process will read all the current tide stations from a txt file ( station_list.txt). This is necessary because at the time the app is being written NOAA does not provide an online service or list that can be retrieved in any other way than 'scraping' the information of a website. I am considering to write an small JSON API to hold this data.

There are three rake tasks:

• rake station_list:delete_station_list Delete all of the stations information from the database

• rake station_list:process_station_list Reads the list of all stations from station_list.txt, and saves a single row in the database with a tide_info array of text containing all of the reporting stations id's:

SELECT "stations".* FROM "stations" ORDER BY "stations"."id" DESC LIMIT 1 => ["9461380", "9461710",...]

• rake station_list:retrieve_all_stations_metadata # Run Process

Reads the list of all stations from station_list.txt, and appends to the record saved by the above process another single row with a JSON field (metadata) that stores all of the stations metadata, eg:

{"station_id"=>"9461380", "station_name"=>"Adak Island", "latitude"=>"51.8633", "longitude"=>"-176.6320"}

This rake task uses the TideParsingService, and prevents inconsistent data if an station in particular is not reporting tide levels. It also parses the parameters 's' and the timestamps for this readings.

• Deployment instructions rake stations_delete:delete_station_list # Delete Station List rake stations_id_list:process_station_list # Station List rake station_list:retrieve_all_stations_metadata # Process metadata

Note from NOAA: These raw data have not been subjected to the National Ocean Service's quality control or quality assurance procedures and do not meet the criteria and standards of official National Ocean Service data.
