maudyklos.lt — bathing water quality in in the EU, Latvia and Estonia on one map
An open data project: the Hygiene Institute’s bathing water tests, the European Environment Agency’s quality classes and the Lithuanian Hydrometeorological Service’s temperature data are combined into one website. Each of the 446 locations has its own page with test history, a map location and the nearest other bathing areas, and the data updates automatically.
Challenges
- Hygiene Institute results are published as tables, without location coordinates
- For Latvia and Estonia only the annual EU class is published, not individual samples
- Data must update automatically, without manual work
- The website must run quickly in a shared hosting environment
Solutions
- A map with 446 bathing areas and recreation areas in in the EU, Latvia and Estonia, with filters by country and county
- Each location page: season test history, EU quality classes 2016–2025, nearest other locations
- Air and water temperature from the Lithuanian Hydrometeorological Service stations, updated every hour
- Overviews by county and municipality, a winter section with cold-weather data and safe behaviour on ice information
- A widget for municipality and tourism centre websites, e-mail notifications about changes in test results
- Automatic data updates, open data in JSON and CSV formats, LiteSpeed cache
