Water temperatures
收藏资源简介:
The city of Malmö measures water temperatures in the sea at a number of bathing areas. The measurements are made with temperature sensors that are placed close to the surface (optimally at a depth of about 50 cm) some 50 meters from land. The sensors normally report the temperature a number of times per hour and the average value per hour is what is published in this dataset. Incorrect measurement values are uncommon but can occur if sensor operation is disrupted. The resources consist of GeoJSON files (Locations YYYY-MM.geojson) that show the sensors that have been active and their approximate location on a monthly basis. Corresponding measurement values per month are available in CSV files (Water Temperatures YYYY-MM.csv). Measurement value files follow [FIWARE's specification for WaterQualityObserved](https://fiware%2ddatamodels.readthedocs.io/en/stable/Environment/WaterQualityObserved/doc/spec/index.html) . **Attributes Locations** * `id` [sensor identity] * `address` [sensor location (text)] * `geometry` [approximate position of the sensor, type: Polygon, CRS: WGS84] **Attributes Water temperatures** * `type` [always "WaterQualityObserved"] * `id` [sensor identity] * `address` [sensor location (text)] * `dateObserved` [date and time (ISO 8601 format) when the measurement value was reported] * `temperature` [measured temperature in degrees Celsius]
