+Temporal orthophoto rasters additionally require a governed product key, WMS
+layer, observation label, `observed_at`, optional `valid_from`/`valid_to`,
+temporal granularity, request/spatial hash, attribution and a limitation that
+states whether the product is annual, multi-year or merely most recent.
+
+### Hydrological station observations
+
+Waterinfo observations are persisted as EPSG:4326 Point features, one station
+and one observation year per immutable Dataset. Required properties are the
+station/timeseries identity, measurement type, numeric annual value, reported
+unit, observation year, provider/owner and attribution. Different station
+series may not be merged into one area-wide value. Point water level and
+discharge may not be converted to water volume without governed compatible
+depth/profile data.
