WaterML 2.0 is a candidate OGC encoding standard for the representation of in-situ hydrological observations data. WaterML 2.0 is implemented as an application schema of the Geography Markup Language (GML) version 3.2.1 and makes use of the OGC Observations and Measurements (O&M) standard and the O&M eXtensible Markup Language (OMXML) GML Application Schema. OGC WaterML 2.0 will support encoding of hydrological and hydrogeological observation data in a variety of exchange scenarios.
Example areas of usage are: exchange of data for operational monitoring and forecasting programs; supporting operation of infrastructure (e.g. dams, supply systems); exchange of observational and forecast data for surface water and groundwater; release of data for public dissemination; enhancing disaster management through data exchange; and exchange in support of national reporting. WaterML 2.0 was developed by a group of hydrology and water professionals. It harmonises concepts from a number of existing standards in use.
