May 18, 2016 -- The Open Geospatial Consortium (OGC®) is requesting comments on the WaterML 2: Part 4 - GroundWaterML 2 (GWML2) candidate standard.
GWML2 provides an encoding for data involved in the study and use of groundwater. The candidate standard includes conceptual and logical models as well as an XML-based encoding schema. GWML2 is part of the larger WaterML2.0 suite of standards coordinated in an initiative within the joint World Meteorological Organization (WMO) / OGC Hydrology Domain Working Group to address standards development and interoperability of hydrological information systems at an international level.
The GWML2 standard is motivated by 5 usage scenarios that focus on commercial uses (drilling water wells), policy uses (managing aquifers), environmental uses (protecting ecosystems), scientific uses (groundwater modeling), and technical uses (data interoperability). GWML2 consists of six modules including: (1) core entities (aquifers and groundwater bodies), (2) groundwater constituents (biologic, chemical, and material), (3) groundwater flow, (4) water wells and groundwater monitoring, (5) water well construction, and (6) aquifer testing.
Two OGC Interoperability Experiments were performed to test and enhance GroundWaterML capabilities, which resulted in the first version of GWML2. Further content was developed in conjunction with contributors from North America,Europe, Australia and New Zealand.
The document is available for public comment at this link. Comments are open until 17 June, 2016.
About the OGC
The OGC is an international consortium of more than 515 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC standards support interoperable solutions that "geo-enable" the Web, wireless and location based services, and mainstream IT. OGC standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled. Visit the OGC website at
