1. Key Activities.
The DWG will focus on the following activities:
1. Reviewing the current LandXML schema and determining how best to continue to support the existing users and engage with them.
2. Assessing the current industry support for the LandXML schema and whether multiple, incompatible versions of the schema have evolved.
3. Investigating how to best incorporate LandXML into the OGC standards framework, including identifying places where there may be common elements in existing standards such as CityGML.
4. Investigating the possibility of moving the LandXML schema into LandGML.

COBWEB will leverage the UNESCO World Network of Biosphere Reserves (WNBR). Concentrating initially on the Welsh Dyfi Biosphere Reserve, we will develop a citizens’ observatory framework, and then validate the work within the context of the UK National Spatial Data Infrastructure (SDI) and internationally, within the WNBR; specifically, within Greek and German Reserves.
OGC Testbed 10 (OWS-10) brings new capabilities

This groundwater interoperability experiment (GW2IE) will develop and test the GroundWater Markup Language 2, by harmonizing and advancing existing modeling initiatives such as: GWML1, relevant EU-INSPIRE models (Geology-hydrogeology, Environmental monitoring facilities), GeoSciML, and others. It will produce an engineering report in preparation for movement to an OGC data specification subsequent to the GW2IE.
OGC’s Climatology-Hydrology Information Sharing Pilot, Phase 1 (CHISP-1) project was conducted as a Pilot initiative, a collaborative effort that applies technology elements from the OGC Technical Baseline and other (non-OGC) technologies to address Sponsor requirements and scenarios.
What is it? An inter-disciplinary, inter-agency and international virtual observatory system for water resources information from observations and forecasts in the U.S. and Canada, building on current networks and capabilities, designed to support these functions:
- Hydrologic modeling for historical and current stream flow and groundwater conditions. Requires the integration of trans-boundary stream flow and groundwater well data, as well as national river networks (US NHD and Canada NHN) from multiple agencies. Emphasis on time series data and real-time flood monitoring.
- Modeling and assessment of nutrient load into the lakes. Requires accessing water-quality data from multiple agencies and integrating with stream flow information for calculating loads. Emphasis on discrete sampled water quality observations, linking those to specific NHD stream reaches and catchments, and additional metadata for sampled data.
- Collection and preservation of provenance, uncertainty measures, and other metadata throughout processing workflows.
Key objectives of these use cases are:
- To link observations data to the stream network, enabling queries of conditions upstream from a given location to return all relevant gages and well locations. This is currently not practical with the data sources available.
- To bridge differences in semantics across information models and processes used by the various data producers, to improve the hydrologic and water quality modeling capabilities.
Why do it now? Improved capabilities for sharing, accessing, and integrating hydrologic and climatic data have been identified as a critical need for some time. We are at a point in time at which an opportunity exists to make large steps forward by leveraging existing resources – including data portals, standards, technologies, activities, and expertise – to develop an initial operational capability for the system described above.
- Leverage a large body of existing data holdings and related activities of multiple agencies in the US and Canada.
- Influence data and metadata standards used internationally for web-based information sharing, through multiple agency cooperation and OGC standards setting process.
- Reduction of procurement risk through partnership-based development of an initial operating capability verses ~10x the cost for building a fully operational system using a traditional “waterfall approach”.
- Identification and clarification of what is possible, and of the key technical and non-technical barriers to continued progress in sharing and integrating hydrologic and climatic information.
- Promote understanding and strengthen ties within the hydro-climatic community. This is anticipated to be the first phase of a multi-phase project, with future work on forecasting the hydrologic consequences of extreme weather events, and enabling more sophisticated water quality modeling.

OGC has identified the need for standardized interfaces for sensors in the Web of Things (WoT). The Sensor Web interface for IoT SWG aims to develop such a standard based on existing WoT portals with consideration of the existing OGC Sensor Web Enablement (SWE) standards.
