Climatology-Hydrology Information Sharing Pilot, Phase 1
For more information please contact email@example.com
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.
The objective of the CHISP-1 initiative was to develop an inter-disciplinary, inter-agency and international virtual observatory system for water resources information from observations in the U.S. and Canada, building on current networks and capabilities.
The Pilot was a collaborative effort that applied technology elements from the OGC Technical Baseline and other (non-OGC) technologies to Sponsor scenarios. The Pilot was conducted to “stress test” a set of OGC standards based on real-world application and experience. The majority of work for CHISP-1 was conducted from November 2012 through April 2013.
The CHISP-1 Pilot Summary Engineering Report (ER) is available for public download at the link below. It provides an overview of the project with information about the project objectives, its sponsors, participants and schedule:
Technical details about the technology, services and use cases used to demonstrate the results achieved can be learned from the project’s technical Engineering Report available below.
Demonstration and Presentations
A live demonstration and presentation was conducted as a public webinar, hosted and broadcast by Directions Media, on 16 April 2013. Recording of the webinar is available for review by the public here:
A second CHISP-1 Demonstration was also conducted during the Hydrology DWG meeting on 19 June 2013 in Quebec City.
Slides presented to accompany the two demonstrations are available here:

The CHISP-1 Engineering Report (ER) (OGC 13-053) has been prepared to record details of the technical architecture, description of the system components and functions, and lessons-learned along with recommendations for potential future work items. The ER is available for public download here:
The CHISP-1 project was sponsored by the following organizations:
- Environment Canada
- Natural Resources Canada (NRCan)
- NRCan Groundwater Science Program
- US Geological Service (USGS)
- Environmental Protection Agency (EPA)
In addition, the following sponsors and organizations provided data and web services for the project:
- American Geosciences Institute
- Environment Canada / Natural Resources Canada
The following OGC member organizations were participants in this project. Additionally, there were 7 other organizations that were observers of CHISP-1.
- Explorus Data Solutions
- RPS ASA (Applied Science Associates)
- GIS Research Center, Feng Chia University (GIS.FCU)
- For the first time, provided a capability for an EM Analyst (or anyone) to view trans-boundary upstream hydrometric (and groundwater) data via the web in near real-time.
- Developed a capability to monitor all available upstream stations independent of location or jurisdiction to generate an alert in case of flood and/or drought.
- Developed and demonstrated use of the GetDataAvailability (GDA) operation for SOS v2 for retrieval of time-series WaterML2 encoded stream flow data.
- Demonstrated interoperability through integration of SOS, WPS, WNS, and CSW services along with the OASIS CAP standard to provide near real-time threshold monitoring and notification to support alert mechanisms across international boundary and jurisdictions.
- Implemented a single SOS service to monitor cross-border international water quality sample data.
- Demonstrated integration and interoperability of international data services using the SOS and WaterML2 for stream flow and water quality data in order to execute a web-based nutrient load model.
- Implemented a system to identify upstream water level and flow gauges regardless of relation to US/CAN border.
- Implemented a Harvester capability to automatically retrieve and store time-series WaterML2 data for streamflow and water level; and to identify if an identified threshold value had been reached on a near real-time basis.
Pilot Use Cases and Functions
The CHISP-1 Initiative was designed to support these Use Case functions:
Hydrologic monitoring and alerting for historical and current stream flow and groundwater conditions.
- Integrate trans-boundary stream flow and groundwater well data, as well as national river networks (US NHD+ and Canada NHN) from multiple agencies with emphasis on time series data encoded as WaterML2 and real-time flood monitoring.
Calculation and assessment of stream flow nutrient loading into the Great Lakes.
- Access water-quality data from multiple agencies and integrate with stream flow information for calculating nutrient loads. Emphasis was on discrete sampled water quality observations, linking those to specific US and Canadian stream reaches and catchments, and additional metadata for sampled data.

OGC Pilots are a collaborative effort that applies the OGC Technical Baseline and other (non-OGC) technologies to Sponsor scenarios. In practice, a Pilot is where an OpenGIS specification – or set of OpenGIS specifications – can be “stress tested” and perfected based on real-world application and experience. While some research may be done during a pilot in terms of refining, documenting, and distributing specifications and in terms of developing prototypical software that exercises the refined specification, this research is directed at improving existing specifications rather than in creating new specifications.
