CityGML

CityGML is an open data model and XML-based format for the storage and exchange of virtual 3D city models. It is an application schema for the Geography Markup Language version 3.1.1 (GML3), the extendible international standard for spatial data exchange issued by the Open Geospatial Consortium (OGC) and the ISO TC211. The aim of the development of CityGML is to reach a common definition of the basic entities, attributes, and relations of a 3D city model. This is especially important with respect to the cost-effective sustainable maintenance of 3D city models, allowing the reuse of the same...

Civil Works Technology Insertion, Phase 1

Technology Insertion Project. The CTI Project, sponsored by the US Army Corps of Engineers, Engineer Research and Development Center (ERDC), integrated multiple map servers, including nodes at the Corps' Mississippi Valley Division and the New Orleans District Office. Insertion Projects focus on expanding an organization’s interoperability capacity by laying the groundwork for open implementations.

Climate Challenge - Integration Plugfest - 2009

Climate Challenge Integration Plugfest (CCIP) 

"Ensuring that high-quality climate data records are collected, retained and made accessible for use by current and future generations of scientists and decision-makers is a key objective of this Plan. As a result, investment in the data management and analysis components of the system is as important as the acquisition of the data." -- Implementation Plan for the Global Observing System for Climate in Support of the UNFCC, 2004

Climate-Hydrologic Information Sharing Pilot Sponsors

 
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:

  1. 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.
  2. 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.  
 
Expected Benefits

  • 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.
