Incorporating hydrologic semantic information for interoperable GIS with hydrologic model

Abstract

Component-based approach has been identified as an efficient way to integrate GIS and hydrologic models. Current existing specifications such as OpenGIS or IOS/TC 211 provide a vessel to achieve this goal. However, there is a gap between what is provided in these specifications and what is needed for GIS-hydrologic model integration. Existing specifications provide general semantics for spatial domain, while integration of GIS and hydrologic models requires encoding more specialized spatial domain used in hydrologic models. In this paper, we propose developing an information community-specific abstract data model that would be based on the OpenGIS abstract specification with the intent of achieving interoperability between GIS applications and hydrologic simulation models. Mapping results are presented.
