Title: an Object Oriented Shared Data Model for Gis and Distributed Hydrologic Models
Distributed physical models for the space-time distribution of water, energy, vegetation, and mass flow require new strategies for data representation, model domain decomposition, a-priori parameterization, and visualization. The Geographic Information System (GIS) has been traditionally used to accomplish these data management functionalities in hydrologic applications. However, the interactio...

متن کاملDO-GIS - a distributed and object oriented GIS
This paper reports “first cut” of the design of a distributed and object oriented geographic information system, DO-GIS, under development at I.I.T. Delhi. The paper deals with data model, architecture, query processing and data management in a GIS. Considering that geographical data includes information about spatial reference frame, topological connections and requires maintenance of physical...
متن کاملAn Object Model for Shared Data
The classical object model supports private data within objects and clean interfaces among objects. and by defmition does not permit sharing of data among arbitrary objects. This is a problem for certain real-world applications. where the same data logically belongs 10 multiple objects and may be distributed over multiple nodes on the networX. Rather than give up the advantages of encapsulated ...
متن کاملResearch on Object-Oriented Geographical Data Model in GIS
Nowadays, there are many attempts to establish object-oriented GIS in some software However, they are not accordant to object-oriented concept whole and systematically in the whole course from the process of cognizing and abstracting geographical space to the process of defining and describing GIS data model then to the process of analyzing and designing GIS. Especially, the research on common ...
