Research on Object-Oriented Geographical Data Model in GIS
نویسنده
چکیده
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 object-oriented geographical data model is infrequent. In light of this case, based on geographic spatial cognition to the real world, this paper puts forward a common Object-oriented Geographic Data Model (OGDM) by using object-oriented methods and provides a model for establishing the implemental GIS.

Implementation of Object - oriented GIS Data Model with Topological Relations between Spatial Objects
Traditional GIS (Geographical Information System) data models are focused on the description of the data organizational structure and constraints from single aspect, which are the absence or little relevance of the hierarchy and connotation of data objects. These data models do not match the natural concept of humans about geographical spatial data and also failed to fully consider the spatia...

An important issue in implementation of a GIS system is preparation of data to be entered in GIS. To produce spatial data for GIS using photogrammetric techniques, conventional method is to apply photogrammetric and GIS systems individually (off-line procedure). This approach is costly, time consuming and somehow unreliable due to the fact that 3D photogrammetric model is not available at the ...
متن کاملResearch Article: An object model with parametric polymorphism for dynamic segmentation
Dynamic segmentation is commonly viewed as one of the most effective aspects of GIS for transportation applications. To date, much of this effort has focused on relational data models, with object data models receiving far less attention. This paper presents an object model that provides a natural representation of dynamically segmented features by extending the Object Database Management Group...
متن کاملConstruction of an Integrated Object Oriented System for Temporal GIS
The development of temporal GIS systems capable of dealing with the evolution of geographical objects is still a challenging task. Although many successful GIS systems have been implemented, comparatively little has been done on how to determine and analyse the patterns of continuous changes of geographical objects. The aim of this paper is to construct a GIS system using an object-oriented mod...
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...
