An object-based spatial database is a spatial database that stores the location as objects. The object-based spatial model treats the world as surface littered with recognizable objects (e.g. cities, rivers), which exist independent of their locations. Objects can be simple as polygons and lines, or be more complex to represent cities. While field-based data model see the world as continuous surface over which features (e.g. elevation) varies.

  • An object-based spatial database is a spatial database that stores the location as objects. The object-based spatial model treats the world as surface littered with recognizable objects (e.g. cities, rivers), which exist independent of their locations. Objects can be simple as polygons and lines, or be more complex to represent cities. While field-based data model see the world as continuous surface over which features (e.g. elevation) varies. Using object-based spatial database, it is easier to store more attributes with the objects such as direction, speed, etc. , using these attributes can make it easier to answer queries like "find all tanks whose speed is 10 km and oriented to north". Or "find all enemies tanks in certain region". Storing attributes with objects can provide better result presentation. and improved manipulation capabilities in more efficient way. In field-based data model, this information is usually stored at different layers and it is harder to extract different information from various layers. This data model can be applied above the ER as in GERM model and GISER. S. Shekhar introduces direction as a spatial object and present a solution to object-direction-based queries. Describe the architectures of various object-relational spatial data models, including spatial extensions of DBMS, proprietary object-based data models from GIS vendors, and open-source and standards-based efforts
  • Un objet spatial est un type de données particulier pour les bases de données relationnelles. Ces objets peuvent être simples comme un point, une ligne, un polygone ou bien plus complexes; ils représentent des données géographiques.
