1. A method of building and maintaining an object-oriented database from a vector product format (VPF) database, comprising:

  • instantiating objects of the object-oriented database, using the VPF database;

    initializing spatial and non-spatial feature data of the object-oriented database, thereby creating a feature level having, non-spatial data which provides characteristic properties of each feature;

    spatial data, including primitive data and topological information, which provides spatial relationships between a feature object and other feature objects within a specified coverage; and

    wherein related non-spatial and spatial data are directly accessible from the feature object;

    spatially indexing data among objects across hierarchical levels of the object-oriented database; and

    updating spatial and non-spatial data.
