Object Data Base

AirWare includes a general purpose OBJECT DATA BASE that manages georeferenced or generic objects. A multi-attribute selector/navigator provides access to classes and instances, and support a range of filtering and sorting operations.

The objects in AirWare are grouped by CLASS. The list of CLASSES is open and can be configured and extended easily.

OBJECT CLASSES supported vary with the application (a typical set for AIrWare is given below). for a complete set, please refer to: OBJECT TEMPLATES.

  • Monitoring stations
  • Time series data sets;
  • Meteorological scenarios (complete, consistent and synchronized data sets)
  • Emission sources, including
    • point sources (boilers/stacks),
    • area sources,
    • line sources (road segments)
  • Emission patterns
  • Fleet composistions
  • Road networks (topological structure as used in transportation models)
  • Industrial plants or installations (containers for point sources, possibly also parallel area sources for fugitive emissions);
  • Model domains (geographically defined);
  • Overlays and Maps (set of overlays in specific stacking order).
  • Matrices (model input related)

Each of these CLASSES may have any number of elements.

Each class has a set of specific attributes, organized in a set of data structures and associated METHODS for instantiation and display. Selecting an OBJECT from the listing within a CLASS starts a display and editing page for the object.

Data structures include

  1. HEADER with name and id (mandatory), location, and meta-data information, common to ALL object classes; The LOCATION of the object is used, together with a specifications of EXTENT (a radius around it) to define a VIEPORT to generate a MAP of the surrounding of the object with the object diaplyed as a SYMBOL in the center of the MAP.

  2. ATTRIBUTE SET that is class specific; they may include:
    • Hypertext including imagery for a detailed description;
    • Tables of Descriptors, using XPS library functions for editing and inference;
    • Time series of scalars, vectors, or lists;
    • Matrices
    • References to related objects (children or sibblings);
