Data types

AirWare includes a set of basic and composite data types and OBJECTS for which dedicated import, editing, analysis and display functions are provided.

The data types include:

  1. Descriptors are scalar, symbolic, numeric (with associated symbolic range definitions and defaults), or text variables that are managed by the embedded expert system and a dedicated interactive editiong tool.

    Descriptors are used to define the parameters for more complex types such as:

  2. Time Series which in addition to their numeric value have an associated explicit time stamp;
  3. Matrices, which in addition to the numeric value of each cell have a location (georeference) and geometry, including possible vertical layering, and again may have explicit time stamps.
  4. GIS data (georeferenced) including points, lines, topological networks, polygons, and rasters as individual map overlays and composite maps.
  5. Hypertext including imagery, used to descrobe OBJECTS (see below);
These basic data types are grouped into various compount structures or OBJECTS: OBJECTS are complex composites of basic and derived datatypes; examples for OBJECT classes in AirWare include:
  • Monitoring Stations that contain time series data;
  • Point Sources that hold emission data;
  • Indudstraial plants, that combine several point and possibly area sources;
  • Area sourcxes of emissions;
  • Line sources representing road segments;
  • Road networks that provide a topological framework for line sources;
  • Matrix objects, that manage the 2D data sets for the distributed models;
  • Model domains that define areas of interest for simultion;
  • Meteorological scenarios, tha hold consistent and complete data sets for the simulation models, bound to a model domain and derived from monitoring stations.
  • Emission scenarios, dynamically derived for a model domain;
  • Model scenarios, that compile the above sub-scenarios and can trigger model and display and analyse their results;
