Map management: embedded GIS

WaterWare manages a range of spatial data sets and maps, both as input data for distributed models and as geographical background for the display of spatial objects and model results.

Several distinct groups of data/functions are supported:

  • live Google maps (with arbitrary zooming and panning, swicy between different maps styles) as background, for geographical orientation;
  • mapset and maps interactively composed from available overlays, combining rasters (such as satellite imagery) and line formats using UTM projection;
  • matrix data, primarily as sptaial model input and poutput format;
  • export formats such as netcdf and support for a WebMapServer.

MapServer embedded GIS

WaterWare uses an embedded MapServer that manages a MapSet (a collection of at least in part overlapping overlays with the same projection) together with a

  • MapComposer configuration tool to combine several individual topical overlays, over an optional raster background map.
  • MapCatalog overview and map selection to associate named maps with OBJECTS and OBJECT CLASSES including model domains,
  • MapImport and overlay description tool,
to provide geographical background and orintation/reference for its data (OBJECTS and spatial model inputs and results.

In addition, a range of georeferenced data that can be viewed as topical maps are used as model inputs.

For the user, the MapServer is transparently embedd with all georeferenced OBJECT CLASSES, model scenarios and their underlying domains, model inputs data sets, and model results.

Within a given application, a MapSet of available overlays is defined. A MapImport function is associated with the display and definition od the raw map layers or overlays, accessible from the central MapComposer.

GIS formats supported for import include

  • ArcView Shape files (topical maps, one topic at a time)
  • Raster formats (TIFF).

User interaction

GIS related operations the user can perform include:

  1. Selection of the map style: the individual class selectors offer a configuration choice between map_style = [MapServer|Google]; for the class selector (navigator) page, the configuration patameter: navigator_map_style can be used.
  2. Map Composition from the set of individual topical overlays, including the definition of optional ViewPorts for individual named maps;
  3. Map Import, interactive import of maps (raster format) or (single topic) topical map overlays from client PCs (please note that composite maps with several topics can be constructed with the Map Composition tool)
  4. Map Catalog Browsing and selection of maps as the background for individual OBJECTS and OBJECT CLASSES including model domains;
  5. Background Map Selection: interactive selection of background maps for
    1. Model domains
    2. all georeferenced OBJECT classes
    3. all georeferenced OBJECTS (instances).
  6. Object Geometry: Import for Area Sources and Receptor Area polygon boundaries
    (single feature of a single-topic ArcView Shape file); alternatively, the geometry of an object can be digitized interactively over a Google map
  7. Object Geometry: Import for Line Sources polylines or line segments (single topic ArcView Shape file).
  8. Object Location, definition of the location of point sources (or object with a reference point) directly on the map (Google);
