(updated since FEWS release 2008.03, build 20300 and higher)

Within FEWS, a variety of location types is used to hold all model input and outputs:

  • point locations, holding time series of scalars
  • branch locations, holding a longitudinal profile timeseries, i.e. a time series of a river stretch
  • grids, holding a time series on a model grid (or a sparse grid i.e. a cloud of points)
  • polygons, holding a time series on polygons

LocationSets are used to cluster locations into groups which are processed or displayed in one go.

All geographic properties of branch-locations are held in the Branches.xml file
All geographic properties of gris are defined in the Grids.xml file
All geographic properties of polygons are defined in the Polygons.xml file, which typically refers to an ESRI shape file to hold the shapes.
Basically, all geographic properties of point locations are held in in a shape/dbf-file, where the DBF file may hold specific attributes to create subsets or hold IdMap references. F

However, since FEWS software relates all its time series data to locations, as defined in the Locations.xml, one should take care that all branches, grids and polygons have a locationId in the Locations.xml file to act a a placeholder. In addition, the locations.xml holds the placeholders for the 'new wells'.

LocationSets can refer to a shp/DBF-file. Query mechanisms on field content can be used to create subsets.

Example:

  • No labels
