Command center for municipal demands
After the module has been selected,
a form "selection criteria" will open. This form looks similar for all
modules, and functions as a "command center" to initiate the following
- Spatial selection of demand centers (uses a separate form)
Note: Inverse Selection will only be applicable after the demand centers of the first data selection have been processed.
- Entry of reference year (absolutely necessary, if this field is empty you can not proceed entering demand-related data)
Note: You are prevented from entering years for which
there either no population figures (i.e. before 1994 or currently after
1999) or no billing data stored.
- Optional reduction of the results from spatial selection with the following query criteria:
type of settlement (see also table SETT_TYPES for full reference),
population number (in the reference year) and
absolute amount of water use (in the reference year) .
This helps to distinguish different types of demand centers, as they may have a different development.
- Alternatively, you can load the demand centers and the reference year from a previous session .
- Export data from the reference year to Excel .
- Export data from reference year to STP .
The screenshot below shows the form after spatial selection and entry of a reference year. Like most other forms, also this form possesses a number of controls. Move
with the cursor over the image. If the cursor changes from arrow to a
hand, you can click to find detailed explanation about the controls.
The listfield shows the selected demand centers with the following attributes:
- SETT_ID: Settlement ID
- TYPE: code for the type of settlement acc. table SETT_TYPES
- P_CEN: Population in the census year (usually 1994)
- P_REF: Population in the reference year as calculated from DOS growth figures and stored in table STP_POPULATION.
This is the figure on which both the per-capita consumption estimates
of the reference year and the development of future population will be
- SETT_NAME: name of the demand centers (not all demand centers are settlements).
