Generate Selected Maps   

 

 

Generate the currently selected map(s), i.e. calculate one or more SMCE output maps.

When an output map of the main goal is selected, the composite index map for that alternative is calculated. A composite index map contains the accumulated suitability for all the criteria, standardized and weighed as specified in the criteria tree.

A composite index map has values between 0 and 1:

To calculate one or more selected maps:

After selecting an output map of the main goal, an intermediate output map of a subgoal, or the main goal, or a subgoal in the criteria tree viewer, you can use:

Depending on the selection, one or more output maps will be calculated:

  1. When a single output map of the main goal is selected and the Generate Selected Maps option is used, the composite index map of the current alternative will be calculated and shown.
  2. When a single output map of a subgoal is selected and the Generate Selected Maps option is used, the single selected output map will be calculated and shown.
  3. When the main goal is selected and the Generate Selected Maps option is used, all composite index maps, i.e. all SMCE output maps of all alternatives, will be calculated and shown.
  4. When a sub goal is selected and the Generate Selected Maps option is used, all output maps of the selected sub goal, i.e. for all alternatives, will be calculated and shown.

 

Note: For all cases above, the generated output will be correct, although any possible intermediate output maps are not automatically recalculated. This is because the calculation simply takes input maps into account; any intermediate output maps are regarded as extra by-products.

Dialog box options:

Show after calculation:

Select this check box if you wish to show the output map(s) immediately after calculation. By default the check box is selected.
Clear this check box to only calculate the map(s).

Tips:

Composite Index maps (SMCE output maps) use system domain Nilto1 and a matching representation from red (0, unsuitable) to green (1, suitable).
