Standardize Boolean Input |
|
Standardize a boolean map:
Standardization possibilities are slightly different for factors and for constraints.
For boolean maps standardization is easy. The user only needs to specify a value to be given to the 'true' and the 'false' pixels.
Dialog box options:
Value for TRUE: | Type a value between 0 and 1 to be given to input pixels with value True. The default value to be assigned is 1.000. |
Value for FALSE: | Type a value between 0 and 1 to be given to input pixels with value False. The default value to be assigned is 0.000. |
Tip: When a factor (a benefit or a cost) with a boolean domain has been standardized, the criteria tree viewer shows information about the way the factor is standardized, see the first column below.
| ||
Criterion name--Std:T=ValueT, F=ValueF | i.e. True input values are assigned ValueT; False input values are assigned ValueF |
When a map is used as a constraint, options are simplified because the user only needs to specify a condition that a pixel should satisfy in order to include it in the output.
Dialog box options:
|
This means that all input pixels with value True will be included in the output map; all pixels with value False will be excluded from the output. |
|
This means that all input pixels with value False will be included in the output map; all pixels with value True will be excluded from the output. |
Tip: When a constraint with a boolean domain has been standardized, the criteria tree viewer shows information about the way the factor is standardized, see the first column below.
| ||
Criterion name--Std:True | areas with value True in the input map will pass; areas with value False in the input map will obtain output value 0. | |
| ||
Criterion name--Std:False | areas with value False in the input map will pass; areas with value True in the input map will obtain output value 0. |
