Calculate Categorical Map
Description
This container calculates a categorical map using algebraic/logical expression involving maps, tables and values.
Inputs
Name | Type | Description |
---|---|---|
Expression | Image Expression | Algebraic or logical expression used to calculate the output map. |
Optional Inputs
Name | Type | Description | Default Value |
---|---|---|---|
Cell Type | Cell Type | Data cell type | Signed 32 Bit Integer |
Null Value | Null Value | Null value | Default1) |
Result Is Sparse | Bool | If true, the resulting map is created as a sparse image. Sparse images have the advantage of storing only the cells containing non-null values, but they have diminished access time. | False |
Result Format | Map | Map representing the output format. Any category information presents in the given map is not used as part of the map format. | None |
Outputs
Name | Type | Description |
---|---|---|
Result | Categorical Map | Output map of classes or categories |
Group
Notes
The expression result is calculated as a real value and converted to the data cell type of the output map.
If the calculation of the expression diverges or if the data cell type is not large enough, the corresponding cell is filled with the null value.
The category information for the resulting map is automatically derived from its cell values.
The list of mathematical and logical operators that can be employed in the logic/algebraic expression can be found in the image expression reference.
The maps used by the “Calculate Categorical Map” must be provided by a corresponding Number Map, the tables must be provided by a corresponding Number Table and the values must be provided by a corresponding Number Value.
