Calculate Map
Description
This container calculates a 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 | Int | Null value | -2147483648 |
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 |
Outputs
Name | Type | Description |
---|---|---|
Result | Map | Output map. |
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.
A list of mathematical and logical operators that can be employed in the logic/algebraic expression can be found in the image expression reference.
