| - | ^ Name ^ Type ^ Description ^ | + | ^ Name ^ Type ^ Description ^ |
| - | | Source | [[Categorical Map Type|Categorical Map ]] | Map containing the features to which distances will be calculated. A feature is represented by a non-null value. Data cell type of this map must be "Signed 32 Bit Integer" or an error will be reported. | | + | | Source | [[Categorical Map Type]] | Map containing the features to which distances will be calculated. A feature is represented by a non-null value. Data cell type of this map must be compatible with "Signed 32 Bit Integer" or an error will be reported. | |

| - | | Mask | [[Categorical Map Type|Categorical Map ]] | A map used to mask the distance calculation on its null cell areas. Data cell type of this map must be compatible with "Signed 32 Bit Integer" or an error will be reported. | None | | + | | Null Value | [[Null Value Type]] | Null value of the distance map. | Default((Based on the given Cell Type input)) | |
| - | | Cell type | [[Cell Type Type|Cell Type ]] | Data cell type. | Signed 32 Bit Integer | | + | | Truncate Distance | [[Boolean Value Type]] | If true, distance values that exceed the greatest value of the output map will be truncated, instead of reporting an error. | False | |
| - | | Null Value | [[Int Type|Int ]] | Null value of the distance map. | -2147483648 | | + | |
| - | | Truncate Distance | [[Bool Type|Bool ]] | If true, distance values that exceed the greatest value of the output map will be truncated, instead of reporting an error. | False | | + | |
| - | | Ignore Unreachable Sources | [[Bool Type|Bool ]] | If true, feature cells completely surrounded by other feature cells are ignored. | True | | + | |
| - | | Ignore Cross Inside Sources | [[Bool Type|Bool ]] | If true, feature cells surrounded by other feature cells on the horizontal and vertical axis will be ignored. To have an effect, "Ignore Unreachable Sources" must also be true. | True | | + | |
