====== Calculate Categorical Map2 ======

===== Description =====

**This functor is deprecated.** It computes a new categorical raster map by evaluating an algebraic or logical expression independently for every cell of the output map, in exactly the same way as [[Calculate Categorical Map]]. It is kept only so that older models built with it continue to load and run; new models should use [[Calculate Categorical Map]] instead.

===== Inputs =====

^ Name  ^ Type  ^ Description  ^
| Expression  | [[Image Expression Type]]  | Algebraic or logical formula used to compute each output cell's category code. Must be enclosed in square brackets ''[ ]'' in EGO Script.  |

===== Optional Inputs =====

^ Name  ^ Type  ^ Description  ^ Default Value  ^
| Cell Type  | [[Cell Type Type]]  | Data type for each output cell.  | Signed 32 Bit Integer  |
| Null Value  | [[Null Value Type]]  | Sentinel value representing "no data" in the output.  | .default  |
| Result Is Sparse  | [[Boolean Value Type]]  | If true, only non-null cells are stored, saving memory at the expense of random-access speed. This is an advanced port.  | No  |
| Result Format  | [[Map Type]]  | Reference map whose spatial format (extent, resolution, projection) is applied to the output; its category information, if any, is ignored. This is an advanced port.  | .none  |

===== Outputs =====

^ Name  ^ Type  ^ Description  ^
| Result  | [[Categorical Map Type]]  | Computed categorical output map. Its dimensions come from the connected input maps, or from Result Format when given.  |

===== Group =====

[[Functor List#Map Algebra | Map Algebra]]

===== Notes =====

Behaves identically to [[Calculate Categorical Map]] in every respect except its internal name; see that functor's Notes for the hook mechanism, image virtualization, and null-value handling that both share.

This functor is obsolete and is retained only for backward compatibility with existing models.
