| - | This functor creates a map from table values. | + | Builds a map from three lookup tables that describe, per cell identifier, a cell's value and its line and column coordinates. |
| ===== Inputs ===== | ===== Inputs ===== | ||
| - | ^ Name ^ Type ^ Description ^ | + | ^ Name ^ Type ^ Description ^ |
| - | | Value Table | [[Lookup Table Type|Lookup Table]] | Input table containing the cell values. The table keys represent the cell identifier. | | + | | Value Table | [[Lookup Table Type]] | Table of cell values, keyed by cell identifier. | |
| - | | Line Table | [[Lookup Table Type|Lookup Table]] | Input table containing the lines (Y coordinates). The table keys represent the cell identifier. The map upper line uses 1 as the line number. | | + | | Line Table | [[Lookup Table Type]] | Table of cell lines (Y coordinates), keyed by cell identifier. The topmost line is 1. | |
| - | | Column Table | [[Lookup Table Type|Lookup Table]] | Input table containing the columns (X coordinates). The table keys represent the cell identifier. The map leftmost column uses 1 as the column number. | | + | | Column Table | [[Lookup Table Type]] | Table of cell columns (X coordinates), keyed by cell identifier. The leftmost column is 1. | |
| - | | Map Format | [[Map Type|Map]] | Map used to define the output format. | | + | | Map Format | [[Map Type]] | Map supplying the output's spatial format (geometry and projection). | |
| - | | Cell Type | [[Cell Type Type|Cell Type]] | Data cell type. | | + | | Cell Type | [[Cell Type Type]] | Cell type of the output map. | |
| - | | Null Value | [[Null Value Type|Null Value]] | Null Value. | | + | | Null Value | [[Null Value Type]] | Null value of the output map. | |
| ===== Optional Inputs ===== | ===== Optional Inputs ===== | ||
| - | ^ Name ^ Type ^ Description ^ Default Value ^ | + | ^ Name ^ Type ^ Description ^ Default Value ^ |
| - | | Result Is Sparse | [[Bool Type|Bool]] | If true, this flag forces the output map to be created as a sparse raster set. Sparse raster set stores only non-null value cells, minimizing storage memory, yet increasing access time. | False | | + | | Result Is Sparse | [[Boolean Value Type]] | If true, forces the output map to be created as a sparse raster set, which stores only non-null cells, trading slower access time for reduced storage. This is an advanced port. | No | |
| ===== Outputs ===== | ===== Outputs ===== | ||

| - | | Map | [[Map Type|Map]] | The output map. | | + | | Map | [[Map Type]] | Map built from the given cell values and coordinates. | |

| - | ===== Internal Name ===== | + | A cell identifier missing from Value Table, Line Table, or Column Table raises an error. |

| + | A cell identifier present in Line Table and Column Table but omitted from Value Table is filled with null in the output map. | ||
