Feature Representation
In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Attributes), this format adds the format-specific attributes described in this section.
When writing a raster using the Z-Map Grid writer, the values of these attributes are ignored, and the corresponding properties are derived from the input raster.
Attribute Name | Contents |

zmap_type | zmap_raster |
zmap_max_x |
Coordinate of the raster’s bounding box. Range: Any real number. Default: No default |
zmap_max_y |
Coordinate of the raster’s bounding box. Range: Any real number. Default: No default |
zmap_min_x |
Coordinate of the raster’s bounding box. Range: Any real number. Default: No default |
zmap_min_y |
Coordinate of the raster’s bounding box. Range: Any real number. Default: No default |
zmap_null_value |
