Feature Representation (Spatial Only)
Features read from Netezza Spatial consist of a series of attribute values and geometry. The feature type of each feature is as defined on its DEF line.
Features written to the database have the destination table as their feature type, and attributes as defined by the DEF line.
In addition to the generic FME feature attributes that FME Workbench adds to all features, the Netezza Spatial reader module adds the format-specific attributes described below:
Attribute Name |
Contents |
netezza_type |
The type of geometric entity stored within the feature. The valid values for the object model are listed below: netezza_none netezza_point netezza_linestring netezza_polygon netezza_geometry netezza_geometrycollection |
Features read or written by Netezza Spatial modules also have an attribute for each column in the database table. The feature attribute name will be the same as the source or destination column name. The attribute and column names are case-sensitive.
The following table summarizes netezza_type support in the Netezza Spatial reader and writer.
