Actian Ingres Spatial and Non-Spatial Feature Representation

Features read from Ingres Spatial consist of a series of attribute values and geometry. The feature type of each feature is defined in its Feature Type dialog. .

The geometry object model in Ingres Spatial follows the OGC Simple Features Specification 1.1. For more information, see http://www.opengeospatial.org/.

Features written to the database have the destination table as their feature type, and attributes as defined in the Feature Type parameters.

In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format also adds format-specific attributes (Format Attributes).

Attribute Name	Contents
ingres_type	The type of geometric entity stored within the feature. The valid values for the object model are listed below: ingres_point ingres_multipoint ingres_linestring ingres_multilinestring ingres_polygon ingres_multipolygon ingres_geometrycollection ingres_none

ingres_type

The type of geometric entity stored within the feature. The valid values for the object model are listed below:

ingres_point
ingres_multipoint
ingres_linestring
ingres_multilinestring
ingres_polygon
ingres_multipolygon
ingres_geometrycollection
ingres_none

Features read from, or written to, Ingres Spatial 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-insensitive.
