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 topic.

GeoMedia features consist of geometric shapes which have their associated attributes as part of their definition. All GeoMedia features contain an fm0_type attribute, which identifies the geometric type. The feature contains additional attributes specific to its geometric type.

The common attributes of all GeoMedia features are shown in the following table. The table name is used as the feature type.

Attribute Name

Contents

fm0_type

The GeoMedia geometric type of this entity.

Range:

fm0_point

fm0_line

fm0_arc

fm0_area

fm0_text

fm0_collection

fm0_none

Default: No default

The blob breakdowns for the composite (aggregate), boundary (donut) and collection (aggregate) features are not mentioned below with the simple features, each of which has its corresponding attributes and blob data parsed.

Note: Geometries from FME do not map exactly to GeoMedia geometries. Usually, however, this is not an issue because although some of the internals of the geometries may be changed, their appearance in GeoMedia is still the same.

Additional attributes are described below.

Lines

Arcs
