Feature Representation

Features read from Google Fusion Tables 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 fusion table have the destination table as their feature type, and attributes as defined on the DEF line.

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

googlefusiontables_type

The type of geometric entity stored within the feature are listed below:

googlefusiontables_no_geom

googlefusiontables_point

googlefusiontables_line

googlefusiontables_polygon

googlefusiontables_collection

Features read from, or written to, Google Fusion Tables Spatial also have an attribute for each column in the table. The feature attribute name will be the same as the source or destination column name.

The attribute and column names are case-sensitive.

No Coordinates

googlefusiontables_type: googlefusiontables_no_geom

Features with no location columns or unsupported location data are tagged with this value when reading or writing to or from Google Fusion Tables.

Points

googlefusiontables _type: googlefusiontables _point

Features tagged with this value consist of a single point. Both singular points and aggregates of points are supported. On read, points are created by by KML data or a latitude/longitude pair within one location column. Point aggregates are created through the <MultiGeometry> KML tag or multiple columns with single points and these will become collections. Single point features will become points in Google Fusion Tables.

Line

googlefusiontables _type: googlefusiontables _lines

Linear features are tagged with this value when reading or writing to or from Google Fusion Tables. A linestring consists of one or more ordered point line segments. Linestrings can only be created via the <LineString> KML tag. Separate linestrings created using the <MultiGeometry> KML tag or linestring created in different location columns will become collections in Google Fusion Tables.

Polygon

googlefusiontables _type: googlefusiontables _polygon

Area or polygon features are tagged with this value when reading or writing to or from Google Fusion Tables. Both single-part and aggregate area features are supported. An area feature may be either a polygon or a donut polygon. Area aggregates will become collections while singular areas will become polygons in Google Fusion Tables.

Collection

googlefusiontables _type: googlefusiontables_collection

When reading location columns within Google Fusion Tables, KML data that uses the <MultiGeometry> tag will become collections. Multiple geometry columns within the same row will also become a collection but each geometry will retain their original column name.
