Teradata Spatial Feature Representation

Feature types correspond to the database table with the same name, and attributes correspond to columns of the same name.

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

teradata_type

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

  • teradata_point
  • teradata_multipoint
  • teradata_linestring
  • teradata_multilinestring
  • teradata_polygon
  • teradata_multipolygon
  • teradata_collection
  • teradata_none

Teradata Non-Spatial can read spatial features if they exist within the table being read. However, writing spatial features containing geometry into a table requires the Teradata Spatial writer.

No Geometries

teradata_type: teradata_none

Features with no geometries are tagged with this value when reading from Teradata.

Point

teradata_type: teradata_point

Features tagged with this value consist of a single point.

MultiPoint

teradata_type: teradata_multipoint

Features tagged with this value consist of a collection of points.

LineString

teradata_type: teradata_linestring

Features tagged with this value consist of a single line.

MultiLineString

teradata_type: teradata_multilinestring

Features tagged with this value consist of a collection of lines.

Polygon

teradata_type: teradata_polygon

Features tagged with this value consist of a linear polygon or donut.

MultiPolygon

teradata_type: teradata_multipolygon

Features tagged with this value consist of a collection of linear polygons and/or donuts.

GeometryCollection

teradata_type: teradata_geometrycollection

Features tagged with this value consist of a possibly heterogeneous aggregate.
