IBM Informix Spatial Reader/Writer

Licensing options for this format begin with FME Desktop Professional Edition.

FME’s Informix Spatial Reader/Writer module (referred to as Informix Spatial in this chapter) enables FME to read and write spatial and attribute data inside Informix databases.

Note: Informix Connect software must be installed on the same machine as FME.


Informix Spatial can read from databases which are spatially enabled, but the tables may or may not have spatial information stored.

Reader Overview

FME considers an Informix Spatial dataset to be a database containing a collection of relational tables together with their geometry. The tables to be read are defined in the workspace. Arbitrary WHERE clauses are supported.

Writer Overview

The Informix Spatial writer module stores both geometry and attributes into spatially-enabled Informix databases. The Informix Spatial writer provides the following capabilities:

  • Table Creation: The Database writer uses the information within the FME workspace to automatically create database tables as needed.
  • Coordinate System: Checks for a coordinate system and if a matching one is not found, then it will create one automatically. The matching criteria is the OGC WKT definition of the coordinate system.
