Esri Geodatabase (File Geodb Open API) Reader/Writer

The Esri Geodatabase (File Geodb Open API) reader and writer modules allow FME to store data in and retrieve data from Esri’s File Geodatabase, based on the File Geodatabase API.

No additional software is required to use this format, but less functionality is available than some other Esri Geodatabase formats.

Format Notes

The Esri Geodatabase (File Geodb Open API) reader/writer provides Geodatabase support without an installed Esri product on Windows and Linux; however, it is a limited set of geometry and works only with 10.0 File Geodatabases or higher. For example, annotation is unsupported.

Overview

The Geodatabase reader and writer translates several different types of features:

  • reading and writing of point, line, polygon, and multipoint feature classes
  • partial reading of some of the other File Geodatabase types (e.g., dimensions, parcel fabrics) exposed using the basic geometric types listed above
  • reading and writing of non-spatial tables

Reader Overview

The reader extracts data from the selected File Geodatabase using the File Geodatabase API.

ArcGIS feature classes and tables become FME feature types, and ArcGIS features and rows become FME features. For feature classes within a feature dataset, the FME feature type name is formed as follows: <feature dataset name>/<feature class name>.

As with other database readers in FME, the Format Parameters are used to determine which feature classes and tables to read. WHERE clauses and bounding box constraints can be used to further limit the data read.

Writer Overview

The writer exports data to a new or existing File Geodatabase using the File Geodatabase API.

Note that, because they are considered to have complex behavior, the Geodatabase API writer does not support writing to tables that participate in a relationship.

Other tables/feature classes that are not supported:

  • Annotation and Dimension feature classes
  • Relationship Classes
  • Networks (GN and ND)
  • Topologies
  • Terrains
  • Representations
  • Parcel Fabrics
