This causes the perimeter of the polygon to be displayed as well as a circle at each vertex. In this example, a polygon is being drawn using the Line and Circle marks. Since the same fields are used for the latitude and longitude of the vertices, any shape that can be represented with a simpler type (for example, a line drawn as dots, or a polygon drawn as the perimeter line with no fill) may be drawn multiple times with each selected Mark type.

The feature type name will be the name of the TDE file created. The writer provides the capability to create a single file and table with an arbitrary number of rows and columns. The TDE writer writes features as rows into a single table in an extract file per feature type in FME. This writer supports creation of Tableau 9.1-9.2 TDE files.

Each feature type in FME is written to a separate TDE file. WGS84 is the required coordinate system for TDE, but FME will reproject features if necessary.Įach attribute in FME is mapped to a column in a TDE file, and spatial information is put into additional columns during the writing process. Because of this, a single feature in FME may be represented in a TDE file with many rows, depending on the size and complexity of the geometry. It can be used with Tableau products including Tableau Desktop and Tableau Server.Įach vertex in a piece of geometry must be stored in a separate table row.

Each TDE file will have a single table named Extract present within the file that matches the attribute names and types supplied on the writer feature type properties.Ī Tableau Data Extract file is a compressed, memory-mapped file that uses columnar store and supports standard, non-spatial data types as well as certain spatial geometry types. The base name of the TDE file will match the feature type name. Tableau is a business analytics and data visualization tool with optional online components for displaying visualizations in web pages.įME provides write access to Tableau Data Extract (.tde) files (also known as extracts). Licensing options for this format begin with FME Professional Edition. You are here: New Formats for 2016+ Tableau Data Extract (TDE) Writer Tableau Data Extract (TDE) Writer
