Foursquare Studio Data Reader Feature Type Parameters

To access feature type parameters, click the gear icon on a feature type in the workspace. This opens the Feature Type Parameter Editor.

Tip  To always display the editor in FME Workbench, you can select View > Windows > Parameter Editor.

General

All feature types share similar General parameters, which may include Feature Type Name, Reader or Writer information, and Geometry.

In most Writer Feature Type parameter dialogs, you can also control Dynamic Schema Definitions. Some database formats accept Table or Index Qualifier prefixes on the output table feature type.

Dataset

Geometry Column Name

Enter the name of a user attribute on the schema to generate FME geometry on output features from. The FME geometry will be added to output features in addition to the attribute values output on the feature.

The geometry column should correspond to a column identified in Foursquare Studio as geo, which contains values specified as Well-Known Text (WKT), or using a JSON definition. The JSON definition should use the same syntax used to specify geometry on GeoJSON features. For example:

`{“type”: “LineString”, “coordinates”: [[0.0,0.0],[1.0,1.0],[2.0,2.0]}`

Parameter Value

Description

(default)

The default value for this parameter is the value that was specified for Geometry Column Name when the reader was placed.

geometry

If the geometry column in the dataset exists, the reader will attempt to create geometry on output features from these values.

geom

If the geom column in the dataset exists, the reader will attempt to create geometry on output features from these values.

_geojson

If a .geojson file was uploaded to Foursquare Studio, any geometry information it contains will be represented in the _geojson column.

custom value

If a custom value (column name) was specified in the reader parameters, the reader will create geometry from values in the custom column.
