RandomLongitude

The RandomLongitude transformer is designed to generate random longitude values for specified database columns, enhancing datasets with realistic geographic coordinates suitable for a wide range of applications, from testing location-based services to anonymizing real geographic data.

Parameters

Name	Description	Default	Required	Supported DB types
column	The name of the column to be affected		Yes	float4, float8, numeric
keep_null	Indicates whether NULL values should be preserved	false	No	-

Description

The RandomLongitude transformer leverages the faker library to produce random longitude values within the globally accepted range of -180 to +180 degrees. This flexibility allows the transformer to be applied to any column intended for storing longitude data, providing a simple yet powerful tool for introducing randomized longitude coordinates into a database.

Example: Populate random longitude for the locations table

This example shows how to use the RandomLongitude transformer to fill the longitude column in the locations table with random longitude values.

RandomLongitude transformer example

- schema: "public"
  name: "locations"
  transformers:
    - name: "RandomLongitude"
      params:
        column: "longitude"
        keep_null: false

This setup ensures that all entries in the longitude column receive a random longitude value, replacing any existing non-NULL values. If keep_null is set to true, then existing NULL values in the column will remain unchanged.
