Google Fusion Tables (Spatial) Writer Parameters

The Google Fusion Tables Writer produces a Google Fusion Table with a row for each feature. New tables can be created for each specified feature type or, alternatively, rows can be written to existing tables that match the feature type names. In both cases, features may cause rows to be inserted into the table, and existing tables can have rows updated or deleted based on matching input features, which are based on key update columns.

Google Fusion Tables formats allow you to easily upload and manage data in the cloud (for example, spreadsheets and comma-separated value [CSV] files).

Google Fusion Tables makes it easy to create visualizations like maps, timelines and other charts, and either share these with collaborators or make them publicly accessible. Users can also merge datasets that belong to different owners.

It offers a REST API to run SQL-like queries to manage tables (create, delete), manage data rows (insert, update, delete), and query the table for all rows that match spatial or data conditions. The results of queries can be output to a CSV file, or used in the Google Maps API or Google Chart Tools.

There are two versions:

  • Google Fusion Tables Non-spatial, which supports all the column types as attributes,
  • Google Fusion Tables Spatial which, for convenience, creates geometry from location columns

Both versions can read from and write to private and public tables.

Please note that the Google Fusion Tables Spatial writer will only write KML geometry as attributes of the feature.

Google Fusion Tables allows for blank and duplicate column names. Blank columns cannot be written to with a writer and duplicate columns will receive the same value. Unique named columns are always used when creating tables.

Note: It is recommended that existing table columns be provided with unique names before writing to them. This is a simple step through the Google Fusion Tables web interface under Edit > Modify Columns.

Public tables can be written to if access permissions allow by specifying the numeric table identifier as the name of the writer feature type.
