tGoogleGeocoder
Converts human-readable addresses into geographic coordinates.
tGoogleGeocoder accesses the Google
Places API over HTTP request to obtain geographic coordinates according to the address
information you provided.
For further information about Google Places API, see Google Places API.
Each data row needs one or several calls to the Places API. The
quota will depend on the license provided by Google. Make sure not
to run the component on a data set that exceeds your quota,
otherwise you will get error messages and addresses will not be
corrected.
For further information about the usage limits of Google Places
API, see Usage Limits and Billing.
For further information about the terms of services of Google
Places API, see Terms of Service.

Obtaining geographic coordinates using address information
This scenario applies only to Talend Data Management Platform, Talend Big Data Platform, Talend Real Time Big Data Platform, Talend Data Services Platform, Talend MDM Platform and Talend Data Fabric.
This scenario describes a three-component Job which send HTTP request to Google Places
API and obtain geographic coordinates based on the address we provided.

Setting up the Job
-
Drop the following components from the Palette onto the design workspace: tFixedFlowInput, tGoogleGeocoder and tLogRow
-
Connect tFixedFlowInput to tGoogleGeocoder and tGoogleGeocoder to tLogRow
using Main links.
Configuring the components
-
Double-click tFixedFlowInput to display
its Basic settings view to define its
properties. -
Click Edit schema to open a dialog box
that displays the data structure of input data and define the data you want
to pass to tGoogleGeocoder, two columns in
this scenario, AddressID and
Address. Then, click OK to close the dialog box. -
Click Use Inline Table in the Mode area of the Basic
settings view of tFixedFlowInput, and click the [+] button to add one column to the table. -
Fill in the field in the AddressID column with
1
and the Address column with
“500 Oracle Parkway,Redwood Shores, CA 94065
“. -
Double-click tGoogleGeocoder to display
its Basic settings view and define its
properties. -
Select Address from the Address Column list and let the rest of settings
as they are. -
Double-click tLogRow to display its
Basic settings view and define its
properties. -
Select Vertical (each row is a key/value
list) in the Mode area and
Print unique name in the Title printing mode area.
