How Can Google's Geocoding API Improve Address Standardization in MS Access 2013?

Address Standardization within a Database

Standardizing Locations in MS Access 2013

In MS Access 2013, maintaining standardized addresses can be challenging, as different variations may exist for the same location. While simple queries based on partial matches can identify inconsistencies, they often lack precision.

Leveraging Google's Geocoding API

Instead of relying solely on database queries, a more robust solution involves utilizing Google's Geocoding API. This API can analyze addresses and return standardized formats, regardless of variations in input.

For example, both "500 S Main St,Providence RI 02903" and "500 South Main Steet,Providence RI 02903" would be standardized to "500 S Main St, Providence, RI 02903, USA" by the API.

VBA Example for Google API Integration

Using VBA, you can integrate the API into your MS Access database:

' Reference: Microsoft XML, v3.0

Dim httpReq As New MSXML2.ServerXMLHTTP
httpReq.Open "GET", "https://maps.googleapis.com/maps/api/geocode/json?address=500 South Main Steet,Providence RI 02903", False
httpReq.send
Dim response As String
response = httpReq.responseText

The variable "response" will contain a JSON object representing the standardized address information.

Benefits of Using the Geocoding API

• Accurate Standardization: The API leverages Google's extensive geographical database to provide highly accurate standardization.
• Versatility: The API can handle various address variations and automatically identify the correct format.
• Efficiency: Integrating the API into your database can automate the standardization process, reducing manual effort and errors.
• Consistency: By using a centralized service for standardization, you can ensure consistency across all your database records.
