Google Maps Address Extractor is a JavaScript code that extract
addresses under a polygon, rectangle or circle using Google Maps API.
The extracted addresses can be downloaded in CSV format.
You can specify which fields (street, city, state, country or postal code) to extract.
You can specify the language of the addresses to extract.
Select the language in which to extract the addresses.
Enter the distance in meters.
This is very important here.
If you specify 20 as distance, then it will get each point
within the polygon/circle/rectangle at the distance of 20 meters and
reverse geocode it to get its address. If you specify lower value (e.g. 5 or 10),
then it will extract almost all addresses. If you specify a large value (e.g. 500),
then there is a chance that some addresses will be skipped. We have made this value
configurable so that end user would be able to decide this as per their requirements
based on different areas. As there is no built-in feature to extract all addresses
under a polygon/circle/rectange, therefore, we are using this algorithm.
Please note that if you specify a small value (e.g. 5 or 10 meters),
then it will send large number of requests to geocoding API.
In case if smaller value, there is a chance that duplicate
addresses are extracted, however, our algorithm will remove the duplicates
and will download the unique addresses only. Also, if you need to extract
all addresses from a large area (e.g. a city or town), we suggest to do this
in multiple steps i.e. select smaller areas and download its addresses.
It is recommended because if you want to extract large number of addresses and if the
process is in the middle and you accidently close the browser window or
refresh the page, then you will lose the already processed data. Therefore, we
recommend to extract addresses from smaller areas and then download them.
From the Options dialog, select the fields (street number/name,
city, state, country, postal code etc.) that you want to extract and download.
After specifying all the options, click OK button.
Draw a Polygon:
If you want to extract addresses under a polygon, then click Draw Polygon
and draw the polygon on the required area of the map.
Draw a Rectangle:
If you want to extract addresses under a rectangle, then click Draw Rectangle
and draw the rectangle on the required area of the map.
Draw a Circle:
If you want to extract addresses under a circle, then click Draw Circle
and draw the circle on the required area of the map.
Extract Addressses:
Click the Extract Addresses link from the navigation bar to start
the process of extracting the addresses. It will show the progress as addresses
are being extracted. Once the process is completed, then the progress dialog will close.
Download CSV:
Click the Download link to download the CSV file containing all
the addresses extracted.
Also enable JavaScript Maps API and Geocoding API.
Open index.html page.
Add your key in the following line (replace YOUR_API_KEY with your Google Maps API key):
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?libraries=places&key=YOUR_API_KEY"></script>
