Google Maps Scraping in Pure Java
Google Maps scraping demands a solid understanding of code, browser emulation, proxies, and reCAPTCHA solvers. Google has dynamic content. Therefore, you should be able to adapt to any changes that it may make.
Primarily, you will need to mimic the behavior of a real user via browser emulation. Utilizing Selênio or other browser emulators could be a practical approach. Second, you must use procuradores if you wish to protect your office/home IP address, enabling you to request websites from the IPs of other users.
Google can perhaps display you with reCAPTCHA and bind it to some of your IPs, despite all that set of tools, when you have fair usage. For that reason, you can add a solucionador reCAPTCHA if you do not wish to alter your IP address each time you encounter a reCAPTCHA.
Moreover, you should always be ready for the possibility that Google will alter the content of its website. You can accomplish this by conducting testing daily.
Despite the fact that implementation of the scraper could take a while, it is still possible to construct and maintain it. For additional information, take a look at this comprehensive guide that explains how to scrape Google Maps by utilizing Python and Selenium: Como extrair dados do Google Maps com Python e Selenium.
