How to Scrape data from google map based pop up location?

Hello everyone,
I'm very much new to this field and had just started exploring.
I want to scrape the data of latitude and longitude related with each school with specific school code that I will provide.
Please can anyone help me out how to proceed with the work because right now I need to copy and paste lat/long values from source code which is very tedious task.
Your help will be very kind.
