You can use the Google Spreadsheets add-on called Geosheets to create your map. That way your map will automatically update in realtime whenever data changes in your spreadsheet. I actually found that using Google Fusion tables solved this problem so that when that was updated, so was the map.
One source stated that this means, in essence, Google Maps is updated constantly – literally, every second of every day! Today, Google Maps contain information, ratings, and reviews of about 200 million places around the world.
Google Maps doesn’t update in real-time, or even with a great deal of frequency. In fact, for some places, the maps may be years out of date! Many people have wondered how often Google Maps updates and how to find out when it’s going to update next for a given spot.
Google doesn’t have a fixed schedule of updates for Google Maps, or if it does, it doesn’t release that information to the public. Regardless, the update frequency depends on what part of the world is getting imaged from empirical data collection. Of course, multiple areas get imaged at the same time.
Even if Google does that, it is not at all feasible. Therefore, Google comprises. It plans the updates according to the above factors. But it also has a rule that no region of the map should be more than three years old. Every image has to be updated within three years.
Unfortunately nothing really changed with My Maps. Its stil a one off import from Sheets. And Google haven’t added a API for My Maps to be able to ‘automate’ updates. There is a free credit (of $200/month ) on the Maps API/Platform, so if stay under then, it shouldn’t cost. But it will need coding. Mainly javascript, to create a map.
Update your Google Maps app so that you can use features like sharing your location. To use the most recent app features, download the latest version of the Google Maps app. Open the Google Maps app .
