I'm trying to create a map similar to Pokemon GO maps, using this URL.
But I want to show few random markers(so, they look like pokestops / gyms). Can anyone help me understand the URL or modify it to show markers.
Also, The final result should be a URL, no xml or API.
It seems like you're new and trying to create static maps with custom markers. Usually, you should only post development related questions, but I'll give you a hint with where to go.
The best resource for the map you are saying is the Documentation on Static Maps: https://developers.google.com/maps/documentation/static-maps/intro
Then in the markers section, you can learn more about adding custom markers: https://developers.google.com/maps/documentation/static-maps/intro#Markers
If you encounter any issues with Static Maps, just post another question with your sample request or code and many avid community members will be able to help you :)
