Hundreds of Markers - Create maps with hundreds of markers.We wanted creating an online map to be as easy as it is to create a Microsoft Word document. Our goal with Atlist was to make a tool that allowed anyone to create their own custom maps. So while I think it’s great, I am slightly biased. Now I should mention: I’m a co-founder of Atlist.
I’d suggest Atlist if you need a custom Google Map with multiple markers.
