There are a few ways to map multiple locations in order to create a custom Google map:
EasyMapMaker is one of the easiest and fastest ways to create a custom Google Map. Our high speed address processing engine can process over 5,000 addresses a minute. We use Google's Maps API and have added some popular features such as pin labels. Creating a map using our system requires data (normally from excel or a spreadsheet) with address information (such as address, city, state, zip (postal) code) or latitude and longitude coordinates. Other information can used on the map for things such as filtering, pin labels, or pin descriptions.
If data is in an excel or other spreadsheet file and has address information, it can be used to create a custom map.Create A Custom Map Now
