Google has opened up Google MapMaker to all Google Account users to edit any spot in the United States. With the philosophy of "you know your neighborhood best," Google wants everyone to jump online to tag their favorite bike paths, coffee shops, college buildings and more.
Google Mapmaker is a product where Google allows the general public to draw shapes to tag buildings, parks, paths, rivers and more inside a Google map product. Mapmaker has been around since 2008.
To prevent spam and verify accuracy of the information, each of the edits made need to be verified by other Google users before they are made live. To get people to assist in editing, Google states that if you review some edits, your edits will get reviewed faster. If you don't want to edit, using Google Earth you can watch others as they edit live.
How To Edit
To make edits in Google Mapmaker, navigate to the location you want to edit and click one of the icons in the "add" toolbox. You can add a point, a line or a polygon shape. When you do, Google presents you with a series of fields with which to label your new location. These labels include name, street address, categories, web address, email, and many more context-specific tags.
