Google is sending out a call for all amateur cartographers.
As of this week, people all over the country can edit online maps of the U.S. through Google Map Maker. The Internet search giant wants users to help fill in the details on its existing Google maps by drawing building outlines, adding business names, mapping college campuses, and sketching out bike or walking paths. Google opened the Map Maker feature to U.S. cities after years of successful user edits on maps in more than 180 other countries. Volunteer moderators will check the changes for accuracy before they appear on the official Google map. Aspiring map makers can get started at www.mapmaker.google.com.
