In a Google Groups thread, a number of small businesses are noticing that their location marker isn't quite on target; they would like to edit it out. In the past (and unfortunately I don't have a screenshot), there was a feature that would enable users to "edit incorrect marker location." (A similar feature is discussed in our screenshot tour of the "move the map marker".) Google has acknowledged that they removed this, thinking that it wasn't important.
However, a few business owners admit that the location marker is not pointing to their business location as accurately as they'd like, and they want to change it. The only way around doing this, at the moment, is to delete the entire business and start again from scratch. Naturally, since there's a lot of information that goes into entering a business on Google, it's not the ideal solution.
With the few people who are impacted, it's probably true that a lot of other individuals are affected but haven't used Google Groups to voice their concern. Maps Guide Jen, however, says that there is "clear evidence" that this feature is needed and Google will be adding it back in soon.
