Hello Ivanbranco! No, my edits are not based from Google Maps! I actually live in this area and traverse them on foot regularly! I have been all around the Chestertown area on foot! These changes are accurate and actually up to date, ahead of what's displayed on Google Maps. For example, the "Village at Chestertown" is a new housing community built at the end of Scheeler Road, down Silver Heel Rd and Floating Cloud Dr, and the homes have not appeared on Google Maps yet due to construction being completed only a month ago. Thank you!
