Both previous responses are correct. Each map, list of codes, unit numbers, etc. are attached to a County, Agency, or TRS page. What ever has the information you want to submit corrections to, is the correct page to submit from. If you have a image that needs to be updated, send in a submission with your email address so that the DB Admin can contact you and get the image transferred. There is no method (currently) to submit an attached image with a submission.
