How can I report misplaced portals in Ingress?
Yesterday a lot of new portals appeared. Some of them are misplaced more than a hundred meters. How do I report those and supply a better position?
You can report an issue about portal locations at Ingress Support Page, press Contact Us then choose Report an issue with a portal. Then, report your issue ;)
EDIT 03/12/2013 : As mentionned by @Ilari Kajaste in comment, this way send you back to the mobile client.
To report a misplaced portal location, you'll have to go to this portal (or get a key of it) and :
click on the portal photo.
Then, click on the EDIT button
Select EDIT TITLE, ADD/EDIT DESCRIPTION or EDIT LOCATION
Enter the correct title or description, or when editing location, touch and drag the map until the marker is in the correct location.
Touch SEND to confirm your correction.
Wait for Niantic to make a decision about your suggestion.
You can open the portal screen, and click the triangle with the exclamation mark in it.
You then have a choice as to what you want to report. Be aware that it can take some time for Niantic to actually update the portal.
(And I mean a really long time)
