Both of those are in the same cell. What does the nomination map look like when you go to begin a submission with the toggle on while you are standing there? It should show you if the Wayspots have been removed or if there is another one in the cell that I don’t see on this old map.
(The pickleball court straddles two L17 cells, but both are occupied.)
From the look of this, then NO those wayspots cannot be moved to become pokestops. They are in legitimate locations and there are no locations which are better than where they are currently.
It is only correct to move a wayspot when it is either in an incorrect location OR when it is in an OK location but there is a better one available.
Examples of the latter: a wayspot in the middle of a football pitch would be better at the edge. None of these meet this condition.
It shouldn’t been removed then cause there’s nothing wrong with the location. The Volleyball court was accidentally put in the wrong location by a few feet same has the pickleball court
