https://www.aireparkreservation.com/aires-camping-cars/nouvelle-aquitaine/deux-sevres/niort-la-roussille indicates a caravan_site with power_supply at this location but after studying mapillary images I agree that there are no services here. In fact there is a motorhome on Mapillary but there are no signs or markings indicating a caravan_site. I am not sure this should be marked as a caravan_site at all. But I updated it to reflect that there are no services.
