I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
A misaligned pano (the aircraft moved some 55 metres between first and last shot). But ok to illustrate a location on the edge of a HIRTA and close to a beacon.
From the launch point you can see the city of Portsmouth, the top of Portsdown Hill and the land running north toward Petersfield, and, depending on time of day and thus height of sun, see clearly toward Southampton or Bognor. Good place for night shots of Portsmouth.
The launch site I chose was down the slope away from the car park, Be careful of the picnic tables, they contain a lot of metal, stay 10 metre away if you don't want to recalibrate you compass.
The car park is home to the justly famous Mick's Monster Burgers, open 24/7. The location is a very poular meeting place for car and motorbike clubs as well as the general public
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 21/09/2020. It remains the responsibility of any pilot to check for any changes before flying at the same location.
