Police have released helicopter footage of the area where they have been searching for missing teenager Liam Smith.
The 16-year-old has not been seen since he boarded a bus from Aberdeen heading south-west on November 17.
A large-scale police operation was launched after he was reported missing and specialist teams including divers, dogs and mountain rescue experts have been involved in the search.

Officers have now released a video taken on board a helicopter highlighting the open fields, woodland and waterways across the Crathes area.
Last month Chief Inspector Martin Mackay said: “The terrain we are entering with regard to our searches is extremely challenging – not helped by the current weather – and even our own officers are finding it difficult to navigate certain areas.
“They are trained and experienced to do this though and we will continue to ensure that all the land we need to cover is searched effectively.”
Liam boarded the 202 Stagecoach bus from Aberdeen bus station at 1.11pm on November 17.
He purchased a bus ticket for Raemoir Road in Banchory – around 20 miles away in the Deeside area – and following eyewitness reports, officers believe he alighted the vehicle in Crathes.
The 6ft4in teen was carrying a distinctive camouflage North Face rucksack and was wearing Nike Air Max trainers.
Anyone with information about his whereabouts is asked to contact officers on 101, quoting incident number 1302.
