New Zealand - December 22nd, 2011

This orthorectified image shows the Great Barrier Island, a large island of New Zealand, situated 100 km to the north-east of central Auckland in the outer Hauraki Gulf. With an area of 285 km2 it is the fourth-largest island of New Zealand’s main chain of islands, with its highest point, Mount Hobson, rising 621 m.

South of the island is the Colville Channel, one of three channels connecting the Hauraki Gulf with the Pacific Ocean to the northeast of Auckland, New Zealand. It lies between the southern end of Great Barrier Island and Cape Colville at the northern tip of the Coromandel Peninsula. The tiny Channel Island lies in the centre of the channel.

The Coromandel Peninsula (visible in the lower part of the full image) lies in the North Island of New Zealand. It is part of the Waikato Region and Thames-Coromandel District and extends 85 kilometres north from the western end of the Bay of Plenty, forming a natural barrier to protect the Hauraki Gulf and the Firth of Thames in the west from the Pacific Ocean to the east. At its broadest point, it is 40 kilometres wide.

The Auckland metropolitan area on New Zealand‘s North Island, visible in this orthorectified image as an extensive white area, is the largest and most populous urban area in the country. Its population is approaching 1.4 million residents, 31 percent of the population of New Zealand.

Auckland lies between the Hauraki Gulf of the Pacific Ocean to the east, the low Hunua Ranges to the south-east, the Manukau Harbour to the south-west, and the Waitakere Ranges and smaller ranges to the west and north-west. The central part of the urban area occupies a narrow isthmus between the Manukau Harbour on the Tasman Sea and the Waitemata Harbour on the Pacific Ocean. It is one of the few cities in the world to have harbours on two separate major bodies of water.

Auckland also straddles the Auckland Volcanic Field, which has produced approximately 50 volcanoes. These take the form of cones, lakes, lagoons, islands and depressions, and several have produced extensive lava flows. Most of the cones have been partly or completely quarried away. The individual volcanoes are all considered extinct, although the volcanic field itself is merely dormant.

The Coromandel Peninsula lies in the North Island of New Zealand. It is part of the Waikato region and extends 85 kilometres north from the western end of the Bay of Plenty, forming a natural barrier to protect the Hauraki Gulf and the Firth of Thames in the west from the Pacific Ocean to the east.

At its broadest point, the peninsula is 40 kilometres wide. It is steep and hilly, as the Coromandel Range forms a spine for the peninsula rising to nearly 900 metres. The contours of these mountains can be seen clearly in this orthorectified image.

By contrast, a flat area can be seen at the foot of the peninsula. This area is known as the Hauraki Plains, occupying the southern portion of a rift valley.

The Firth of Thames, visible in its entirety upon opening the full version of this orthorectified image, is a large bay located in the north of the North Island of New Zealand.

The firth lies at the southern end of the Hauraki Gulf, southeast of the city of Auckland. It occupies a rift valley or graben between the hilly Coromandel Peninsula (right) and Hunua Ranges which continue into the Hauraki Plains to the south. The large, dark patch below the firth is an area of native forest.

It is the firth of the rivers Waihou and Piako, the former of which was formerly named the Thames River. The Waihou River can be seen running parallel to the mountains on the right and empyting into the bay.
