March 10th, 2012 Category: Rivers

Canada - December 31st, 2011

The Ottawa River flows across the middle of this image of Canada, between the cities of Ottawa and Gatineau. The cities appear as bright white areas. The geographically larger Ottawa is situated on the southern banks of the river, while Gatineau is located by the northern banks.

The image is  orthorectified, showing hillier terrain dotted with lakes to the north of the river, and mostly flat terrain to the south. In the full image, numerous fields can be observed in the lower half of the image.

Pontianak by Kapuas River Delta, Indonesia

Indonesia - January 4th, 2012

Visible as a small white area near the shores of the island of Borneo is Pontianak, the capital of the Indonesian province of West Kalimantan. It is located almost precisely on the equator, hence it is widely known as Kota Khatulistiwa (Equator City). As can be observed in this orthorectified wide-swath ASAR image, the land near the city is mostly flat, while some hills are visible to the north and northeast.

Pontianak is a medium-size industrial city that occupies an area of 107.82 km² in the delta of the Kapuas River. The Kapuas River  is a river in the Indonesian part of Borneo island, at the geographic center of Maritime Southeast Asia. At 1,143 kilometers (710 mi) in length, it is the longest river of Indonesia and one of the world’s longest island rivers. It originates in the Müller mountain range at the center of the island and flows west into the South China Sea creating an extended marshy delta.

Agriculture Around Lower Mississippi River, USA

32.8N 88.7W

March 3rd, 2012 Category: Rivers

USA - December 29th, 2011

This orthorectified image shows part of the section of the Mississippi River called the Lower Mississippi River. This section runs from its confluence with the Ohio River to its mouth at the Gulf of Mexico. Measured by water volume, the Lower Mississippi’s primary branch is the Ohio River.

The widest point of the Mississippi River is in the Lower Mississippi portion where it exceeds 1 mile (1.6 km) in width in several places. Many rectangular fields can be seen on either side of the river, in the Mississippi River Valley. Formed from thick layers of this river’s silt deposits, the Mississippi River Valley is one of the most fertile agricultural regions of the country.

Osaka by Yodo River and Osaka Bay, Japan – January 13th, 2012

34.6N 135.5E

January 13th, 2012 Category: Image of the day, Rivers

Japan - January 9th, 2012

Situated near the center of this orthorectified wide-swath ASAR image is Osaka, a city in the Kansai region of Japan’s main island of Honshu, the capital city of Osaka Prefecture. Located at the mouth of the Yodo River on Osaka Bay, Osaka is the third largest city by population after Tokyo (special wards) and Yokohama.

The city of Osaka has its west side open to Osaka Bay. It is otherwise completely surrounded by more than ten smaller cities, all of them in Osaka Prefecture, with one exception: the city of Amagasaki, belonging to Hyōgo Prefecture, in the northwest. The city occupies a larger area (about 13%) than any other city or village within Osaka Prefecture. The highest point in Osaka is in Tsurumi-ku at 37.5 metres (123.0 ft), and the lowest point is in Nishiyodogawa-ku at −2.2 metres (−7.2 ft).

Edinburgh by Firth of Forth, Scotland – November 21st, 2011

55.9N 3.1W

November 21st, 2011 Category: Image of the day, Rivers

United Kingdom - November 8th, 2011

This orthorectified image shows the Firth of Forth (lower half of image), the estuary or firth of Scotland’s River Forth, where it flows into the North Sea. It is located between Fife to the north, and West Lothian, the City of Edinburgh and East Lothian to the south. Populated areas appear white in this image.

Geologically, the Firth of Forth is a fjord, formed by the Forth Glacier in the last glacial period. The river is tidal as far inland as Stirling, but generally it is considered that the inland extent of the firth ends at the Kincardine Bridge. The inner Firth, i.e. between the Kincardine and Forth bridges, has lost about half of its former intertidal area as a result of land being reclaimed, partly for agriculture, but mainly for industry and the large ash lagoons built to deposit the spoil from the coal fired Longannet Power Station near Kincardine.
