Portugal - January 4th, 2012

This wide-swath ASAR image shows the southwestern coast of Portugal. Visible on the left side of the image is the lower course of the Tagus River, the longest river on the Iberian Peninsula. It empties into the Atlantic Ocean near Lisbon, after flowing across both Spain and Portugal. It drains an area of 80,100 square kilometers (30,927 sq mi) (the second largest in the Iberian peninsula after the Douro).

Sediments in Tagus Estuary, Portugal

Portugal - December 29th, 2011

The Tagus River is the longest river on the Iberian Peninsula. It is 1,038 km (645 mi) long, 716 km (445 mi) in Spain, 47 km (29 mi) along the border between Portugal and Spain and 275 km (171 mi) in Portugal, where it empties into the Atlantic Ocean at Lisbon. There, it widens to a large estuary, on which the port city of Lisbon is situated (the city can be observed upon opening the full image). The estuary appears filled with brown sediment near the image center.

The Tagus drains an area of 80,100 square kilometers (30,927 sq mi) (the second largest drainage area on the Iberian peninsula after that of the Douro River). The Tagus is highly utilized for most of its course. Several dams and diversions supply drinking water to most of central Spain, including Madrid, and Portugal, while dozens of hydroelectric stations create power. Between dams it follows a very constricted course, but after Almourol it enters a vast alluvial valley prone to flooding.

Iberian Peninsula from Tagus Estuary to Gibraltar to Pyrenees – July 4th, 2011

Spain - June 21st, 2011

This image stretches across the Iberian Peninsula, located in the extreme southwest of Europe, which includes the modern-day sovereign states of Spain (occupying the majority of the image), Portugal (by the west coast) and Andorra, as well as the British Overseas Territory of Gibraltar.

The Pyrenees form the northeast edge of the peninsula, separating it from the rest of Europe. Part of France can be seen north of these mountains in the upper right corner.

In the south, the peninsula approaches the northern coast of Africa. Part of the Strait of Gibraltar can be seen here, between the two continents, although Gibraltar itself is obscured by clouds.

Of interest on the west coast is the city of Lisbon, in Portugal, on the estuary of the Tagus River (both best observed in the full image).

Portugal - June 6th, 2010

Portugal is located on the west coast of the Iberian Peninsula, in southwestern Europe. Portugal has an area of 35,556 sq mi (92,090 sq km) and a population (2009 est.) of about 10,639,000.

The capital is Lisbon, visible here on the shores of the Tagus River estuary by the lower left edge. Portugal is divided roughly in half by the Tagus River; the highlands rise mostly north of the Tagus and stretch northeast into Spain.

Portugal - December 13th, 2009

The Tagus River appears as a black line crossing southwestern Portugal in this orthorectified image. It empties into the Tagus River Estuary and then the Atlantic Ocean by the city of Lisbon.

Upon opening the full image, the 25th of April Bridge (Ponte 25 de Abril) can be seen as a thick white line over the Tagus, connecting Lisbon to the city of Almada.

Moving northward, in the upper left quadrant, are the mountains of the Serras de Aire e Candeeiros Natural Park. It is one of the 30 areas which are officially under protection in the country.
