Indonesia - January 4th, 2012

This orthorectified wide-swath ASAR image shows some of the 272 islands of the Natuna Islands archipelago, located in the Natuna Sea (a section of the South China Sea) in the larger Tudjuh Archipelago, off the northwest coast of Borneo. The islands are administratively part of the Riau Islands province of Indonesia.

The Natuna islands are divided into three groups: North Natuna, which includes Laut Island (Pulau Laut); Middle Natuna, which includes Natuna Besar; and South Natuna, which includes Subi Besar.  This image focuses on Natuna Besar (or Great Natuna), the main island of the Natuna Besar Archipelago, as well as the Natuna Islands.

Indonesia - January 4th, 2012

This APM image shows several volcanoes on the island of Java, Indonesia. Visible near the bottom edge is Mount Sumbing or Gunung Sumbing, an active stratovolcano in Central Java, Indonesia, symmetrical with Sundoro. The only report of historical eruptions is from 1730. It has created a small phreatic crater at the summit.

Moving to the northwest of Mount Sumbing one comes to  Mount Gede, followed by the Dieng Volcanic Complex. The complex of volcanoes is located on the Dieng Plateau in the Central Java, Indonesia. The volcanic complex consists of two or more of stratovolcanoes, more than 20 small craters and Pleistocene-to-Holocene age volcanic cones.The Prahu stratovolcano was truncated by a large Pleistocene caldera and then filled by parasitic cones, lava domes and craters.

Surabaya on the Shores of East Java, Indonesia – February 27th, 2012

Indonesia - February 6th, 2012

Visible on the coast of Java as a white area in this orthorectified wide-swath ASAR image is Surabaya, Indonesia’s second-largest city with a population of over 2.7 million (5.6 million in the metropolitan area). It is the capital of the province of East Java. It is located on the northern shore of eastern Java at the mouth of the Mas River and along the edge of the Madura Strait.

Java is almost entirely of volcanic origin; it contains thirty-eight mountains forming an east-west spine which have at one time or another been active volcanoes. Several of these can be seen in a row down the center of the island, although Surabaya lies along the coastal plain. More mountains and highlands help to split the interior into a series of relatively isolated regions.

Indonesia - January 7th, 2012

This APM image shows the city of Semarang, located on the northern coast of Java, Indonesia. The capital of the province of Central Java, it has an area of 305.17 km². The northern part of the city is built on the coastal plain while the southern parts are on higher ground.

Visible to the south of the city are numerous volcanic peaks. Four stratovolcanoes can be observed in a curved line due south of Semarang: (from top to bottom) the deeply eroded Mount Ungaran, Mount Telomoyo, the dormant Mount Merbabu and the active Mount Merapi. In the lower left quadrant are two active stratovolanoces: Mount Sundoro (left) and Mount Sumbing (right).

Vegetation Index of Borneo, Belintung and Java, Indonesia

6.9S 107.6E

February 18th, 2012 Category: Vegetation Index

Indonesia - January 4th, 2012

This FAPAR image shows the vegetation index of Kalimantan (the Indonesian part of the island of Borneo, above), Belintung (also part of Indonesia, near the left edge), and Java (another island of Indonesia, below). The index range from good (green) to high (rusty red) on all three islands, with very few areas of low (yellow) activity.

Belintung is a medium sized island of about 3,000 square miles (7,800 km2), it consists of moderately rugged terrain with several hills. Java is almost entirely of volcanic origin; it contains thirty-eight mountains forming an east-west spine. More mountains and highlands help to split the interior into a series of relatively isolated regions suitable for wet-rice cultivation.
