Digital Elevation Model Visualization of the Volcanoes of Indonesia

E-mail Print PDF

Gede-Pangrango

In this article, I'd like to provide some visualization of some of the well-known volcanoes in Indonesia using Intermap's Digital Elevation Model derived from its proprietary IFSAR technology. These visualizations were made using GlobalMapper v11 (shaded reliefs) and 3DEM v20.7 (rotating movie). Included here are the following volcanoes: Tangkuban Perahu Volcano (West Java), Merapi Volcano (Central Java), and Mount Batur (Bali). More volcanoes will be added soon.

These shaded relief images conveys the perception of depth by employing shading effects. For visual appeal, color shader is also involved, with gradation from dark green for low elevation areas, to yellow for medium elevation, and dull brown for high elevation. Based from the shaded relief, people will be able to interpret prominent terrain features such as craters, valleys and ridges, outcrops, lava flows, faults, flood plains, and so on. A more compelling visualization is the 3D perspective, which further emphasizes the perception of depth.

If you are interested to Intermap's Digital Elevation Model dataset represented here, or perhaps you'd like to know more about the NEXTMap Indonesia dataset, feel free to contact me.

1. Tangkuban Perahu, West Java

This wonderful volcano is known for its huge craters, which allows visitors to climb up to the rim of the crater. Tangkuban Perahu means "upturned boat" in local's language. Located just less than 30 km north of the city of Bandung. This volcano is still active, it was last erupted in 1983.

2. Mount Merapi, Central Java

Merapi volcano is one of the most active volcanoes in the world. Its characteristic pyroclastic materials in the form of nuee ardantee is very well-known to local people. This volcano has continually spewed ash and pyroclastic flows since 1548, with its latest eruption in 2006, shortly before tectonic earthquake that struck the city of Yogyakarta, which is located about 30 km south of the volcano.

3. Mount Batur, Bali

Mount Batur (Gunung Batur) is an active volcano located at the center of two concentric calderas  north west of Mount Agung, Bali, Indonesia. The south east side of the larger 10×13 km caldera contains a caldera lake. The inner 7.5-kilometer-wide caldera, which was formed during emplacement of the Bali (or Ubud) ignimbrite, has been dated at about 23,670 and 28,500 years ago.

The SE wall of the inner caldera lies beneath Lake Batur; Batur cone has been constructed within the inner caldera to a height above the outer caldera rim. The Batur stratovolcano has produced vents over much of the inner caldera, but a NE-SW fissure system has localized the Batur I, II, and III craters along the summit ridge. Historical eruptions have been characterized by mild-to-moderate explosive activity sometimes accompanied by lava emission. Basaltic lava flows from both summit and flank vents have reached the caldera floor and the shores of Lake Batur in historical time. The caldera contains an active, 700-metre-tall stratovolcano rising above the surface of Lake Batur. The first historically documented eruption of Batur was in 1804, and it has been frequently active since then.

The caldera is populated and includes the two main villages of Kedisan and Toya Bungkah. The locals largely rely on agriculture for income but tourism has become increasingly popular due to the relatively straightforward trek to the summit of the central crater. The lake, Danau Batur, is the largest crater lake on the island of Bali and is a good source of fish.
