New Zealand, SRTM Shaded Relief and Colored Height |
| Original Caption Released with Image |
New Zealand straddles the juncture of the Indo-Australian and Pacific tectonic plates, two of Earth's major crustal plates. The two plates generally converge in subduction zones, but in a scissor-like pattern, with the Indo-Austalian plate overriding the Pacific plate to the north and the Pacific plate overriding the Indo-Australian plate to the south. New Zealand is "what happens" in between at and near the cross point of this scissor pattern. Here the convergence has built two major islands that together exhibit very active volcanoes and fault systems, and these geologic features are very evident in the topographic pattern. The North Island lies at the southern end of the west-over-east (Indo-Australian over Pacific) plate convergence. The Pacific plate dives under the North Island and this subduction process leads to melting of rocks at depth, the rise of magma to the surface, and the formation of volcanoes and other geothermal features. Most notable are Mount Taranaki on the west coast, and Mounts Ruapehu, Ngauruhoe, and Tongariro just south of the island's centerpoint, all of which are shown with white peaks in this display. The Rotorua geothermal field occurs further northeast and is evident here as a scattering of comparatively small bumps created by smaller volcanic eruptions. The South Island straddles the cross point of the subduction scissor pattern and prominently features a fault system that connects the two subduction zones. (The east-over-west (Pacific over Indo-Australian) plate convergence generally occurs south of the South Island.) The Alpine fault is the major strand of this fault system along most of the length of the island, near and generally paralleling the west coast. Its impact upon the topography is unmistakable, forming an extremely sharp and straight northwest boundary to New Zealand's tallest mountains, the Southern Alps. Although offsets on the Alpine fault are generally right-lateral (35-40 millimeters per year) and thus consistent with the offset in the subduction zone pattern, vertical offsets (about 7 millimeters per year) are likewise consistent with the uplift of the Southern Alps. Two visualization methods were combined to produce this image: shading and color coding of topographic height. The shade image was derived by computing topographic slope in the northwest-southeast direction, so that northwest slopes appear bright and southeast slopes appear dark. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow and tan, to white at the highest elevations. Elevation data used in this image were acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's, surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Geospatial-Intelligence Agency (NGA) of the U.S. Department of Defense and the German and Italian space agencies.

Australia, Shaded Relief and Colored Height |

Australia is the world's smallest, flattest, and (after Antarctica) driest continent, but at 7.7 million square kilometers (3.0 million square miles) it is also the sixth largest country. Its low average elevation (300 meters, or less than 1000 feet) is caused by its position near the center of a tectonic plate, where there are no volcanic or other geologic forces of the type that raise the topography of other continents. In fact Australia is the only continent without any current volcanic activity at all - the last eruption took place 1400 years ago at Mt. Gambier. The Australian continent is also one of the oldest land masses, with some of its erosion-exposed bedrock age dated at more than 3 billion years. More than one-fifth of the land area is desert, with more than two-thirds being classified as arid or semi-arid and unsuitable for settlement. The coldest regions are in the highlands and tablelands of Tasmania and the Australian Alps at the southeastern corner of the continent, location of Australia's highest point, Mt. Kosciusko (2228 meters, or 7310 feet.) Prominent features of Australia include the Lake Eyre basin, the darker green region visible in the center-right. At 16 meters (52 feet) below sea level this depression is one of the largest inland drainage systems in the world, covering more than 1.3 million square kilometers (500,000 square miles). The mountain range near the east coast is called the Great Dividing Range, forming a watershed between east and west flowing rivers. Erosion has created deep valleys, gorges and waterfalls in this range where rivers tumble over escarpments on their way to the sea. The crescent shaped uniform green region in the south, just left of center, is the Nullarbor Plain, a low-lying limestone plateau which is so flat that the Trans-Australian Railway runs through it in a straight line for more than 483 kilometers (300 miles). Two visualization methods were combined to produce this image: shading and color coding of topographic height. The shade image was derived by computing topographic slope in the northwest-southeast direction, so that northwest slopes appear bright and southeast slopes appear dark. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow and tan, to white at the highest elevations.

Southern Florida, Shaded Relief and Colored Height |

The very low topography of southern Florida is evident in this color-coded shaded relief map generated with data from the Shuttle Radar Topography Mission. The image on the left is a standard view, with the green colors indicating low elevations, rising through yellow and tan, to white at the highest elevations. In this exaggerated view even those highest elevations are only about 60 meters (197 feet) above sea level. For the view on the right, elevations below 5 meters (16 feet) above sea level have been colored dark blue, and lighter blue indicates elevations below 10 meters (33 feet). This is a dramatic demonstration of how Florida's low topography, especially along the coastline, make it especially vulnerable to flooding associated with storm surges. Planners can use data like these to predict which areas are in the most danger and help develop mitigation plans in the event of particular flood events.

SRTM Data Release for Eurasia, Index Map and Colored Height |
| Original Caption Released with Image |
The colored regions of this map show the extent of digital elevation data recently released by the Shuttle Radar Topography Mission (SRTM). This release includes data for most of Europe and Asia plus numerous islands in the Indian and Pacific Oceans. SRTM flew on board the Space Shuttle Endeavour in February 2000 and used an interferometric radar system to map the topography of Earth's landmass between latitudes 56 degrees south and 60 degrees north. The data were processed into geographic "tiles," each of which represents one by one degree of latitude and longitude. A degree of latitude measures 111 kilometers (69 miles) north-south, and a degree of longitude measures 111 kilometers or less east-west, decreasing away from the equator. The data are being released to the public on a continent-by-continent basis. This Eurasia segment includes 5,940 tiles, more than a third of the total data set. Previous releases covered North America and South America. Forthcoming releases will include Africa-Arabia and Australia plus an "Islands" release for those islands not included in the continental releases. Together these data releases constitute the world's first high-resolution, near-global elevation model. The resolution of the publicly released data is three arcseconds (1/1,200 of a degree of latitude and longitude), which is about 90 meters (295 feet). European coverage in the current data release stretches eastward from the British Isles and the Iberian Peninsula in the west, across the Alps and Carpathian Mountains, as well as the Northern European Plain, to the Ural and Caucasus Mountains bordering Asia. The Asian coverage includes a great diversity of landforms, including the Tibetan Plateau, Tarin Basin, Mongolian Plateau, and the mountains surrounding Lake Baikal, the world's deepest lake. Mt. Everest in the Himalayas, at 8,848 meters (29,029 feet) is the world's highest mountain. From India's Deccan Plateau, to Southeast Asia, coastal China, and Korea, various landforms place constraints upon land use planning for a great population. Volcanoes in the East Indies, the Philippines, Japan, and the Kamchatka Peninsula form the western part of the "Ring of Fire" around the Pacific Ocean. Many of these regions were previously very poorly mapped due to persistent cloud cover or the inaccessibility of the terrain. Digital elevation data, such as provided by SRTM, are particularly in high demand by scientists studying earthquakes, volcanism, and erosion patterns for use in mapping and modeling hazards to human habitation. But the shape of Earth's surface affects nearly every natural process and human endeavor that occurs there, so elevation data are used in a wide range of applications. In this index map color-coding is directly related to topographic height, with green at the lower elevations, rising through yellow and tan, to white at the highest elevations. The large, very dark green feature in western Asia is the Caspian Sea, which is below sea, level. Blue areas on the map represent water within the mapped tiles, each of which includes shorelines or islands. Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994.

Mount Ararat, Turkey, Perspective with Landsat Image Overlay |
| Original Caption Released with Image |
This perspective view shows Mount Ararat in easternmost Turkey, which has been the site of several searches for the remains of Noah's Ark. The main peak, known as Great Ararat, is the tallest peak in Turkey, rising to 5165 meters (16,945 feet). This southerly, near horizontal view additionally shows the distinctly conically shaped peak known as "Little Ararat" on the left. Both peaks are volcanoes that are geologically young, but activity during historic times is uncertain. This image was generated from a Landsat satellite image draped over an elevation model produced by the Shuttle Radar Topography Mission (SRTM). The view uses a 1.25-times vertical exaggeration to enhance topographic expression. Natural colors of the scene are enhanced by image processing, inclusion of some infrared reflectance (as green) to highlight the vegetation pattern, and inclusion of shading of the elevation model to further highlight the topographic features. Volcanoes pose hazards for people, the most obvious being the threat of eruption. But other hazards are associated with volcanoes too. In 1840 an earthquake shook the Mount Ararat region, causing an unstable part of mountain's north slope to tumble into and destroy a village. Visualizations of satellite imagery when combined with elevation models can be used to reveal such hazards leading to disaster prevention through improved land use planning. But the hazards of volcanoes are balanced in part by the benefits they provide. Over geologic time volcanic materials break down to form fertile soils. Cultivation of these soils has fostered and sustained civilizations, as has occurred in the Mount Ararat region. Likewise, tall volcanic peaks often catch precipitation, providing a water supply to those civilizations. Mount Ararat hosts an icefield and set of glaciers, as seen here in this late summer scene, that are part of this beneficial natural process Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000.

Elevations vary from about 200 meters (600 feet) in purple shades above sea level in the plains of India to over 7700 meters (25,000 feet) in the Himalayas (white) within this image. Radar data used in this research were acquired by the European Remotes Sensing (ERS) satellites operated by the European Space Agency, which kindly made this data available for research. Research was performed at the Centre for the Observation and Modelling of Earthquakes and Tectonics supported by the U.K. Natural Environment Research Council. Part of this research was performed at the Jet Propulsion Laboratory, California Institute of Technology under contract with the U.S. National Aeronautics and Space Administration. Elevation data used in this image were acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000, and the GTOPO30 data produced by the U.S. Geological Survey Eros Data Center.

The topography rises from the Indus-Ganges plains across the Himalayas and into the lower relief central part of the plateau. The north edge of the plateau is the Altyn Tagh and Kun Lun mountain range. North of Tibet is the Takla Makan desert. Two major faults in western Tibet stand out in the topography and satellite imagery. The Karakoram Fault is the straight line running from top left to lower right across this image, through the Karakoram mountains and southern Tibet. The Altyn Tagh Fault is the slightly curved line running along the northern edge of the plateau from top left to top right. Geologist s and geophysicists have long argued about how fast these two faults in western Tibet are moving. In one model, the Tibetan plateau is like a watermelon seed sliding out to the east along these two faults. In another model, Tibet is deforming internally without sliding rapidly sideways. Scientists at the Centre for Observation and Modelling of Earthquakes and Tectonics and at NASA's Jet Propulsion Lab have used interferometric analysis of radar data from the European Remote Sensing satellites and topographic data from the Shuttle Radar Topography Mission to study the faults in western Tibet. The interferometric analysis was performed with software developed at JPL. The results show that the faults in western Tibet, especially the Karakoram Fault, cannot be moving rapidly. This rules out the watermelon seed "extrusion"http://photojournal.jpl.nasa.gov/catalog/PIA04969 model, at least for western Tibet.

The area known as the Afar Triangle is located at the northern end of the East Africa Rift, where it approaches the southeastern end of the Red Sea and the southwestern end of the Gulf of Aden. The East African Rift, the Red Sea, and the Gulf of Aden are all zones where Earth's crust is pulling apart in a process known as crustal spreading. Their three-way meeting is known as a triple junction, and their spreading creates a triangular topographic depression for which the area was named. Not surprisingly, the topographic effects of crustal spreading are more dramatic in the Afar Triangle than anywhere else upon Earth's landmasses. The spreading is primarily evident as patterns of numerous tension cracks. But some of these cracks provide conduits for magma to rise to the surface to form volcanoes. Shown here are a few of the volcanoes of the Afar Triangle. The larger two are Nabro Volcano (upper right, in Eritrea) and Mallahle Volcano (lower left, in Ethiopia). Nabro Volcano shows clear evidence of multiple episodes of activity that resulted in a crater in a crater in a crater. Many volcanoes in this area are active, including one nearby that last erupted in 1990. This image was created directly from an SRTM elevation model. A shade image was derived by computing topographic slope in the north-south direction. Northern slopes appear bright and southern slopes appear dark. The shade image was then combined with a color coding of topographic height, with green at the lower elevations, rising through yellow, orange, and red, up to purple at the highest elevations. Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000.

The recently active volcano Mt. Manaro is the dominant feature in this shaded relief image of Ambae Island, part of the Vanuatu archipelago located 1400 miles northeast of Sydney, Australia. About 5000 inhabitants, half the island's population, were evacuated in early December from the path of a possible lahar, or mud flow, when the volcano started spewing clouds of steam and toxic gases 10,000 feet into the atmosphere. Last active in 1996, the 1496 meter (4908 ft.) high Hawaiian-style basaltic shield volcano features two lakes within its summit caldera, or crater. The ash and gas plume is actually emerging from a vent at the center of Lake Voui (at left), which was formed approximately 425 years ago after an explosive eruption. Two visualization methods were combined to produce the image: shading and color coding of topographic height. The shade image was derived by computing topographic slope in the northwest-southeast direction, so that northwest slopes appear bright and southeast slopes appear dark. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow and tan, to white at the highest elevations.

Library of Congress Model, Perspective View |

The Shuttle Radar Topography Mission (SRTM) has produced the first high-resolution, near-global elevation dataset of Earth. In recognition of this achievement, and as an illustration of the data, the United States Library of Congress now displays a "solid terrain model" of Los Angeles and adjacent mountainous terrain. The model was created by carving a high-density foam block using computer-guided drills that referenced the SRTM dataset. The block was then covered with a Landsat satellite image using computer-guided paint guns that referenced both the Landsat image and the SRTM dataset. The view shown here mimics the actual model on display at the Library of Congress and was generated from the same satellite image and elevation data sets. The model shows the Pacific Ocean and Santa Monica Mountains along the Malibu Coast (lower left), San Fernando Valley (left center), downtown Los Angeles (bottom center), San Gabriel and Pomona Valleys (lower right), San Gabriel Mountains (right center to far right), and part of the Mojave Desert (upper right). Colors are enhanced true color with added topographic shading, and elevation differences are exaggerated 1.5 times. The view is toward the north-northwest. The Los Angeles region was chosen for the Library of Congress model because it illustrates so many ways that topography affects the daily lives of people. The region consists of a coastal plain, inland valleys, mountains up to 3068 meters (10,064 feet), and a desert interior. Topography blocks the landward influence of marine airmasses here such that summer temperatures often differ by 40 degrees Fahrenheit (22 C) across this region at a given moment even at similar elevations. Temperatures also typically cool with rising elevation, and winter storms drop most of their moisture in the mountains, leaving little rainfall for areas further inland, thus creating the deserts. Topography also controls the land use pattern. The mountains are mostly very rugged, which greatly limits urban expansion. Similarly, major transportation routes are limited to a few mountain passes. Water supply to the city and drainage away from it both follow paths largely dictated by topography. Radio, television, and cell phone transmission towers are all sited with topography in mind to maximize coverage. Its climate and scenic mountain surroundings have been a major part of the appeal of the Los Angeles region as it has grown into one of the world's largest cities over the past 150 years. But the topography that has created this environment also results from and leads to significant natural hazards. The tall mountains result from tectonic compression and uplift of Earth's crust along a kink in the San Andreas fault. (The fault is seen here as a straight boundary between the Mojave Desert and the San Gabriel Mountains.) Major earthquakes occur on the San Andreas fault every few centuries. Damaging earthquakes also occur on other faults across the region several times in a, typical human lifespan. Most of these faults were first recognized by their impact upon the topographic pattern. Meanwhile, wildfires are common in the chaparral covered hills and mountains, and topography affects the fire's path (burning more readily upslope) as well as our ability to fight it. After a fire, rainfall from winter storms often strips exposed soil, accumulates it as mudflows in rugged canyons, and dumps it into the adjacent valleys which are now heavily urbanized. Topography is indeed important in the lives of the people of Los Angeles. Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data substantially help in analyzing Landsat images by revealing the third dimension of Earth's surface, topographic height. The Landsat archive is managed by the U.S. Geological Survey's Eros Data Center (USGS EDC). Elevation data used in this image were acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Geospatial-Intelligence Agency (NGA) of the U.S. Department of Defense (DoD), and the German and Italian space agencies.

Portland, the largest city in Oregon, is located on the Columbia River at the northern end of the Willamette Valley. On clear days, Mount Hood highlights the Cascade Mountains backdrop to the east. The Columbia is the largest river in the American Northwest and is navigable up to and well beyond Portland. It is also the only river to fully cross the Cascade Range, and has carved the Columbia River Gorge, which is seen in the left-central part of this view. A series of dams along the river, at topographically favorable sites, provide substantial hydroelectric power to the region. This perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM), a Landsat satellite image, and a false sky. Topographic expression is vertically exaggerated two times. Landsat has been providing visible and infrared views of the Earth since 1972.

Bali, Shaded Relief and Colored Height |
| Original Caption Released with Image |
The volcanic nature of the island of Bali is evident in this shaded relief image generated with data from the Shuttle Radar Topography Mission (SRTM). Bali, along with several smaller islands, make up one of the 27 Provinces of Indonesia. It lies over a major subduction zone where the Indo-Australian tectonic plate collides with the Sunda plate, creating one of the most volcanically active regions on the planet. The most significant feature on Bali is Gunung Agung, the symmetric, conical mountain at the right-center of the image. This "stratovolcano", 3,148 meters (10,308 feet) high, is held sacred in Balinese culture, and last erupted in 1963 after being dormant and thought inactive for 120 years. This violent event resulted in over 1,000 deaths, and coincided with a purification ceremony called Eka Dasa Rudra, meant to restore the balance between nature and man. This most important Balinese rite is held only once per century, and the almost exact correspondence between the beginning of the ceremony and the eruption is though to have great religious significance. Two visualization methods were combined to produce the image: shading and color coding of topographic height. The shade image was derived by computing topographic slope in the northwest-southeast direction, so that northwest slopes appear bright and southeast slopes appear dark. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow and tan, to white at the highest elevations. Elevation data used in this image were acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994.

This perspective view shows the major volcanic group of Bali, one 13,000 islands comprising the nation of Indonesia. The conical mountain to the left is Gunung Agung, at 3,148 meters (10,308 feet) the highest point on Bali and an object of great significance in Balinese religion and culture. Agung underwent a major eruption in 1963 after more than 100 years of dormancy, resulting in the loss of over 1,000 lives. In the center is the complex structure of Batur volcano, showing a caldera (volcanic crater) left over from a massive catastrophic eruption about 30,000 years ago. Judging from the total volume of the outer crater and the volcano, that once lay above it, approximately 140 cubic kilometers(33.4 cubic miles) of material must have been produced by this eruption, making it one of the largest known volcanic events on Earth. Batur is still active and has erupted at least 22 times since the 1800's. Two visualization methods were combined to produce the image: shading and color coding of topographic height. The shade image was derived by computing topographic slope in the northwest-southeast direction, so that northwest slopes appear bright and southeast slopes appear dark. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow and tan, to white at the highest elevations.
