What are the effects of the angle between images setting in circular missions when it comes to 3D reconstruction?
Topographic Lidar Data Employed to Map, Preserve U.S. History
In August 2015, the National Park Service (NPS) contracted Woolpert for the Little Bighorn National Monument Mapping Project to record the locations of thousands of headstone markers at the Custer National Cemetery as well as hundreds of battlefield markers at the Little Bighorn National Monument site, which covers approximately 5.5 square miles.
Saharan Sand Blows Across the North African Coast
Plumes of sand from North African deserts are easily visible in this satellite image captured by the Moderate Resolution Imaging Spectroradiometer on NASA's Aqua satellite in late February 2015. The microscopic particles amass and begin a trans-Atlantic journey to South America.
SPOT 5 Captures Images of EU Capital
Released last week as part of the European Space Agency's Earth from Space video series, this false-color image of Brussels was acquired by the SPOT 5 satellite on Sept. 28, 2011, showcasing the central area of Belgium's capital city.

New Land Forms on the Louisiana Coast
A pair of false-color Landsat satellite images of the Wax Lake Outlet in Louisiana shows the spread of mud deposits and land rising out of the water between 1984 and 2014.
Fierce Fortifications Visible on the Iraq-Iran Border
Astronauts using a digital camera aboard the International Space Station took this image of a fortified border between Iraq and Iran.
Looking at a Landslide in India in 3D
A Landsat 8 image of landslide debris blocking the Tsarap River in the Indian states of Jammu and Kashmir is helping authorities assess a dangerous situation, as they're concerned an earthen dam will break and lead to damaging flooding downstream.
Austfonna Ice Cap Sheds Ice
During the last two decades, the Austfonna ice cap on Norway's Nordaustlandet island in the Svalbard archipelago has lost more than 50 meters of ice and stretched 50 kilometers inland. The outlet glacier from the ice cap is now flowing 25 times faster in that same time period.
Astronauts Image Florida at Night
The Florida peninsula is easily recognizable from space, even at night, in this image taken from the International Space Station in October 2014. Gauging the size and intensity of lights gives an intuitive sense of city size and population.
