Researchers at the University of Copenhagen analyzed old aerial photos to better understand mechanisms behind Antarctic ice shelf collapse. The study reveals that rising sea temperatures are a primary driver of collapse, contradicting previous assumptions.
A Northwestern University and University of Copenhagen study reveals that Greenland's thousands of peripheral glaciers have rapidly retreated over the past two decades. The research team combined satellite images with historical aerial photographs to document changes in over 1,000 glaciers over a century.
A team of researchers developed a new technique using drone photographs to estimate the age-structure of free-ranging dolphin groups, aiding in timely conservation efforts. By analyzing the distance between a dolphin's blowhole and dorsal fin, they can infer its total body length and age.
A long-term study at the University of Eastern Finland reveals a significant reduction in palsa area by over 75% from 1959 to 2021. Climate change has only a limited impact on active layer thickness, contradicting expectations.
Researchers have discovered that reef halos, visible from satellite imagery, can provide insights into coral reef health globally. These bands of bare seafloor surrounding coral patch reefs are more common and dynamic than expected, with the potential to serve as a window into reef health.
Researchers in Brazil developed a computer program that locates swimming pools and rooftop water tanks in aerial photographs, using artificial intelligence to identify socio-economically deprived urban areas at risk for diseases transmitted by Aedes aegypti. The innovation can be used as a public policy tool for dynamic socio-economic ...
The discovery of 66 new Roman Army sites has provided more insights into the Roman Empire's military presence in the Iberian Peninsula. The analysis of these camps reveals a larger Roman army presence than previously thought during the 200-year battle to conquer the region.
Researchers at Ben-Gurion University have developed a new satellite imaging system that can capture high-quality images using smaller nanosatellites, reducing costs and time required for space-based telescopes.
Researchers used drones to take aerial photographs of leopard seals, finding they can accurately estimate body size and mass. This non-invasive method could be used to assess body condition in other pinnipeds, tracking responses to environmental changes and managing marine ecosystems.
A Johns Hopkins team discovered three ways to send rogue commands to interfere with an airborne hobby drone's operation, causing it to land or crash. The finding highlights the vulnerability of drones to hackers, which is crucial for tasks like aerial deliveries and photography.
A USDA aerial photography survey found that the invasive leafy spurge weed is displacing native mountain big sagebrush seedlings in Idaho. The survey used high-resolution digital cameras to sample large areas of the western US.
A PhD student at the University of Leeds has developed a predictive model that accurately maps plant communities over large areas using aerial photographs and data from maps. The method achieved an accuracy of up to 92%, comparable to traditional on-site surveys conducted by trained ecologists.
Most Alaskan glaciers are retreating and thinning, especially at lower elevations, while some are advancing, according to a comprehensive USGS study. The report uses satellite images and aerial photographs to document glacier behavior and distribution.
The Citipix Collection, valued at over $14.3 million, is a historic snapshot of urban history in the US at the turn of the century. The collection consists of 500,000 color-stereo images taken between 1999-2002, providing clear detail up to six inches off the ground.
