The constant is based on the diameter of the Earth and the equations Microsoft used to set the zoom levels. At any latitude and zoom level, you can determine the scale by using the following equation: Map resolution = 156543.04 meters/pixel * cos(latitude) / (2 ^ zoomlevel) Remember ...
The fine-scale seismic features near the inner core boundary (ICB) provide critical insights into the thermal, chemical, and geodynamical interactions between liquid and solid cores, and may shed light on the evolution mechanism of the Earth’s core. Her
Rougher surfaces will have a greater surface area to planar area ratio, and perfectly smooth surfaces will have a value of 1. This is a 3D analog to the classical “chain-and-tape” method, which calculates roughness as the ratio of the contoured distance (chain length) and linear distance...
The seismological properties of Earth’s inner core are key to understanding its composition, dynamics and growth history. Within the inner core, fine-scale heterogeneity has previously been identified from backscattering of high-frequency compressional waves. Here we use historical earthquake and explosio...
We prepared a dataset comprising 4069 historical landslide locations and 11 conditioning factors (altitude, slope degree, profile curvature, distance to river, aspect, plan curvature, distance to road, distance to fault, rainfall, geology and land-sue) to construct a geospatial database and divided...
(And the nearest major galaxy,Andromeda, is—if scaled—about 13.4× the Earth-sun distance, so between the Saturn-sun and Uranus-sun distances. Really, a very very very big playground!) To understand the vastness of space, it really helps to comprehend the emptiness. Even the asteroid belt...
The ability to detect the Earth's magnetic field and use it to compute direction or spatial position. Utilizing magnetosensation for navigation purposes has been described in many animals, including some rodents and bats. Egocentric coordinates Coordinates that are given relative to the body axis; ...
The Sun’s activity cycle governs the radiation, particle and magnetic flux in the heliosphere creating hazardous space weather. Decadal-scale variations define space climate and force the Earth’s atmosphere. However, predicting the solar cycle is challenging. Current understanding indicates a short wi...
al.2014). The MSTIDs mostly propagate against the modeled horizontal wind. This confirms that the observed MSTIDs were primarily due to GWs because the atmospheric winds pose a directional filter. This filter favors GWs propagating against the winds to reach ionospheric heights (Sun et al.2007)...
in Hutiaoxia town (Xiatiaotou) in Shangri-La, it is revealed that the stable sequences including Paleozoic and Mesozoic Triassic strata of Yangtze craton are thrust nappes, overlying westward on the strata sequences of the Tibetan-Sanjiang orogenic system, with the thrusting distance over 50 km...
