the proportion that a representation of an object bears to the object itself: a model on a scale of one inch to one foot. the ratio of distances or sometimes of areas on a map to the corresponding values on the earth. a certain relative or proportionate size or extent: ...
Thanks to such second- and third-generation sensor systems as Thematic Mapper, SPOT, and AVHRR, a user of digital satellite imagery for remote sensing of the earth's surface now has a choice of image scales ranging from 10 m to 1 km. The choice of an appropriate scale, or spatial resolu...
Scale is a key concept for understanding the complexity of earth system.And it is regarded as one of the main challenges of earth observation.It is crucial to select the optimal spatial resolution of remote sensing image according to its application field and its characteristics.Based on analyzing...

Present-day people from England and Wales have more ancestry derived from early European farmers (EEF) than did people of the Early Bronze Age1. To understand this, here we generated genome-wide data from 793 individuals, increasing data from the Mi
Projected down to the surface of the Earth's core, we found these variations to be small below the Pacific Ocean, and large at polar latitudes and in a region centred below southern Africa. The flow pattern at the surface of the core that we calculate to account for these changes is ...
