Projections and transformations什么意思
WebEarth Engine的设计使我们在进行计算(computations)时很少需要担心地图投影(map projections)。和尺度(scale)一样，投影(projection)发生于哪一种计算取决于 a "pull" basis(地图缩放水平)。确切地讲，输入(input)投影由输出(output)投影决定。输出的投影又取决于： 函数参数设置(如 crs) WebA projected coordinate system is composed of a geographic coordinate system and a map projection together. A map projection contains the mathematical calculations that convert the angular geodetic coordinates of the GCS to Cartesian coordinates of the planar PCS system.
