Using latitude and longitude is easiest along the equator, where the grid lines formed are roughly square.

沿着赤道使用维度和经度相当简单，形成的网格线大致也是方形的。

We have achieved the parallelization by extracting the analysis boxes and model grid point latitude rows with leaped step and distributing data to different processors.

该算法通过间隔选取分析盒子和模式格点纬圈行，将数据分配给不同的处理机实现分布式并行。

DEM (Digital elevation Model) is a data set of plane coordinate or longitude, latitude, and elevation of the regular square grid points in some region.

数字高程模型(DEM)是一定区域范围内规则格网点的平面坐标及其高程的数据集或者是经、纬度和海拔高度的数据集。
