In practice, the selected interval thickness is usually a compromise between the need for a thin interval to maximize the resolution and a thick interval to minimize the error.
为保证最大分辨率必须选用薄层，为使误差最小却须选用厚层，实际上通常选择介于两者之间的最佳厚度。

The longitudinal resolution and alias at off-isocenter locations are related to factors of distance from the isocenter, interpolation algorithm, reconstruction interval and pitch.
纵向分辨率和混淆失真与偏离成像中心的距离、插值算法、重建间隔和螺距等因素有关。

The accuracy of flood area is mostly dependent on the contour interval of map, accuracy of digitizing map, accuracy of DEM, and interval of GRID, detecting resolution of pixels.
