摘要 打破了纠偏数据文件检索的传统思维定势,创新性地提出了一种基于2进制文件的预处理和偏差定位方法,将纠偏的执行效率提高了11%,存储空间至少节省了50%. A brand new idea for fixing the biased coordinates in China was proposed. A correction method of pre-processing storage data and fast navigating to the exact position according to original location's offset is introduced to save at least 11 persent of execution time and 50 persent of storage space.
