| 摘 要： | 随着遥感和测绘技术的进步,日益增大的数据量和高效的数据I/O矛盾逐渐凸显。本文针对这个问题提出了地理栅格数据的一种并行I/O模式,并对该I/O模式进行了相应的编程实现。通过设计实验验证其正确性和效率,我们发现相比传统的栅格数据I/O库（GDAL库）而言,采用本文提出的并行I/O模式对应的I/O库将能同时保证结果的正确性和高效性。

| Abstract: | With the development of Remote Sense and Surveying and Mapping Technology, contradiction between the increasing data and effective data I/0 is becoming an important issue. A parallel I/0 mode answering this issue for geospatial raster data is put forward and implanted here in this paper. Compared with the traditional I/0 library-- GDAL, the parallel I/0 library that adopted the new mode makes the parallel I/0 both correct and efficient. |
