An improved distributed storage and query for remote sensing data
ذخیره سازی توزیع شده بهبود یافته و پرس و جو برای داده های حسی راه دور-2018 With the rapid development of information technology, the amount of remote sensing data is increasing at an unprecedented scale.
In the presence of massive remote sensing data, the traditional processing methods have the problems of low efficiency and lack of
scalability, so this paper uses open source big data technology to improve it. Firstly, the storage model of remote sensing image data
is designed by using the distributed storage database HBase. Then, the grid index and the Hibert curve are combined to establish the
index for the image data. Finally, the method of MapReduce parallel processing is used to write and query remote sensing images.
The experimental results show that the method can effectively improve the data writing and query speed, and has good scalability.
