Abstract
A method of storing remote sensing big data in a Hbase database. The method includes: obtaining a remote sensing image, and pre-cropping the remote sensing image based on a Google S2 algorithm; selecting a grid level based on a resolution of the remote sensing image; demarcating a coverage scope of the remote sensing image; calculating grids covered within the coverage scope; cropping the remote sensing image according to the grids, to yield a plurality of image blocks, and serializing the plurality of image blocks; establishing an Hbase table; establishing a table storage model containing RowKey, and calculating the RowKey according to attributes of an image block; and integrating data structure of multi-source remote sensing image data according to attribute expression of a zoned remote sensing image in a plurality of dimensions, and storing serialized image blocks in an Hbase database according to the RowKey.
