Remote sensing image compression storage method and system based on road traffic network data

The invention relates to a remote sensing image compression storage method and system based on road traffic network data, and the method is characterized in that the method comprises the following steps: S1, a road traffic network data definition and preprocessing step, which is used for collecting and sorting the road traffic network data in a to-be-compressed remote sensing image; s2, a road traffic network and remote sensing image multi-layer superposition step, which is used for constructing a multi-layer map in GIS software and performing multi-layer superposition; s3, irregular blocking of a remote sensing image area: blocking the original remote sensing image according to the collected and arranged road traffic data and water system data; s4, performing heterogeneous compression storage on the remote sensing image, namely performing compression storage on the divided three parts of remote sensing image by adopting different storage modes; and S5, a remote sensing image decompression step for decompress
