Problems solved by technology
[0003] However, the traditional relational data model and data organization structure only realize the integrity of data organization at the conceptual and logical levels, including the sequence snapshot model, the base map correction model, the geographic-time composite model, and the geographic-time cube model, etc. The access weight of remote sensing image data is not considered, and disk storage is uniformly used for physical implementation, resulting in disk I / O becoming the bottleneck of database scheduling performance, which greatly increases disk I / O load and data scheduling time

Embodiment Construction
[0022] The present invention will be described in detail below with reference to the drawings and examples.
[0023] Such as figure 1 Shown, the information storage management method based on MongoDB of the present invention, concrete steps are as follows:
[0024] Step 1, the remote sensing image storage system requests the resource satellite center for metadata application request query results according to the application record information of the resource satellite center;
[0025] Step 2, the remote sensing image storage system requests the query result according to the metadata request, and requests the MongoDB database to return the geographic location of the thumbnail;
[0026] Step 3, the remote sensing image storage system judges the storage status of the geographic location of the thumbnail and updates it.
[0027] In the first step, the remote sensing image storage system sends an application request to the resource satellite center according to the application r...

The MongoDB-based information storage management method provided by the invention comprises the following specific steps that: step 1, a remote sensing image storage system requests a metadata application request query result from a resource satellite center according to application record information of the resource satellite center; 2, the remote sensing image storage system requests a query result according to the metadata application request, and requests a MongoDB database to return to the geographic position of the thumbnail; and 3, the remote sensing image storage system judges the geographic position storage state of the thumbnail and updates the geographic position storage state. According to the method, the throughput pressure of the server-side disk under the concurrent environment of the remote sensing image storage system can be reduced, and the scheduling and drawing efficiency of the remote sensing image storage system can be ensured.
Description
technical field [0001] The invention relates to the technical field of remote sensing image data storage management methods, in particular to a MongoDB-based information storage management method. Background technique [0002] The use of remote sensing data and fusion technology for monitoring, early warning and analysis of the region is of great significance for formulating specific disaster prevention programs and taking effective prevention and control measures. How to effectively manage the multi-temporal and refined historical data of massive topography and geomorphology in the region, as well as the latest data obtained in real time by aerial remote sensing and satellite remote sensing technology, support efficient storage and dispatching, and meet the scientific decision-making and application needs of emergency relief. It has become a difficult point in data management of remote sensing image geographic information database. The access to remote sensing image data a...
