Specifically, the data storage management submodule is mainly used for data storage, and the data storage is a process of inputting original geographic information data into a database according to a designed storage model. And inputting the data into different databases according to different sources of the original geographic information data. The data storage adopts the idea facing to the entity to organize and manage, therefore, facing to global mass data, a reasonable data storage rule needs to be established to meet the requirements of high-efficiency management and application of mass data, and the system storage mode is as follows: batch import, individual data import, and database import.
The data types in the database system are generally divided into four categories: vector data, raster data, metadata, and professional data. In order to realize the life cycle management of data and ensure that the volume of a database body does not increase along with the increase of the managed data volume, various data are reasonably organized and stored.
Vector data is small in data quantity, high in use frequency and high in auxiliary query and retrieval requirements, and is stored mainly in a library body mode. The vector data storage mode is that vector data is logically organized according to classification and layers and is divided into three basic types of points, lines and surfaces according to types, the vector data is classified along with the layering, only one data type can be stored in each layer, and the vector data is physically stored according to a database and table by adopting a database mode.
The raster data mainly comprises data such as images, digital Elevation Models (DEMs), live-action three-dimensional models and the like, and the data volume is generally large, so that the raster data is mainly stored in a system file mode, and when the data volume is small, the raster data can be directly stored in a database mode in a frame and block mode and managed in a unified database mode. The raster data storage model is a remote sensing image data storage model that includes elements such as pixels (or pixels), raster blocks, bands (or layers), and metadata from an object-oriented viewpoint. The grid kernel data is a multi-dimensional matrix composed of pixels, the matrix has multiple dimensions, coordinates on a two-dimensional plane are represented by (X, Y), and the third dimension can be elevation, time or spectral information. The pel depth represents the data size of each pel, and the depths of all pels in the multi-dimensional matrix are the same. The core data needs to be chunked to optimize storage and retrieval functions. Each grid block will be stored in the grid block in the form of a blob, each row of records in the table can only store one grid block, and the user is allowed to customize the block size. Along the boundary blocks in the positive direction of each dimension, if not all of the blocks are of the same size, they are complemented by a padding pel, whose value is 0, to ensure that all blocks are of the same size. The padded boundary blocks have the same pel depth as the unfilled blocks, and thus all blocks have the same size.
Metadata usually exists in various data products, the data volume is not good and quantized, and the metadata is managed in a library mode according to the requirement of integrated storage management of the data products and the storage mode of the data products described by the metadata. The metadata storage mode is that because the types of raster data supported by the comprehensive database are various, after the data is imported into the database, it is difficult to distinguish what type of data is before the data is put into the database. Based on the uniform storage mode adopted by the spatial database engine for any type of raster data, some information useful for users may be lost after the data is put in storage, so that it is necessary to establish corresponding metadata tables for different data types. The information that needs to be stored in the metadata table varies from one type of raster data to another. The metadata table is essentially a database common service table, and corresponding fields are designed according to different data types to store various information of images. After the grid data are put into a warehouse, inserting a record into a corresponding grid metadata table according to the type of the data; accordingly, if a raster data is deleted, it is necessary to delete not only various tables storing data information in the database but also corresponding records in the corresponding raster metadata table. The metadata table fields in the raster metadata table include a storage raster data type, a storage raster list, a storage raster data name, a minimum longitude value of a storage image range, a minimum latitude value of a storage image range, a maximum longitude value of a storage image range, a maximum latitude value of a storage image range, a start time of a storage data scan, an end time of a storage data scan, and the like.
Professional data mainly comprises structured professional data and unstructured professional data. Most of the structured professional data are small in data size and are stored in a library mode generally; unstructured professional data, such as knowledge data, theoretical research data, audio, video and the like, are generally large in data volume, and can be stored in a file system mode or a library mode, and the two storage modes are managed in a library mode. When data files are stored in a file system, tree directory storage management can be established according to certain directory naming rules and name naming rules and according to data classification, data acquisition time and other information, for example, a main directory is a measured area name, subdirectories are partition numbers, a figure number subdirectory is established under the tree directory, and corresponding layer files and metadata files are stored under the figure number directory.
Before data is put into a warehouse, the data is checked, and the integrity of the data is mainly checked. Checking whether the coverage range of the geographic data is complete and is not omitted; checking whether various geographic elements are complete or not without omission or redundant and repeated phenomena; checking whether the layering of the ground feature elements is correct without the phenomena of missing layers or redundant layers and repeated layers; checking whether the names and the notes are correct and complete without missing, redundant or repeated phenomena.
In addition, the data management and access modes of the database are divided into two main categories: the method comprises the steps that vector data and raster data are organized, managed and accessed through a spatial data engine; and secondly, metadata and professional data are matched with each other through database management software and a distributed file system to finish organization, management and access of the data. The method is characterized in that the image data volume is huge, so that the problem that efficient access of image data is always a key link for realizing the spatial database technology is solved, and the comprehensive information database is designed by adjusting the size of a data block, establishing a pyramid, a spatial data index and the like, so that an efficient data access mechanism is realized.

Specifically, the single data entry is to import various types of existing vector data, raster data, unstructured data, text data, multimedia data, and other data.

Grid data: batch import of images, DEMs, oblique photography models and the like is realized. Text data: batch import of data such as knowledge data and theoretical research data of text documents stored in a text format is realized. Multimedia data: audio, video, and the like data, and compressed packets, and the like data. Importing system exchange format data: the process data exchange format or the result data exchange format data defined by the system is imported, so that the system engineering migration is facilitated.
