Next, an application scenario of the data retrieval method provided in one or more embodiments of the present specification will be described.

In the present specification, a data retrieval method is provided, and the present specification relates to a data retrieval apparatus, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments one by one.
Referring to fig. 1, fig. 1 shows a frame diagram of a data fusion search analysis system according to an embodiment of the present disclosure.
As shown in fig. 1, the data fusion search analysis system is used for fusion search analysis of sky-ground multi-scale space-time data, and the sky-ground multi-source heterogeneous data engine used by the data fusion search analysis system comprises a data access engine, a data storage engine, a data calculation engine and a data update engine. The data fusion retrieval analysis system comprises a data management module, a data retrieval module, a multidimensional data visual superposition analysis module and a task management module. The data management module is used for managing remote sensing data (remote sensing images), video data, meteorological data (meteorological site data), meteorological grid data and various IOT (internet of things) data. The data retrieval module can support retrieval modes such as POI (point of interest) data retrieval, region retrieval, circled area retrieval and the like. The multi-dimensional data visual superposition analysis module can realize visual superposition analysis of multi-dimensional data, can be used for remote sensing image data viewing, video data viewing, meteorological site data viewing and meteorological grid data viewing, and can perform RGB channel wave band switching, multi-scale data scaling, multi-period data rolling curtain analysis and other processes on the remote sensing image data; aiming at video data, the method can play in a fixed window, check alarm time, handle alarm events and the like; aiming at meteorological site data, site longitude and latitude information, site wind direction information, site temperature and humidity information and the like can be obtained through analysis; for the weather raster data, analysis processing such as air temperature prediction, precipitation prediction, humidity prediction, and the like can be performed based on the weather raster data. And, the presentation of all data in the system is based on the map to be retrieved (three-dimensional/two-dimensional geospatial data). The task management module can uniformly manage tasks corresponding to each search dimension, such as remote sensing AI interpretation tasks, video AI alarm tasks and the like.
Aiming at massive space-time data such as satellites, unmanned aerial vehicles, cameras, IOT equipment, meteorological sites and the like, the sky-ground integrated data retrieval, management and task scheduling system, namely the data fusion retrieval analysis system, is innovatively designed. The multi-scale POI retrieval, space retrieval and attribute information retrieval of multi-source earth observation data such as remote sensing, video and the like are supported, the retrieval result can be analyzed and displayed in a fusion mode on line, and the multi-scale POI retrieval method is applied to combination scenes of regular remote sensing detection of water area shoreline changes and intelligent river and lake dynamic video supervision. The system supports access to authoritative meteorological data such as air temperature, precipitation and humidity and IOT site data, provides dynamic prediction, and can meet scene requirements such as agricultural production assistance.
Referring to fig. 2, fig. 2 shows a flowchart of a data retrieval method according to an embodiment of the present disclosure, which may specifically include the following steps.
Step 202: and responding to the space retrieval instruction, and determining a corresponding target area in the map to be retrieved according to the area information carried by the space retrieval instruction.
The data retrieval method provided by the embodiment of the present disclosure may be applied to the data fusion retrieval analysis system shown in fig. 1, and this step may be performed by the data retrieval module in the system.
As an example, the target area may be a region of interest, a key monitoring area, or any area in the map to be retrieved. The map to be searched can be a two-dimensional or three-dimensional map, is generated according to two-dimensional or three-dimensional space geographic information, supports three-dimensional view and plane view switching, is accessed into a user-defined remote sensing image map and vector map data service, and can be overlapped, analyzed and checked with the dimensional data obtained through searching.
In a specific implementation, a search area determination control can be displayed on a search page, and the search area determination control can be a filling control or a selection control. If the search area determining control is a filling control, the user can fill the area information of the target area in the input box corresponding to the search area determining control, the system can generate a space search instruction according to the area information input by the user, and the search mode can be called as POI point location name address fuzzy search; if the search area determining control is a selection control, the user can select the target area by triggering the selection control, and the system can generate a space search instruction according to the selection of the user, and the search mode can be called zone search. Or the map to be searched can be displayed on the search page, the user can automatically circle a target area in the map to be searched, and the system generates a space search instruction according to the circle operation of the user, and the search mode can be called autonomous circle search. Since the spatial retrieval instruction includes area information, which may be position information of the target area, such as longitude and latitude, coordinates, and the like, a corresponding target area may be determined in the map to be retrieved based on the position information.
In addition, the search page can also display selection controls of other search conditions so as to carry out finer screening on the data based on the other search conditions. By way of example, referring to fig. 3, fig. 3 shows a schematic diagram of a data search page provided according to an embodiment of the present disclosure, where the data search page includes a search area determination control, the search area determination control is a fill-in control, the fill-in control is used for a user to input an area keyword (e.g., please input an area keyword in the page is the fill-in control), and the data search page further includes a shooting date selection control and a resolution selection control. Alternatively, in the data retrieval page, the user may use a circled manner to circle the target area in the map to be retrieved.
The data retrieval method provided by the embodiment of the specification supports various space retrieval modes such as fuzzy retrieval of the point location name and address of the POI, division, autonomous circling and the like, and improves the diversity of data retrieval. In addition, the data attribute information such as acquisition time, influence resolution and the like can be combined to serve as a supplementary search condition for data search, so that on-demand search is realized, and the accuracy of search is improved.
Step 204: and displaying at least two retrieval dimension controls corresponding to the target area, wherein the retrieval dimension controls are used for retrieving dimension data of the corresponding retrieval dimension.
Wherein the dimensional data of different search dimensions characterize the environmental characteristics of the target area from different angles, and the dimensional data of different search dimensions may be data of different structures.
In the present embodiment, this step may include two implementations.
The first implementation mode: after the target area is determined, the user does not need to execute any operation, at least two retrieval dimension controls corresponding to the target area are displayed, and the automation degree is higher.
The second implementation mode: after the target area is determined, the user clicks the displayed search control, and the system responds to the operation of the user to display at least two search dimension controls corresponding to the target area.
And, whichever implementation, the at least two search dimension controls may be independent of, or may be related to, the target region.
In one possible scenario, the at least two search dimension controls presented are identical for any target region, and are not used as filtering for the system, and are simple to operate.
In another possible case, for some reasons, dimensional data of some areas in a certain search dimension on the map to be searched may not be collected or not collected, so that there may be a situation that the dimensional data of some areas in the certain search dimension is missing, based on this, if the search dimension corresponding to the displayed search dimension control does not have the dimensional data, the displayed search dimension control is meaningless, not only occupies page space, but also misleads the user to perform meaningless operation and wastes time. Thus, the at least two search dimension controls to which they correspond may be determined from the target area, i.e. the at least two search dimension controls presented may be different for different target areas.
In a specific implementation, the system may store dimension data of each region in the map to be searched in each search dimension, so, for a target region, the system may determine, according to region information of the target region, dimension data including which search dimensions correspond to the target region, determine the search dimensions as search dimensions corresponding to the target region, select at least two search dimensions from the search dimensions, and display a search dimension control of the at least two search dimensions.

As an example, the remote sensing data is data collected by a remote sensing data collection device such as a satellite or an aviation device, and the remote sensing data may include an image identifier, an area (province/city/county), an image resolution, an image collection time (i.e., a shooting date), an image uploading time (i.e., an uploading date), a device identifier, and the like. The image identifier may be an image name, and the device identifier may be a device name of the remote sensing data acquisition device. For example, referring to fig. 4, fig. 4 illustrates a schematic diagram of a remote sensing data store provided in accordance with one embodiment of the present description.

In a specific implementation, a user can select a target search dimension control from the at least two search dimension controls, and click the target search dimension control to trigger a search instruction of a target search dimension, wherein the target search dimension control is any one or more of the at least two search dimension controls. The user clicks the target retrieval dimension control to trigger a retrieval instruction of a corresponding target retrieval dimension, and at this time, the user is stated to want to view dimension data of a target area in the target retrieval dimension, so that dimension data of the target retrieval dimension can be obtained, and in order to fuse and display dimension data of different retrieval dimensions, environmental features of the target area can be displayed more intuitively, the dimension data of the target retrieval dimension can be displayed on the dimension data displayed at present in a superposition mode.
In a first possible implementation manner of the present disclosure, if any search dimension control is not triggered before the current time, that is, any search instruction is not received before the current time, a search instruction of a target search dimension is received, and dimension data of the target search dimension is not displayed, the currently displayed dimension data may be a map to be searched.
In a second possible implementation manner of the present disclosure, if any search dimension control is not triggered before the current time, that is, any search instruction is not received before the current time, the map to be searched may be displayed by default, and dimension data of the target area in the basic search dimension is displayed at the target area on the map to be searched, so, in the case that the search instruction of the target search dimension is received, and the dimension data of the target search dimension is not displayed, the currently displayed dimension data may include the dimension data of the map to be searched and the target area in the basic search dimension.
In a third possible implementation manner of the present disclosure, if a search dimension control is triggered before the current time, that is, a search instruction of a certain search dimension is received before the current time, dimension data of a certain search dimension is displayed on a map to be searched in an overlapping manner, so that when a search instruction of a target search dimension is received and the dimension data of the target search dimension is not displayed, the dimension data currently displayed may include dimension data of the map to be searched and the target region in the certain search dimension.

As an example, priorities may be set for each search dimension, and the dimension data of the search dimension with a lower priority is displayed on the basis of the dimension data of the search dimension with a higher priority.
