Problems solved by technology

If non-professional users cannot accurately select the corresponding conditions, especially satellite and sensor types, due to lack of knowledge about satellites and other related knowledge, for non-professional users, the process of inputting and selecting conditions one by one is very complicated;
[0004] When non-professional or professional users retrieve the remote sensing data due to multiple IP addresses, the database will always be in the loading process, and then the required satellite data cannot be extracted quickly; in view of the above problems, the present invention has carried out corresponding improvements

Embodiment 1

[0064] Embodiment 1: Obtain the time period, wherein the time period is: one and a half hours=3 30 minutes, the number of times J={35,60,85} that the satellite data corresponding to the specified target path is queried in the time period; set Y =fx+b; Substituting the value of the above formula to get Y=50x+10, and then it can be predicted that in the second hour, the number of satellite data queries Y=110, then verify H2=β*c=110*0.72=79.2 ; If it is verified that H1=95>H2, the satellite data in the temporary database cannot be replaced according to the comparison of weight values.

Embodiment 2

[0065] Embodiment 2: Obtain the time period, wherein the time period is: one and a half hours=3 30 minutes, the number of times J={35,60,85} that the satellite data corresponding to the specified target path is queried in the time period; set Y =fx+b; Substituting the value of the above formula to get Y=50x+10, and then it can be predicted that in the second hour, the number of satellite data queries Y=110, then verify H2=β*c=110*0.72=79.2 ; If it is verified that H1=60

[0066] The working principle of the present invention: the present invention obtains the coordinate value of the current map base map, calculates the view range area according to the coordinate value, and then obtains the remote sensing satellite image coverage area of ​​the target area; maps through the established database, and then obtains the target data The number of satellites and sensor...

Abstract

The invention discloses an intelligent retrieval method for satellite remote sensing data, and relates to the technical field of remote sensing data processing. The intelligent retrieval method comprises the following steps: Z01, acquiring base map page data of a map; z02, obtaining a satellite image coverage area according to the page data, and obtaining first to-be-processed data of a satellite; z03, taking the first to-be-processed data as a condition for querying the SQL to obtain a query result; z04, generating target path information, and adjusting the storage position of the satellite data information in the database according to the priority; conditions such as time, areas, satellites and sensors required by remote sensing satellite data can be automatically obtained and inquired by analyzing and mapping a page according to the current view range of a user, the conditions are converted into inquiry statements to be inquired to obtain an inquiry result, the inquiry threshold can be lowered, the data inquiry process is simplified, and the inquiry efficiency is improved. The user experience is improved; by establishing the temporary database, the query speed can be increased, and the query result can be displayed.

Description

technical field [0001] The invention relates to the technical field of remote sensing data processing, in particular to an intelligent retrieval method for satellite remote sensing data. Background technique [0002] Remote sensing satellites refer to artificial satellites used as remote sensing platforms in outer space. Remote sensing satellites can cover the entire earth or any area within a specified time, and can perform remote sensing of designated areas; through remote sensing satellites, users can query and obtain satellite data in any area ; [0003] In the existing satellite data open platform, satellite data retrieval usually requires the user to enter the specific area, specific time, specific satellite type, sensor number and other necessary conditions to query the data, all of which are indispensable. If non-professional users cannot accurately select the corresponding conditions, especially satellite and sensor types, due to lack of knowledge about satellites ...
