Description

Technical Field

[0001] The present invention relates to the technical field of longitude and latitude of monitoring points, and particularly relates to a method, device and medium for detecting and correcting abnormal spatial positions of monitoring points. Background Art

[0002] When conducting environmental monitoring, it is usually necessary to arrange monitoring points in the monitoring area [1] , and during the process of collecting environmental samples and monitoring data, it is necessary to accurately record the spatial position information of the monitoring points, that is, longitude and latitude, to clearly identify the location or area represented by the obtained monitoring data [2] . However, in the process of manual recording or data reporting, there will be phenomena such as misplacing the decimal point of longitude and latitude or filling in the longitude and latitude values in the wrong position (reversed), resulting in the situation that when the monitoring points and their corresponding monitoring data are marked on the map according to the recorded longitude and latitude, the marked location does not match the location set during the arrangement of the monitoring points, and the display of regional environmental information is incorrect.

[0003] The traditional correction method is to first mark the monitoring points on the map according to the recorded longitude and latitude, then manually search for the monitoring points that fall outside the boundary of the map monitoring area, or the points whose longitude and latitude are obviously inconsistent with the location they should belong to, and then find the original sampler and recorder for each point to verify the longitude and latitude, or compare and verify with the location and longitude and latitude shown in the sampling environment photos taken during sampling. The verification and correction efficiency is low, time-consuming and laborious. When the monitoring area is large and there are many monitoring points, manual verification cannot meet the requirements of the actual data result summary time limit, and manual verification is also prone to errors. Therefore, in view of the above deficiencies, this solution proposes a method, device and medium for detecting and correcting abnormal spatial positions of monitoring points.
