Method for generating contour map in real time based on monitoring data

The invention relates to a method for generating a contour map in real time based on monitoring data. The method comprises the following steps: acquiring monitoring data on each monitoring point site at regular time; determining a map of a monitoring area according to the distribution position of each monitoring point position, taking the map of the monitoring area as a base map of a contour map, and recording the longitude and dimension ranges of the base map; determining parameters of the contour map and data acquisition time according to the monitoring data, and generating a data file, with the format of the data file being 'longitude, latitude and numerical value'; according to the data file, calling a Kriging interpolation algorithm in a SurferAPI, and determining a grid file of the contour map; determining a level file used by the SurferAPI according to the data file; and importing the grid file, the level file and the base map by utilizing the SurferAPI, and generating the contour map consistent with t
