Embodiment 1
[0055] Please refer to figure 1 , a raster data visualization method based on a three-dimensional earth model provided in an embodiment of the present invention, including:
[0056] Step 101: Receive a raster data file uploaded by a user, and perform data processing on the raster data file to obtain multiple grid point data.
[0057] In this embodiment, the papaparse.js library is used to convert the raster data file in CSV format uploaded by the user into a two-dimensional Array object that is easy to handle in JavaScript, wherein the two-dimensional Array object includes multiple grid point data, which is convenient for subsequent data use. It is also possible to use other methods or software to convert the raster data file into a two-dimensional Array object containing multiple grid point data.
[0058] Step 102: Create a Canvas element according to multiple grid point data; wherein, the resolution of the Canvas element is determined according to the corresponding multipl...
