Method for displaying real-time pdome value of satellite by using digital earth

The invention discloses a satellite real-time pdome value display method by using a digital earth, which comprises the following steps of: S1, selecting a plurality of red, green and blue (RGB) colors, and completing coloring rendering correspondence between the digital earth and selected RGB color values and color segment values according to blocks; s2, acquiring real-time pdome values of satellites according to blocks; s3, acquiring a corresponding real-time RGB color value according to the real-time pdome value of each block; s4, finishing the coloring rendering of the digital earth according to the real-time RGB color value of each block; according to the method, the pdome values are visually displayed in different colors on the digital earth, the distribution condition of space satellites is displayed on the digital earth, meanwhile, the real-time pdome value condition of each block of the satellites at the current moment can be visually displayed through different colors, the satellite distribution cond
