description The invention discloses an elevation data processing method, which comprises the following steps: carrying out hierarchical slicing on elevation data, and determining a first elevation interval; calculating an elevation difference value of each adjacent elevation point, when the elevation difference value is determined to be greater than a first threshold value, calculating and generating a first quantized elevation difference value taking a first elevation interval as a counting unit, and storing the first quantized elevation difference value in an elevation array of a preset first storage file; when it is determined that the elevation difference value is smaller than or equal to a first threshold value, whether the elevation difference value is larger than a second threshold value or not is judged; if yes, a second quantized elevation difference value with the first elevation interval as a counting unit is calculated and generated, and the second quantized elevation difference value is stored in an elevatio
