Abstract: The present disclosure relates to a method of editing terrain data created by a procedure method, and particularly to a method of editing terrain data based on multiresolution for intuitively editing high-quality terrain data. To this end, the method of editing terrain data created by a procedure method includes: inputting terrain data in a form of a height map; processing a multiresolution analysis by dividing the input height map for each band; processing a terrain edition based on the multiresolution by adjusting a height value within a predetermined distance from a position selected from the multiresolution analyzed height map; and storing the multiresolution-based terrain edition processed height map in a form of a progressive mesh.
