| Abstract: | The specific of isoline process of homogeneous gridding data are briefly analyzed This paper detaliedly introduces three methods used for processing heterogeneous gridding data,that is,weighing least square method by distance (namely N-P method),weighing pointing method by azimuth weigh method and fitting method by weighing least square method (namely M-S method) Microsoft Visual C source programs for N-P method and M-S method are provided in this paper |
| Keywords: | Seismic data processing Gridding data Isoline process N-P method M-S method |
