| Abstract: | This paper introduces the principle of GDAL and NetCDF,especially the advantages on image data processing and grid data attempering.A new method of building image pyramid based on GDAL and NetCDF is put forward,which optimized the key technology of index.And the operating efficiency of resampling is tested to be increased.Thereby,the article provided the theoretic and practical foundations in this field. |
