| | 3 | This command creates reduced resolution images, also known as a pyramid image structure from the input image. |
| | 4 | Reduced resolution layers are created by iteratively downsampling the full resolution image. The results are stored in a .ovr (overview) file. This structure improves the efficiency of arbitrary access to different spatial resolutions and areas of interest. The OSSIM library will automatically select the appropriate layer and area of interest for needed operations. |
