Image Interpretation

How to View Synthetic Aperture Radar (SAR) Imagery

Most SAR products are delivered in either CEOS or GeoTIFF file formats. These file formats will not display in both Windows and Mac default image viewers. However, you can view GeoTIFFs in a GIS program. In addition, both GeoTIFF and CEOS images can be viewed using free downloadable software from ASF called ASFView. The ASFView tool for SAR image interpretation is included when you download ASF’s MapReady software.
