I downloaded a S1A GRDH L1 IW data. In sentinel website, it is recorded as high resolution. I check the table here: https://sentinel.esa.int/web/sentinel/user-guides/sentinel-1-sar/resolutions/level-1-ground-range-detected. It said IW high resolution data has pixel spacing 40 * 40. However, i check my data in arcgis, and it shows the pixel spacing is 10 * 10, which is the same with full resolution data.
Does anybody know the reason? Thank you.
