Resolutions of Remote Sensing - University of Rhode Island
www.edc.uri.eduFor example, we often speak of Landsat as having “30-meter" resolution, which means that two objects, thirty meters long or wide, sitting side by side, can be separated (resolved) on a Landsat image. Other sensors have lower or higher spatial resolutions. Comparison of Landsat Sensors Thematic Mapper (TM) Landsat 4 and 5 Enhanced Thematic
