 The Landsat-7 Enhanced Thematic Mapper Plus, ETM Plus, and Landsat-8 Operational Land Imager, OLI, and Thermal Infrared Sensor, Terras, are currently in operation for routine Earth observation. Both satellites have made significant improvements compared to previous versions of the Landsat series, including the replacement of WISC Broom Scanners with two separate PushBroom OLI and TRS Scanners, an extension of the number of spectral bands and narrower bandwidths. As such, cross comparisons of these two satellites are essential for accurate analysis of long-term changes in land cover. In this study, 3,311 independent sample points of four major land cover types, primary forest, unplanted cropland, swidden cultivation, and water bodies, were used to compare the spectral bands of ETM Plus and OLI. Eight sample plots with different land cover types were manually selected for comparison with the Normalized Difference Vegetation Index, NDVI, the Modified Normalized Difference Water Index, MNDWI, the Land Surface Water Index, LSWI.
