We present the first comparison of Sentinel-2A (S2) MSI (Multi-Spectral Instrument) and Landsat 8 (L8) OLI (Operational Land Imager) data in the retrieval of forest canopy cover (CC), effective canopy cover (ECC), and leaf area index (LAI). The elevation data used for relief displacement of the L1TP data include. Sentinel-2 slightly better than Landsat 8 in the estimation of canopy cover and LAI. Rare Landsat 8 & Sentinel-2 Imagery Comparison Download (Same Date & Extent, 15 minutes apart) Landsat 8 has a 16-day revisit time, with generous overlap between scenes which results in an 8-day revisit time for those areas; Sentinel-2A & 2B has a combined 5 … When using similar bands, the accuracies of Sentinel-2 and Landsat 8 were similar. The transformation functions were developed using ordinary least squares (OLS) regression and were fit quite reliably (r2 values > 0.7 for the reflectance data and > 0.9 for the NDVI data, p-values < 0.0001). Comparison of Sentinel-2 and Landsat 8 in the estimation of boreal forest canopy cover and leaf area index. ETM+ B1 = OLI B2). In the case of insufficient reference data, a systematic and terrain corrected L1GT or a systematic L1GS product will be created instead. How does libxc calculate the potential of GGA? The distribution of the RMSE for each sensor shows significant improvement as sensor and spacecraft technologies evolve, as of February 28, 2019. The accuracy of the L1GT systematic product approaches that of an L1TP product. Landsat 1-5 MSS Collection 1 L1T RMSE: Less than 12 meters in 1.23 percent of the data. Geographic Information Systems Stack Exchange is a question and answer site for cartographers, geographers and GIS professionals. As expected OLI’s narrower panchromatic band is providing better spectral contrast over land surfaces. Sentinel-2 slightly better than Landsat 8 in the estimation of canopy cover and LAI. Given the poor internal geometry of the Multispectral Sensor (MSS) aboard Landsat 1-5, the use of ground control even for data with large RMSE was considered preferable, to creating a large proportion of data as L1GS with the internal geometry uncorrected. Is there something wrong with my fictional lighthouse? From Landsat 8 handbook p. 61. The 705 nm red edge band was commonly selected into the Sentinel-2 models. Landsat TM and MSS images may be offset from its correct spatial location by thousands of meters, preventing the use of terrain correction for systematic products. Does prolonged (lifetime) exposure to strong and chaotic geomagnetic storms have any side-effects? Does the effect of the Jungle Drums upgrade stack with multiple Monkey Villages? The instruments on Landsat 8 have linear detector arrays, also called "pushbroom" detectors, which collect data across the entire image swath at once. Landsat scenes are processed to a Level-1 precision and terrain corrected product (L1TP) if possible. If precision correction fails from the path/row group that has produced at least one L1TP, the scene becomes an L1GT FB (fallback).
