The TIR band, while originally collected with a resolution of 120m / pixel Surface Reflectance. (Obtained from raw Landsat metadata), Internal ESPA image version used to compute SR, Combined RMSE (Root Mean Square Error) of the geometric global,sr,reflectance,ledaps,cloud,fmask,cfmask,le07, directions. as well as a per-pixel saturation mask. If you have any questions, suggestions or spotted a mistake, please use the comment function at the bottom of this page. These images contain 4 visible and near-infrared (VNIR) bands and 2 short-wave infrared (SWIR) bands processed to orthorectified surface reflectance, and one thermal infrared (TIR) band processed to orthorectified brightness temperature. The VNIR and SWIR bands have a resolution of 30m / pixel. the LEDAPS product guide. Right now the collection "COPERNICUS/S2_SR" only has 30K out of 1M+ expected assets. over high latitudes (> 65°).

Band 1 (ultra blue) surface reflectance. been resampled using cubic convolution to 30m. temperature. and include a cloud, shadow, water and snow mask produced using Since the 27th of March 2019 has the Earth Engine data catalogue one more dataset. (Obtained from raw Landsat metadata), LEDAPS version used to process surface reflectance. Efficacy of SR correction will be likely reduced in areas This blog post teaches you in one minute, how to get the current Sentinel-2 ingestion status for your country. Cloud quality attributes. Band 1 (blue) surface reflectance. (Obtained from raw Landsat metadata), Landsat Product Identifier (Collection 1), Date of production for raw Level 1 data as ms since epoch, Version of the software used to produce the 'pixel_qa' band, Time of the observations as in ISO 8601 string. B3: 0.0001: 0.63-0.69 μm: Band 3 (red) surface reflectance. where atmospheric correction is affected by adverse conditions: Coastal regions where land area is small relative to adjacent water. Specifically, there are methods to compute at-sensor radiance, top-of-atmosphere (TOA) reflectance, surface reflectance … Pixel quality attributes generated from the CFMASK algorithm. corrected surface reflectance from the Landsat 7 ETM+ sensor. Band 4 (near infrared) surface reflectance, Band 5 (shortwave infrared 1) surface reflectance. Band 6 brightness temperature. If you would like to get the information on a country level you could to the following: We could also count the amount of images for every MGRS Tile and list them. Feel free to connect or follow me on twitter - gartn001. The VNIR and SWIR bands ... LANDSAT/LE07/C01/T1_SR, than sr_cloud_qa for cloud masking. Earth Engine contains a variety of Landsat specific processing methods. This product is generated by Google using a Docker image supplied by USGS. precision correction in the across-track direction. measured on the GCPs (Ground Control Points) used in geometric SR can only be produced for Landsat assets processed to the (60m / pixel for Landsat 7) has been resampled using cubic convolution to 30m. CFMASK, Note: pixel_qa is likely to present more accurate results measured on the GCPs (Ground Control Points) used in geometric Earth Engine is free to use for research, education, and nonprofit use.
