While there is no longer a need to transition from one service to another, the ObjectID for each image will change. A conceptual introduction and practical primer to the application of imagery and remote sensing data in GIS (geographic information systems). Landsat 8 Collection 1 Tier 1 and Real-Time data DN values, representing scaled, calibrated at-sensor radiance. In the future, if these need to be adjusted, then all archived images . If you want historical scenes, use: Landsat -> Landsat Collection 2 Level-1 -> Landsat 4 - 5 TM C1 Level-1. Landsat L1 product metadata is contained in .MTL archive, L1 level are Landsat products in DN or TOA reflectance.Higher Level Landsat Image in BOA reflectance has another kind of metadata structure. To do this requires setting various parameters which depend on the collection you are querying.
