This exercise is based around Chapter 6, which uses the Sentinel Application Platform (SNAP) to display Landsat Level 1 data as a colour composite. It’s a summary of what’s in the book, as the exercises in the book describe each step in greater detail.
We describe in detail how to find, select and download Landsat data from the United States Geological Survey (USGS) website http://landsat.usgs.gov/ using GloVis (http://glovis.usgs.gov/) in Chapter’s 4 and 6. For this exercise, you’ll need to download an image captured on the 27 October 1990 by Landsat 5, covering an area around Warsaw in Poland; the WRS-2 path and row is 188 024.
Download the GeoTIFF data, which will be a compressed tar.gz file. This file will need to be fully unzipped in order to complete this exercise; this process is described in detail in Chapter 6. Once you have unzipped the data:
