Urban Landsat

Urban Landsat: Cities from Space, v1 (1999 – 2003)

These archives contains jpeg images of 66 urban areas and binary, raw input data for a subset (28 total) of these countries. Each image shows a Landsat false color composite in UTM projection.  The R/G/B layers correspond to TM/ETM+ bands 7/4/2.  Each pixel is 30×30 meters in area and most images are 30×30 km in area.  A 2% linear stretch has been applied to the images.

The Landsat data files contain six reflected bands of calibrated exoatmospheric reflectance stored in ENVI band sequential (BSQ) format. Geographic coordinates are included in the header file.  The data file contains 1000×1000×6 4 byte floating point numbers as indicated in the header. For additional information, please refer to the README file.
