ARCHIVE CONTENTS

The data contained in this archive are the final version of Urban Landsat: Cities from Space.

This archive 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 30x30 meters 
in area and most images are 30x30 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 1000x1000x6 4 byte floating point numbers as indicated in the 
header. 

Further information is available from the Landsat Data Users Handbook. 

Analyses of the images are described in: 
Small, C., Global Analysis of Urban Reflectance, International Journal of Remote Sensing, 
v.26, n.4, p.661-681, 2005.
