The Urban Landsat: Cities from Space dataset contains images for 66 urban areas and the raw, unerlying data for 28 of these places. 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. This dataset is distributed by the Socioeconomic Data and Applications Center (SEDAC) at Center for International Earth Science Information Network (CIESIN), Columbia University.
The data in ENVI Band Sequential (BSQ) format and images in Portable Document Format (PDF) and Portable Network Graphics (PNG) formats are available from the NASA Socioeconomic Data and Applications Center (SEDAC).
