The Landsat 5 mission is in jeopardy. Therefore, the United States Geological Survey (USGS) is exploring ways to alleviate a data gap if both Landsat 5 and 7 missions fail prior to the planned launch of Landsat 8 (known as the Landsat Data Continuity Mission) in 2013 [Randy, 2012]. Using the Chinese HJ1-CCD remote sensing data, analyses were performed on the spectral signature of these two different...
Considering there is great similarity between the wave-band design and spatial resolution of the China HJ1A/1B satellite CCD Camera and Landsat TM data, this paper conducts comparison and analysis to the data from the aspects of track parameter, spectral response characteristics and imaging quality. The orbital parameters have little difference. But HJ satellite has two satellites constellations in...
