A simple and effective method for filling gaps in Landsat ETM+ SLC-off images
Jin Chen, Xiaolin Zhu, James E. Vogelmann, Feng Gao, Suming Jin
2011, Remote Sensing of Environment (115) 1053-1064
The scan-line corrector (SLC) of the Landsat 7 Enhanced Thematic Mapper Plus (ETM+) sensor failed in 2003, resulting in about 22% of the pixels per scene not being scanned. The SLC failure has seriously limited the scientific applications of ETM+ data. While there have been a number of methods developed...

Shengli Huang, Devendra Dahal, Claudia Young, Gyanesh Chander, Shuguang Liu
2011, Remote Sensing of Environment (115) 3377-3389
Spatiotemporal variations of wetland water in the Prairie Pothole Region are controlled by many factors; two of them are temperature and precipitation that form the basis of the Palmer Drought Severity Index (PDSI). Taking the 196 km2 Cottonwood Lake area in North Dakota as our pilot study site, we integrated PDSI, Landsat...

Ainong Li, Chengquan Huang, Guoqing Sun, Hua Shi, Chris Toney, Zhiliang Zhu, Matthew G. Rollins, Samuel N. Goward, Jeffery G. Masek
2011, Remote Sensing of Environment (115) 1837-1849
Many forestry and earth science applications require spatially detailed forest height data sets. Among the various remote sensing technologies, lidar offers the most potential for obtaining reliable height measurement. However, existing and planned spaceborne lidar systems do not have the capability to produce spatially contiguous, fine resolution forest height maps...

Xuexia Chen, James E. Vogelmann, Matt Rollins, Donald Ohlen, Carl H. Key, Limin Yang, Chengquan Huang, Hua Shi
2011, International Journal of Remote Sensing (32) 7905-7927
It is challenging to detect burn severity and vegetation recovery because of the relatively long time period required to capture the ecosystem characteristics. Multitemporal remote sensing data can providemultitemporal observations before, during and after a wildfire, and can improve the change detection accuracy. The goal of this study is to...
A self-trained classification technique for producing 30 m percent-water maps from Landsat data
Jennifer R. Rover, Bruce K. Wylie, Lei Ji
2010, International Journal of Remote Sensing (31) 2197-2203
Small bodies of water can be mapped with moderate-resolution satellite data using methods where water is mapped as subpixel fractions using field measurements or high-resolution images as training datasets. A new method, developed from a regression-tree technique, uses a 30 m Landsat image for training the regression tree that, in...

2010, General Information Product 111
For most of us, deserts, mountains, river valleys, coastlines even dry lakebeds are relatively familiar features of the Earth's terrestrial environment. For earth scientists, they are the focus of considerable scientific research. Viewed from a unique and unconventional perspective, Earth's geographic attributes can also be a surprising source of awe-inspiring...

Use of EO-1 Hyperion data to calculate spectral band adjustment factors (SBAF) between the L7 ETM+ and Terra MODIS sensors
Gyanesh Chander, N. Mishra, Dennis L. Helder, David Aaron, T. Choi, A. Angal, X. Xiong
2010, Conference Paper, IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2010 : 25 - 30 July 2010, Honolulu, Hawaii, USA
Different applications and technology developments in Earth observations necessarily require different spectral coverage. Thus, even for the spectral bands designed to look at the same region of the electromagnetic spectrum, the relative spectral responses (RSR) of different sensors may be different. In this study, spectral band adjustment factors (SBAF) are...
