M. A. Kalkhan, R.M. Reich, T.J. Stohlgren
1998, International Journal of Remote Sensing (19) 2049-2060
Double sampling was used to provide a cost efficient estimate of the accuracy of a Landsat Thematic Mapper (TM) classification map of a scene located in the Rocky Mountain National Park, Colorado. In the first phase, 200 sample points were randomly selected to assess the accuracy between Landsat TM data...

Comparison of Landsat Thematic Mapper and high resolution photography to Identify change in complex coastal wetlands
Elijah Ramsey III, S.C. Laine
1997, Journal of Coastal Research (13) 281-292
Landsat Thematic Mapper (TM) images were used to generate pre- and post- hurricane classifications of a complex wetland environment in southern Louisiana. Accuracies were estimated as 77% and 81.5% for the pre- and post- classifications that included water, emergent vegetation, floating vegetation, and mud flats. From the two classifications, areas...

Assessment of acreage and vegetation change in Florida's Big Bend tidal wetlands using satellite imagery
Ellen A. Raabe, Richard P. Stumpf
1997, Book, Proceedings of the fourth international conference on remote sensing for marine and coastal environments: technology and applications
Fluctuations in sea level and impending development on the west coast of Florida have aroused concern for the relatively pristine tidal marshes of the Big Bend. Landsat Thematic Mapper (TM) images for 1986 and 1995 are processed and evaluated for signs of change. The images cover 250 km of Florida's...

1997, Canadian Journal of Remote Sensing (23) 318-332
Landsat-7 is currently being built and tested for launch in 1998. The Enhanced Thematic Mapper Plus (ETM+) sensor for Landsat-7, a derivative of the highly successful Thematic Mapper (TM) sensors on Landsats 4 and 5, and the Landsat-7 ground system are being built to provide enhanced radiometric calibration performance. In...
Landsat TM memory effect characterization and correction
D. Helder, W. Boncyk, R. Morfitt
1997, Canadian Journal of Remote Sensing (23) 299-308
Before radiometric calibration of Landsat Thematic Mapper (TM) data can be done accurately, it is necessary to minimize the effects of artifacts present in the data that originate in the instrument's signal processing path. These artifacts have been observed in downlinked image data since shortly after launch of Landsat 4...

L. T. Steyaert, F.G. Hall, Thomas R. Loveland
1997, Journal of Geophysical Research D: Atmospheres (102) 29581-29598
A multitemporal 1 km advanced very high resolution radiometer (AVHRR) land cover analysis approach was used as the basis for regional land cover mapping, fire disturbance-regeneration, and multiresolution land cover scaling studies in the boreal forest ecosystem of central Canada. The land cover classification was developed by using regional field...
Martian drainage densities
M. H. Carr, F. C. Chuang
1997, Journal of Geophysical Research E: Planets (102) 9145-9152
Drainage densities on Mars range from zero over large areas of volcanic plains to 0.3–0.5 km−1 locally on some volcanoes. These values refer to geologic units, not to drainage basins, as is normal for terrestrial drainage densities. The highest values are close to the lowest terrestrial values derived by similar techniques....
Aerial Photographs and Satellite Images
Water Resources Division, U.S. Geological Survey
1997, Report
Photographs and other images of the Earth taken from the air and from space show a great deal about the planet's landforms, vegetation, and resources. Aerial and satellite images, known as remotely sensed images, permit accurate mapping of land cover and make landscape features understandable on regional, continental, and even...

Steven T. Knick, J.T. Rotenberry, T.J. Zarriello
1997, Photogrammetric Engineering and Remote Sensing (63) 79-86
In this article the authors used a nonparametric discriminant function in a supervised classification of Landsat Thematic Mapper satellite imagery of a ~240,000-ha semi-arid region in the Snake River Plains, southwestern Idaho. First, agriculture pixels were classified by distance from the soil baseline and water pixels by the thermal band...
