Use of Argon, Corona, and Landsat imagery to assess 30 years of land resource changes in west-central Senegal
G. Gray Tappan, Amadou Hadj, Eric C. Wood, Ronald W. Lietzow
2000, Photogrammetric Engineering and Remote Sensing (66) 727-735
Over the past 35 years, an agricultural area of west-central Senegal has experienced rapid population growth, fast expansion of agricultural lands, a decline in rainfall, and degradation of vegetative and soil resources. Although such changes have not escaped the attention of Senegal's people, its government, and the scientific community the...

2000, Conference Paper, EEE 2000 International Geoscience and Remote Sensing Symposium. Taking the Pulse of the Planet: The Role of Remote Sensing in Managing the Environment. Proceedings
Policy-makers and scientists often require comprehensive data on the types and rates of land use and land cover change at a variety of scales. However, there is generally a lack of local, regional, and national land use and land cover data of sufficient reliability and temporal and geographic detail for...

New structural and stratigraphic insights for northwestern Pakistan from field and Landsat Thematic Mapper data
J. Robinson, R. Beck, E. Gnos, R.K. Vincent
2000, Geological Society of America Bulletin (112) 364-374
The remote Waziristan region of northwestern Pakistan includes outcrops of the India-Asia suture zone. The excellent exposure of the Waziristan ophiolite and associated sedimentary lithosomes and their inaccessibility made the use of Landsat Thematic Mapper (TM) data desirable in this study. Landsat TM data were used to create a spectral...
Scaling up from field to region for wind erosion prediction using a field-scale wind erosion model and GIS
T.M. Zobeck, N. C. Parker, S. Haskell, K. Guoding
2000, Agriculture, Ecosystems and Environment (82) 247-259
Factors that affect wind erosion such as surface vegetative and other cover, soil properties and surface roughness usually change spatially and temporally at the field-scale to produce important field-scale variations in wind erosion. Accurate estimation of wind erosion when scaling up from fields to regions, while maintaining meaningful field-scale process...

Change analysis in the United Arab Emirates: An investigation of techniques
Terry L. Sohl
1999, Photogrammetric Engineering and Remote Sensing (65) 475-484
Much of the landscape of the United Arab Emirates has been transformed over the past 15 years by massive afforestation, beautification, and agricultural programs. The "greening" of the United Arab Emirates has had environmental consequences, however, including degraded groundwater quality and possible damage to natural regional ecosystems. Personnel from the...
Multispectral multisensor image fusion using wavelet transforms
George P. Lemeshewsky
1999, Conference Paper, Proceedings of SPIE - The International Society for Optical Engineering
Fusion techniques can be applied to multispectral and higher spatial resolution panchromatic images to create a composite image that is easier to interpret than the individual images. Wavelet transform-based multisensor, multiresolution fusion (a type of band sharpening) was applied to Landsat thematic mapper (TM) multispectral and coregistered higher resolution SPOT...
Analysis of land use change in urban environments
Water Resources Division, U.S. Geological Survey
1999, Fact Sheet 188-99
Metropolitan areas in the United States are growing at unprecedented rates, creating extensive urban landscapes. Many of the farmlands, wetlands, forests, and deserts that formed the America of 1900 have been transformed during the past 100 years into human settlements. Almost everyone has seen these changes to their local environment...
Glaciers of South America
Richard S. Williams Jr., Jane G. Ferrigno
1998, Professional Paper 1386-I
Landsat images, together with maps and aerial photographs, have been used to produce glacier inventories, define glacier locations, and study glacier dynamics in the countries of South America, along with the Andes Mountains. In Venezuela, Colombia, Ecuador, and Bolivia, the small glaciers have been undergoing extensive glacier recession since the...

In the first phase, 200 sample points were randomly selected to assess the accuracy between Landsat TM data...
Regional characterization of land cover using multiple sources of data
James E. Vogelmann, Terry L. Sohl, Stephen M. Howard
1998, Photogrammetric Engineering and Remote Sensing (64) 45-57
Many organizations require accurate intermediate-scale land-cover information for many applications, including modeling nutrient and pesticide runoff, understanding spatial patterns of biodiversity, land-use planning, and policy development. While many techniques have been successfully used to classify land cover in relatively small regions, there are substantial obstacles in applying these methods to...
