Spectral characterization of desert surfaces in Kuwait by satellite data
… their spectral signatures as detected by Landsat Thematic Mapper (TM) data. A sophisticated image analysis was applied to the Landsat TM scene. An unsupervised classification technique produced a thematic map of the area. Data was collected on the ground at eighty sites in southeastern …

The Use of Landsat Thematic Mapper in the Study of Landuse/Cover and Water Quality Relationships
… Jordan. Landuse changes were detected by using Landsat Thematic Mapper (TM) images obtained for King Talal reservoir in 1990 and 2006 and for Karameh reservoir in 1998 and 2006. Geometric correction and supervised classification were utilized in ERDAS software. Turbidity levels within the two …

Identifying structural differences in mixed mesophytic and northern hardwood forests on the Monongahela National Forest using remote sensing data
… techniques applied to SPOT Panchromatic and Landsat Thematic Mapper (TM) satellite data resulted in limited success. Wetness, a TM Tasseled Cap transformation, was the spectral variable most correlated with stand age. Although TM texture was found to be related to differences in stand age, TM …

Land Cover of Virginia From Landsat Thematic Mapper Imagery
… Virginia, produced through interpretation of 14 Landsat Thematic Mapper (TM) scenes, circa 1991-1993. The land cover map, which has a 30m pixel size, was produced entirely with personal computers. Hypercluster aggregation, an unsupervised classification method, was used when hazy and mountainous …

Weighting Landsat Digital Data According to Land Cover Emissivity for Surface Temperature Mapping
… data acquisition and a synoptic view make the Landsat Thematic Mapper (TM) an excellent resource for entities needing land cover and surface temperature information. Landsat 5 TM digital data (1985) are used to classify land cover in the vicinity of New Orleans, the study area encompassing …

Volcanology from space: applications of infrared remote sensing
… short wavelength infrared (SWIR) bands of the Landsat Thematic Mapper (TM) are used to constrain sizes and temperatures of subpixel resolution hot spots. Analysis of a 1989 TM scene of Lonquimay volcano suggests a cooling from 250 to 170°C of the crust of an active lava flow down 1.5 km of its …

Estimating Sources of Valley Fever Pathogen Propagation in Southern Arizona: A Remote Sensing Approach
… rasters. Surface temperature, derived from Landsat TM thermal images, is the most widely selected predictive variable in both automated methods. Construction-related soil disturbance (e.g. road construction, trenching, land stripping, and earthmoving) is a significant source of fugitive …

Lineament and pegmatite mapping using landsat TM imagery and aerial photograph data: Kaseba-Katota Area, Serenje district, Central Zambia
… of geology, lineaments, faults (interpreted from Landsat Thematic Mapper (TM) image and aerial photographs), joints and foliation traces (mapped in the field). Remote sensing techniques. Geographic Information Systems (GIS) as well as statistical analyses applied to this digital database and the …

Impact of military maneuvers on Mojave Desert surfaces: A multiscale analysis
… Images created from SPOT panchromatic and Landsat Thematic Mapper (TM) multispectral data acquired during the spring of 1987 and 1993 were analyzed to assess both the extent of disrupted surfaces and the surface geomorphology discernable from satellite data. Classified and merged images …

Land development in Massachusetts: Its effect on the environment within Essex and Middlesex counties from 1990 to 2007
… change detection method was applied to Landsat Thematic Mapper (TM) satellite data and GIS was used to detect, quantity, and document the extent of development and its effect on the environment and to assess and quantify the demographic changes that occurred within the counties from 1990 …

Detecting long-term trends in water quality parameters using remote sensing techniques
… I evaluated the use of moderate resolution Landsat-5 TM imagery for estimating three indicators of water quality: Secchi depth (SDD), chlorophyll-a concentration (Chl-a), and dissolved organic carbon (DOC). Reflectance and in situ data were collected within seven days of satellite overpass …
