The most widely known remote-sensing data are satellite images (typically LANDSAT or other visible imagery), which are used in the geosciences for a multitude of applications, including landuse, urbanization, sea-ice expansion, to name only a few. Commonly, these remote-sensing data are analyzed with the help of commercial software systems (eg. ENVI, ERDAS-IMAGINE). Analysis methods employ the ...

Figure 4. Example of a well pad & road network w/a high-pass filter over ETM imagery. The Southern Wind River Landscape (SWRL) is a three million acre area of Intermountain Semidesert in west central Wyoming. Within the three million acres lie both public and private land holdings. The Nature Conservancy (TNC) has significant conservation interests in this Landscape as well and has created a ne...

In this paper, space image of the Quick Bird satellite a pixel size 0.6m*0.6m for year 2007 were merge layers through layer stack process from seven to three and combined in color composites using ERDAS Imagine Ver. 9.2. Also monitoring ground control points with coordinates E, N, monitored by Differential Ground Position System (DGPS) device these are processed OPUS site internet. The results ...

Assessing the impact of land use and climate change on streamflow is important for watershed management. This study aims to examine possible impacts Jewaha catchment. The Soil Water Assessment Tool (SWAT) model used simulate by integrating complex interactions between use/cover. past land-use changes were determined classifying Landsat images from 1990, 2000, 2018 with Earth Resource Developmen...

This paper aims at effectively detecting the building changes in bi-temporal very high resolution satellite images. Many applications require detecting structural changes in a scene over a period of time. Change detection of man-made objects using remote sensing images has many applications such as city planning, informal building detection and disaster management. For this paper, two bi-tempor...

(221Wörter) Satellite remote-sensing data for urban land-cover and land-use mapping has been investigated over a long time using increasingly more powerful data and more sophisticated techniques. Well-established methods for surveying urban habitats such as aerial photography have to be replaced now for updating previous results. At present additional benefits result from high resolution airbor...

Identified by the EPA as the leading threat to surface water quality in the United States, nonpoint source (NPS) pollution is channeled into rivers and streams via impervious surfaces. Impervious surfaces are anthropogenic features, such as roads, buildings, and parking lots, through which water cannot infiltrate into the soil. Research from the past 15 years shows a consistent, inverse relatio...

The Upper Benue Trough is part of the Benue Trough of Nigeria and is comprised of three basins: the east–west trending Yola Basin (Yola Arm), the north– south trending Gongola Basin (Gongola Arm) and the northeast– southwest trending Lau Basin (Main Arm). This research is an ongoing research at understanding the structural framework of the Upper Benue Trough using several techniques including t...
