The globalpositioningsystem and its integration into college geography curricula
Introduces globalpositioningsystem (GPS) technology to nonspecialist geographers and recommends a framework for implementing GPS instructional modules in geography courses. - (DWG)
This system provides for the collection of timely and cost-effective spatial information. Data are collected for an area of rapid rural-to-urban land-use change by using low-cost receivers in static and kinematic modes. They were processed for input
to GIS and assessed for their positional accuracy. The 4 km2 area is located at the northeastern fringe of metropolitan Toronto.
The aim of this study is to use globalpositioningsystem (GPS) to measure the morphology of gullies in a small catchment near Suide, Shaanxi Province, China. There are 3 main gully types in the study area : bank gullies, floor gullies, and hill

This paper describes the methodology employed to resolve vertical changes associated with frost heave and thaw settlement in northern Alaska, at Prudhoe Bay, using differential globalpositioningsystems (DGPS) technology. Traditional profile
differences with regard to the large urban economic centres in West- and East-Germany. The different positions of particular urban economic centres in Germany and Europe as encoring points of global firms' organizational networks are being indicated
with regard to global service providers and global media firms, emphasizing the global interconnections as an important development factor particularly in the metropoles of the urban system. - (IFL)

The flow of information in a global economy: the role of the American urban system in 1990
This paper examines the contemporary production and exchange of higher-order information that occurs among and between American cities and reveals how ongoing globalization has affected the position of these cities in the system of information
exchange. A conceptual framework is introduced, combining processes of uncertainty, deregulation, globalization, and vertical disintegration. A three-tiered hierarchical system is revealed, with New York at the top.
The system Man and the Earth is investigated by various disciplines starting from the earth and biological sciences upto physics, chemistry, economic, social, agricultural and technical sciences. The geographical sciences should try to keep
their central position due to their wide perspectives, both spatial (regional) and historical (genetic).
Globalpositioningsystem: an effective way to map a small area or catchment
The GlobalPositioningSystem (GPS) is an established method for establishing high accuracy horizontal and vertical control points over large areas. This paper compares different GPS methods with occupation times of 2 s, 2 min and 12 min using
