Exploring the significance of geo-tagged information of a satellite image and associated shadow information in the image to enable man-made infrastructure dimensional characterization, in this paper a novel approach has been developed to estimate the height of a man-made structure accurately. Our proposed method applies shadow detection and shadow feature along with geo-tagged information retri...

In the Brazilian Amazon, where the forest sector plays a particularly important role in the economy [1], a better understanding of stem volume distribution is necessary to support those who manage forests for wood production during strategic planning, resource allocation and operational decisions. In addition, international agreements are underway for developing global observation systems to as...

In order to explore high-dimensional data spaces and to gain insight into the underlying geoprocesses suitable tools are needed. Especially interactive, computer-generated representations enrich our perception, so that complex phenomena can be comprehended intuitively. Although several helpful visualization techniques are available today, there is a growing demand for more advanced tools and st...

A Data Warehouse is a centralized repository of data acquired from external data sources and organized following a multidimensional model (Inmon, 1996) in order to be analyzed by On-Line Analytical Processing (OLAP) applications. OLAP tools provide the ability to interactively explore multidimensional data presenting detailed and aggregated data. The results of analyses are the basis of strateg...

The international community is currently undergoing an incremental but definite shift of the economic and strategic centers of gravity to Asia. The fundamental change has been brought about mainly by newly emerging powers like China and India. In the Asia-Pacific region, this geo-strategic reconfiguration has led to a changing balance of power and influence between the United States and China i...

In this paper a project to convert the content of strategic spatial policy documents to a digitally exchangeable format is described and discussed. The conversion is based on a purposely-designed information model in which geo-statements – policy statements with a geographic reference form the elementary objects. These objects have to be identified in the reports and linked to policy maps for w...

metals used in everyday life are produced from ores occurring in the earth’s crust. geological processes are known to concentrate minerals to form ores of economic value. mineral processing engineers concentrate these ores by mechanical and physico-chemical methods while the extractive metallurgist extracts the metals by chemical means.
