An optimal and integrative tsunami warning system is introduced that takes full advantage of remote sensing and geographical information systems (GIS) in monitoring, forecasting, detection, loss evaluation, and relief management for tsunamis. Using the primary impact zone in Banda Aceh, Indonesia as the pilot area, we conducted three simulations that showed that while the December 26, 2004 Indi...
Small-area population estimates for a non-census year are essential for supporting a wide variety of planning processes. Many demographic or geographic-informationbased models have been developed for generating small-area population estimates. Little research, however, attempted to integrate these two types of models to achieve a better estimation. This study explores the feasibility of incorpo...
Several structural changes, in particular the introduction of Bachelor and Master programmes at Universities in several European countries, have an important impact on higher education and indirectly on post education, also in the field of GIS, Photogrammetry and Remote Sensing. Some of the underlying concepts of these changes favor the complementary use of E-Learning materials, especially in f...
Landscape ecology as a modern interdisciplinary science offers new concepts, theories, and methods for land evaluation and management. One main part of landscape ecology is describing patterns in the landscape and interpreting the ecological effects of these patterns on flora, fauna, flow of energy and materials. Landscape studies require methods to identify and quantify spatial patterns of lan...
This study examines the temporal and spatial changes in land use as aconsequence of rapid urban development in the city of Beijing. Using a combination oftechniques of remote sensing and GIS, the study identifies a substantial loss of plaindryland and a phenomenal expansion of urban construction land over the recent decade.Geographically, there is a clear shifting of urban construction land fro...
this research has been carried out with the aim of the determination of the land-use changes of the forests in the protected area of arasbaran. the determination of the changing points and the factors influencing these changes by the use of gis and remote sensing are the main aims of this research. accordingly, the satellite pictures pertaining to the years 1987 and 2005 along with other necess...
Land use change is one of the most important factors of global environmental change. So, understanding and predicting the causes, processes and consequences of land use and land cover has become a major challenge. The Remote Sensing and Geographic Information System (GIS) technologies can be used effectively to detect and quantify of land use changes and its effects on the environment. The pur...
