With the development of remote sensing techniques, RS had become an effective way to do the disaster monitoring and assessment. Nowadays, remote sensing plays an important role in disaster mitigation. But the methods to produce the main product of remote sensing data - image maps, are very complicated, and varies work flows, lot of image processing and operations are included. The requirement for...
Based on a portable device, highly integrating Remote sensing, GIS and GPS technology, using Embedded development, the mobile GIS system specially for forest resources inventory hardware was developed. The paper deeply discusses the composition of the system, key technical problem which it has solved, and current status of the practical application of the system all over the nationwide. The research...
This study aims at revealing how land use and land cover change in the typical watershed (Luoyugou Watershed) of Loess Plateau over past 20 years. Based on the remote sensing imagery data and topographic map, a four-stage (1986, 1995, 2001 and 2008) spatial data base was established with ArcGIS software. Demographic data, agricultural economic data and other auxiliary data were collected from national...
The spatial distribution of disease epidemiology has always been the hotspot and difficulty, information technology and GIS technology have been widely applied in epidemiological studies, along with the continuous deepening of the disease spatial analysis development. In this paper taking H1N1 flu as the research object, given that China and Shandong Province, the number of infections and deaths'...
Using 30 m resolution DEM to extract the elevation, slope, aspect, amplitude and water information of Nu People and Lisu Peopl's residential area on the ARCGIS software platform . The settlements, and water information were provided by National Geographic 1:250000 basic geographic information and data. All of this information was used for spatial overlay analysis to obtain the quantitative relationship...
