The work present in this paper focuses on using CBERS imagery data to acquire some information such as land use/cover change (LUCC) by means of remote sensing and GIS and to find out an appropriate classification method to CBERS imagery by applying and comparing some classification methods. CBERS CCD imageries of Xuzhou city in 2001, 2005 and 2008 were classified by using decision tree classifier,...
Based on the analysis on Countrywide Railway Operation Simulation System, the logic model which is on the basis of Data Flow Diagram (DFD for short) has been put forward. The simulation analysis on the whole system has been divided into Section I and Section II. Based on the Train Operation Diagram Data, Section I will transform the data format, obtain the simulation data, realize the simulation,...
Sustainable development is regarded as the common goal of development by all the countries of the world. There are many approaches on evaluating the level of regional sustainable development. In this paper, back propagation artificial neural networks and GIS were applied to evaluate the levels of the sustainable development of 17 cities in Shandong province. Firstly, the writers choose 28 indexes...
Taking Shandong province as an example, the paper put forward the determination method of regional development axis and their importance and levels based on pole-axis theory. Firstly, the writers selected four regional development axes according to the conditions of choosing regional development axis, and then analyzed the ranges of the 4 axes and the cities and towns in the ranges with the method...
Direct Solar Radiation (DSR) is one of the most crucial weights of Solar Radiation, and its quantity calculation is very complex due to the influences of local topographical factors and terrain inter-shielding. DEM data as a representation of the complex terrain and multiplicity condition produces a series of topographic factors such as slope and aspect, etc. Based on DEM data and meteorological observations,...
Glaciers and lakes on the Tibetan Plateau play an important role in the earth's climatic system. The technologys of remote sensing and Geographic Information System (GIS) are quite efficient for us to analyze the status and fluctuation of glaciers and lakes. In this paper, the typical glaciers and lakes variations throughout the Tibetan Plateau are investigated by analyzing the datasets from aerial...
Highways are very important to Tibet. The Sichuan-Tibetan Highway was selected as the test area in this paper. There are many geological disasters, such as landslides, rockfalls and debris flows etc., occur frequently on the Sichuan-Tibetan Highway, which does great damages to peoples' life and property. Therefore, mastering the geological status is quite essential to design and maintain the Sichuan-Tibetan...
