Integration of Gis and Eos for Environmental Survey

چکیده
With the implementation of Earth Observation System (EOS), various technologies related to Earth Observation (EO) have been dramatically improved and extensively used. Geographical Information Systems (GIS) has also been developed greatly in recent years. Very few researches, however, have been done to integrate GIS and EO. Through analyzing some problems in the application of existing EOS and GIS, this paper presents a conceptual model on how to integrate GIS with various EO technologies. Based on the model, this paper provides a scheme to integrate GIS, RS, GPS and various airborne survey systems including multi-channelγ spectrometer, airborne magnetometer, and SO2, O3, NOx and aerosol detector. This scheme has been tested on Qinshan nuclear power station and its surrounding areas. From our fieldwork, it has been proven that the survey result is consistent with the scheme. This integrated system can also be applied to investigations of resources and environment, environmental surveys, geological explorations and disaster evaluations.

Selection of suitable sites for wind power plants is one of the most important decision on wind resources development. Site selection for the establishment of large wind power plants requires spatial evaluation taking technical, economic, and environmental considerations into account. This study has applied a combination of PROMETHEE and Fuzzy AHP methods in a geographical information system en...
متن کاملVLE Properties from ISM Equation of State: Application to Pure and Mixture
In this paper, the vapor-liquid equilibrium (VLE) properties of polar and nonpolar fluids are modeled by the use of a statistically-based equation of state (EOS). The equation of state used in this work is that of Ihm-Song-Mason (ISM) EOS. An alternative approach is to revise the isothermal integration on liquid. In this respect, a temperature-dependent revision factor b (T) is introduced to th...
