With the development of remote sensing dynamic monitoring technology and GIS spatial analysis, land use/cover change is the important areas of today’s global change research. It has not limited to the number and structure of land use changes in the quantitative research, but increasingly on the spatial and temporal patterns of land use change and

The process of obtaining the changed information of the earth by making use of multi-temporal satellite images is called change detection. According to the level of analyzing image, the change detection algorithms can be divided into pixel level class, characteristic level one and target level one. According to the mechanism of processing data, they can

The main purpose of image registration is to realize the process of geometricallyoverlaying two or more images of the same scene which are taken at different times,from different viewpoints or by different sensors. Remote sensing image registration isa crucial step in many image analysis tasks. It is popular used in environmentsurveillance, information fusion, machine vision,

With the development of global economy and the improvement in oil demand, theoffshore oil transportation and offshore oil exploration have become more and more busy,which increase the likelihood of marine oil spill. In recent years, marine oil spill is aserious threat to the sustainable development of the marine environment and coastal citieseconomy. More and more

Rough set theory, proposed by Pawlak in the early1980s, can be used to analyze andprocess imprecise, inconsistent and incomplete information for data analysis. The rough setdata analysis uses only internal knowledge, avoids the external parameters, and does notdepend on the previous model or assumptions such as the probability distribution of thedata method, the membership function

Vegetation is an important part of both the ecosystem and the ground cover. And vegetation is an important character of reflecting the earth’s surface. Vegetation plays a vital role in global change. It’s also an important parameter that can characterize and evaluate the ecosystem. The change of vegetation coverage indicates the changes of global and

Objective, timely, accurate getting crop growth information has important significance in guiding the crop development scientifically. VI (vegetation index) calculating LAI (Leaf Area Index) is one of the main trends of monitoring the growth by remote sensing at present. LAI can reflect crop growth and development to a certain degree. VI is the most immediate
