Airport detection is one of the most important research topics in the remote sensing application field. In the field,
majority of airport detection methods are designed based on different single resolution optical remote sensing images.
However, because of the RS data's limitation and algorithms' shortages, these methods are not likely to have a perfect
performance; inaccuracy and inefficiency are the two main drawbacks. In recent years, while much research of airport
recognition has been done on single resolution images, less work has been tried to study on multi-resolution and multi-spectrum
images together. Nevertheless, after many experiences, the latter method is proved available and attemptable in
our research. Based on the different characteristics of multi-resolution and multi-spectrum images, we try to design a
synthetical model which includes algorithms of structure feature analysis and spectral analysis. In the model, different
advantages of images and methods are combined to reduce influence of each other's limitations. Finally, an airport-detection
system is implemented based on the synthesis method.
This paper focuses on the designment and implementation of the synthesis model, enrich the research of airport
recognition and solve many problems. Section 1 provides an overview of the synthesis model. Section 2 discusses the
core algorithms of the method in detail. Section 3 demonstrates airport detention system and Section 4 concludes the
Daily works of Law Enforcement Bureau are crucial in the urban management. However, with the development of the
city, the information and data which are relative to Law Enforcement Bureau's daily work are increasing and updating.
The increasing data result in that some traditional work is limited and inefficient in daily work. Analyzing the demands
and obstacles of Law Enforcement Bureau, the paper proposes a new method to solve these problems. A web-GIS based
information management system was produced for Bureau of Law Enforcement for Urban Management of Foshan. First
part of the paper provides an overview of the system. Second part introduces the architecture of system and data
organization. In the third part, the paper describes the design and implement of functional modules detailedly. In the end,
this paper is concluded and proposes some strategic recommendations for the further development of the system.
This paper focuses on the architecture and implementation of the system, solves the developing issues based on
ArcServer, and introduces a new concept to the local government to solve the current problems. Practical application of
this system showed that it played very important role in the Law Enforcement Bureau's work.
