This paper dealt with the reflection spectrum and polarized reflection spectrum of 20 rocks in 2πspace, then get the model of reflection spectrum of rock surface in 2πspace. We measured the change of the reflection spectrum and polarized reflection spectrum according to the altering of the incidence angle, vertex angle, azimuth angle, bands, polarization. The results shows: the influence of incidence angle to the spectrum curve is very strong. And when the vertex angle is equal, the horizontal azimuth polarizes the rock spectrum, and elongates the circular spectrum in mirror direction, and the shape after distortion is much like ellipse. The polarization has influenced on the intensity that the rock spectrum reflected, but has no evident influence on the characteristics of wave shape of rock in 2π space. So we can describe the whole reflection spectrum characteristics (including polarization) of rock surface in 2πspace by measuring and calculating the value of e and p in several key directions.

An integrated information system (ERP system) of 1 tourism industry is proposed in this paper for the management of the planning of Mt. Emei and the relative industries. The authors also demonstrate the advantages of ERP solution, including its construction and functional realization in detail. The fusion of much spatial information in the ERP system is discussed and a spatial integrated information scheme is proposed.

In this paper the authors analyzed the data collection of seabed terrain, the influence factors on measurement precision and the data computation in time or frequency domain. In order to estimate the noise embedded in the received data, the structure and algorithm of characteris tic matching filter based on the entropy concept is developed and discussed in detail. It is shown that the noise data can be removed effectively and the high precision seabed terrain be simulated by the filtering method.
