Due to the geological complexity of the wide reservoir area, reservoir leakage problem has been the subject of Research in Water Resources and Hydropower Engineering. In recent years, the development and application of GIS (Geographic Information System), remote sensing technology and three-dimensional (3D) technology, have provided a powerful tool in analysis of the reservoir leakage problem. Based on the 3D remote sensing image visualization system created with remote sensing technology, GIS, 3D technology, this paper studies the leakage problem of a reservoir. By analyzing the terrain data, we can find the might existing leaking channels combining, combining lithology, geological structure and hydrogeological conditions. Then calculate the leakage quantity to evaluate the reservoir leakage. With the characteristic of accuracy and timeliness, the system will play an important role in preliminary analysis of reservoir leakage problemas well as forecasting decision making.

Hyperspectral Image Compression

With the development of Aerospace remote sensing technology, the hyperspectral remote sensing technology is widely applied in earth resources detection, environment investigation and military reconnaissance, etc. It is different from multispectral image, hyperspectral image spectrum period is as many as dozens to hundreds of band, with high resolution, large amount of data, corresponding to the data transmission problem, so the hyperspectral image compression is become necessary. In this paper the vector quantization algorithm is applied for hyperspectral image compression, first convert the three dimensional hyperspectral images into two dimensional pixel vectors, and then applied the vector quantization on the transformed pixel vectors. The experimental results show that the algorithm not only has better compression ratio, and can effectively save image spectrum section characteristics, which is a kind of efficient three-dimensional compression method.

Submarine pipelines must be designed to resist wave and current induced hydrodynamic forces especially in and near the surf zone. They are buried as protection against forces in the surf zone, however this procedure is not always feasible particularly on a movable sea bed. For this reason the characteristics of the sediment transport on the construction site of beaches should be investigated. In this investigation, the application of the remote sensing method is introduced in order to determine and observe the coastal morphology, so that submarine pipelines may be protected against undesirable seabed movement.
