1. On the basis of the analysis of the background, progress and methods of land use / cover change (LUCC) research on the world, the main contents and methods in this paper is proposed for focusing on spatial-temporal land use data capture and quality control, and land use / cover change (LUCC) modeling and analysis in Jiading district, Shanghai.
Aiming at a great deal of data existing in modern logistics enterprises, it provides how to use data mining technology to mine effective data so as to help decider to make correct and effective decision.
Besides, on the base of researching popular metadata criterion home and abroad, the estuarine and coastal metadata content criterion is built in this paper, and browsing and querying core metadata functions have been finished, which can help user understand information correlative with data, and help them use data effectively.
This system use data relation character, data lock, main-assistant table , dynamic modification of SQL technique as sustentation, achieves the data storage , data sharing, statistic, report print , data exchange function in MDI windows , multi-table operation forms. A two-class purview method is used to endured the data safety and credibility.
On the basis, use data miming technology to design an analysis platform for the supplier's behavior of the ERP system, and specified the platform's architecture, function module and the technology that be used.

We use data on open star clusters (OSCs) from the Homogeneous Catalog of OSC Parameters to determine some of the parameters of the spiral structure of our Galaxy: the pitch angle of the spiral arms
Numerous measurements for a small and varying number of background neutrons in the trap make it possible to extract and use data for determining the mean neutron lifetime.
Cases of alcohol or substance misuse and dependence were identified through standardised interviews with patients and keyworkers, and socio- demographic and in-patient psychiatric service use data were also recorded.
To evaluate segmented reconstruction algorithms for spiral multi-slice computed tomography (MSCT) that use data from two cardiac cycles to improve temporal resolution (τ) for imaging of the heart.
Subdivision of polygon parcel in land-use data generalization
Energy data-base is not only for data store or printing energy report forms, but also for analysis, prevision and optimum math models. The paper would discuss how to use data-base for optimum calculations.
To improve remotely sensed imagery classification accuracy is one of the main topics in the field of remote sensing application research. Integrating geographic data, interpretation knowledge used by expert, a new method was proposed. In classification procedures, DEM, slope and previous land use data were used as well as imagery, knowledge was represented by rules. The method has been approved to be effective to improve the classification accuracy compared to a Maximum Likelihood Classifier.
