Geography Information System (GIS) and Geography Teaching Material

GIS technology applies geographic science with tools for understanding and collaboration. It helps people reach a common goal: to gain actionable intelligence from all types of data. GIS integrates many different kinds of data layers using spatial location. Most data has a geographic component. GIS data includes imagery, features, and basemaps linked to spreadsheets and tables. Spatial analysis lets you evaluate suitability and capability, estimate and predict, interpret and understand, and much more, lending new perspectives to your insight and decision-making.

Design and Implementation of Three Dimensional Fire Safety Household Registration Management System

With the development of economy and the acceleration of the urbanization process, city fire accidents, casualties and property losses were more and more serious. Fire supervision was not strict and rescue was not timely were the main reasons for the fire and disaster aggravated. This paper used the basic principle of fire safety theory, took ChaoYang District building group as an example,combined with Visual C# and SuperMap Object.Net component GIS platform and realized the Three Dimensional FSHRMS (three dimensional fire safety household registration management system). This system mainly realized the information management of city group construction, fire protection, household register management, three-dimensional fire simulation and other functions.

Research on Groundwater Pollution with Contour Line Realization Methods Based on Monitoring Data by COMGIS

Groundwater pollutions visualization can be come true by interpolation with monitoring data, which is very helpful to know the situation of regional pollution. In this paper, the spatial database is constructed by GIS software, it is used to manage the monitoring data dynamically, adopting the component GIS, the monitoring data can be easily loaded into the developing environment, by the contour and contour line method, the contour line of groundwater pollutants can be acquired, which is very important to visualize the regional pollution situation.

Design of Electric Power System Based on Component GIS

GIS is getting more attention in the application of electric power system. This article mainly focuses on the electric GIS system based on the practical need in the electric system. This electric GIS system is composed of three subsidiary systems, among which PDA may transfer data collected by the inspectors to GIS general management and control system through GPRS, design the Geodatabase and system functional modules which accessed by multiple users simultaneously with C/S model, to achieve the automation in the information sharing and collaborative work.

The Quantitative Evaluation of Coal Seam Stability Based on Component GIS

The stability of the mining is important for coal, and stability of the current status of coal was analyzed, selecting appropriate indicators that evaluate the importance of stability of the coal seam is so significant. Using GIS Spatial database to achieve a unified data management for spatial data and attributes, and analyze of coefficient of variation of coal thickness and correlation dimension of coal thickness, and use of these two indicators of a coal mine in the coal seam to analyze stability evaluation. Finally, developed stability assessment system of coal based on component-based GIS MapX. The results show that quantitative evaluation of the stability of the coal is reliable, can provide a theoretical basis for coal mining.
