Design And Implementation Of Geographic Information Visualization System Based On Android Platfrom

With the rapid development of computer technology and network communication, geographic information system has developed into a multidisciplinary which acrossed multiple fields such as geography, surveying and mapping, resource management.lt contained deskstop gis,web gis and mobile gis.Mobile gis got rapid development because of its portability and real-time online works. To realize the visualization of geographic information, this topic combained surveying and mapping data and geographic information together and displayed the statistics multi-dimensionally.The followings are the main content of the paper.1. The data source. By analyzing the data of surveying and mapping, we standardized the data, set up the connection between the data which provided convenient to unified management of the system.2. The design principles. We used a hierarchical design which combined with several design patterns and made the process optimized through the analysis of business requirements. Eventually we realized the extensible and modular software architecture.3. The map visualization. This topic completed the custom maps and location based services, and designed map layers based on ArcGIS API. We made improvement in some aspects such as the dot information, partition information and color rendering, through that the data showed more abundant.4. Project information visualization. To highlight the details for data visualization demand, we classified the query operations by means of histogram and chart to show special query information. This system facilitated the data access and contrast based on the research of the data visualization technology. At last, we test the system and the results showed it operated normally and smoothly. The results meet the designed requirements.
