Nowdays the need of modeling a real world using computers leads to increase the importance of GIS. Moreover, the wide spread of the Internet service has brought about Web GIS Development. Especially, the tuning of Web GIS system has a crucial role in improving the performance of high resolution image Web GIS system. Thus, this study provides a variety of ways to improve the performance of high resolution image Web GIS system. We have tuned IBM AIX operation system, Oracle, ArcSDE in the database level and Tomcat, ArcIMS in the application level. What is more, we propose ways of coding which can have a positive impact on performance. As a result, the proposed methods guarantee high resolution image Web GIS system to improve performance.

Spatial information and smart phone technology have made innovative improvement of daily life. Spatial and geographic information are in practice for various applications. Especially, spatial information along with information and telecommunication technology could create new contents for providing services for convenient daily life. Spatial information technology, recently, is not only for acquiring location and attribute data but also providing tools to extract information and knowledge systematically for decision making. Various indoor applications have emerged in accordance with demands on daily GIS(Geographic information system). This paper aims for applying spatial information technology to support decision-making in shopping. The main contents include product database, optimal path search, shopping time expectation, automatic housekeeping book generation and analysis. Especially for foods, function to analyze information of the nutrition facts could help to improve dietary pattern and well-being. In addition, this system is expected to provide information for preventing overconsumption and impulse purchase could help economical and effective purchase pattern by analyzing propensity to consume.
