In this paper, we would like to study environmental change and living impacts on resident lives before and after Central Taiwan Science Park (CTSP) started its construction in 2003. To collect the information of concern, we interviewed people who live around the CTSP, including Situn District and Daya Township, by dispatching students who brought questionnaires designed in this study to visit the residents home by home. The surveyed data are recorded in a database and analyzed by using two software tools, iData Analyzer and ESIR ArcGIS which are data mining tool and GIS packages, respectively. The former is used to find out the connotative information embedded in raw data so users can catch the deep knowledge from what we have collected, whereas the latter is employed to spatially present the raw data and analyzed data on an electronic map from which users can realize how the data are spatially distributed and what their spatial semantics are. After mining the data, we found that people living in Daya Township have no significant changes on their everyday lives. But Situn District has been quickly developing. Most employees of the CTSP and their families come to live in Situn since this district is located on the side near Taichung city which is a huge modern city with plenty of people and living facilities, e.g., restaurants, supermarkets, hotels and others, which have been prosperously constructed in the past few years in Situn District. Even this, from some special viewpoints, we can see that Situn's development will soon approach to a bottleneck due to its limited hinterland. The consequence is many people will move to Daya which will then migrate to a busy and business town from a current quiet agricultural town. During the interview, we did not record the interviewed people's GIS positions. Thereafter, we spent a lot of time to locate their addresses one by one on the electronic map. In fact, if we can develop a software tool to automatically record the position, including longitude and latitude, for each interviewed home/resident, it would be easier for us to show up the addresses by sending the position information to a GIS system. Therefore, in this research, we develop a positioning system by employing a GPS. When a visitor finishes his/her interview to a person and steps out the house, what he/she needs to do is pressing a few key buttons on his/her notebook computer. This will record the geographical position of the house to the corresponding record in the database. The tool can also transform the latitude and longitude to TM2 which is the format that our GIS system provides. Besides, for the team members' convenience, the tool saves the data/file in TXT format so the data can be conveniently invoked by Microsoft Office, ESRI ArcGIS and other software tools without any transformation. To further the utilization of the positioning and GIS tools, operation guides for them have been written.
