Abstract: Space images started civil uses since Landsat satellite was launched in 1972 and were mostly utilized by government agents. The civil uses were soon expanded to many fields of science, engineering and education; nevertheless personal use of the space image is the goal of the application for the remote sensing satellite. The paper describes a study of combining a space image and the stories of the spots on the image. Part of the paper was the result of the assignment of the history course. It demonstrates an excellent personal use of the space image.
The authors live in an area called Jin-Shan-Miann (JSM) adjacent to Hsinchu Science-Based Industrial Park (SBIP). The SBIP, nicknamed Taiwan's "Silicon Valley", is famous with semiconductor, PC computer, and related high-tech industries. Many famous worldwide companies are located there, such as, Taiwan Semiconductor Manufacturing Company (TSMC) and Acer Inc. On the other hand, the JSM was bright in the past but is faded now. The authors collected the stories and the image of the spots of JSM and tried to connect the old history and true spots with a simulated ROCSAT-2 image. The five stories were collected about JSM including Jin-Shan Temple, Kang-Lun Temple, Cool Water Stream, Huangs' House, and the oldest tree of Hsinchu City. The area of interest was selected and cut out from an air-borne image. The resolution is re-sampled in two-meter to generate an ROCSAT-2 image that will be available in late 2003. Furthermore, the simulated image was value-added with overlapping, marking and annotating. Since the space image provides plenty of information of the spots and the connections between those. It is then an excellent medium in the near future for students or the public to recognize and familiarize the area where he or she lives.
1. Introduction
Space images started civil uses since Landsat satellite was launched in 1972 and were mostly utilized by government agents. The space images take advantages of continuous archive of long history, global coverage, latest timing, and wide size. The civil uses were soon expanded to many fields of science, engineering and education; nevertheless personal use of the space image is the goal of the application for the remote sensing satellite.
Taiwan started the applications of the space image since 1974 and receiving space images from space in 1994. For educational applications in Taiwan, some SPOT images were collected to introduce the landscapes of Taiwan by professors and journalists (Wang 1998c). A junior high school teacher used SPOT images as supplementary materials in her earth science class (Kueng, 1998c). The user community grew up very fast over the recent years. Consequently, National Space Program Office, the official space organization of Taiwan, proposed a space imaging satellite in 1997. A pilot project, called "Investigation on the Requirements and Applications of Remote Sensing Satellite", was carried on during September 1997 and February 1998 (ERL/ITRI 1998a). The requirements were surveyed among the local users for the first baseline of user needs. After intensive discussion, the system requirements were finalized and filed in the Request for Proposal for an open bid. Matra Marconi Space (Astrium) won the spacecraft, a satellite without the science payload, in 1999 after bid competition. The satellite development passed the system design review in March 2000 and preliminary design review in June 2000. The satellite is scheduled to launch in 2003. The main characteristics of the satellite are as shown in Table 1.

2. Jin-Shan-Miann
The Jin-Shan-Miann area is a community area rather than an administrative area. The Jin-Shan Temple is in the center of the area. It includes a big part of the present Hsinchu City and Hsinchu County. Most of the residences in this area are Hakkaness. T here are lots of historic sites in this little area, and five of them will be introduced later in this article.
