In the field survey of archaeology, huge amount of data are gathered through various methods such as taking photos, handwriting drawings and acquiring digital data like 3-D laser, and these data should be related to each other. However, it is difficult to relate these data together in present condition, because there are some differences in a format, a scale, and a precision. Therefore, a data management tool for archaeological field survey is being keenly demanded. In this study, we aim to develop the method for data management system, named "Geospatial data manager". This system is a comprehensive data management scheme based on photos to help archaeologist easily and quickly develop data product on the Web. And through this study we propose standard metadata type at investigation in archeology. Our system enables us to manage various data by attaching absolute location on maps and by relating with each other based on the qualitative proximity. With the absolute locating component, individual objects are given geometrical positions in a global space. And, the relative data connection component helps provide a relationship between data with hyperlinks. And also we publish and manage this system on the Web. Moreover, our application help elicit hidden context by raking up information on the relationships among data through the Web. Experiment in it based on the data of investigation of the world heritage of Tyre, Lebanon.
