碩士 === 國立政治大學 === 地政研究所 === 99 === With the advance of technology, the management of the state-owned property has been shifted from using map and book to information-based management for some time. However, the property management system today can only get hold of the management of cadastral property information and property registration of producing agencies, yet the cadastral map is not able to integrate with the current land utilization and other spatial data to illustrate the location and to analyze spatial distribution of the lands or buildings. And the fact that cadastral maps cannot be updated in time to grasp the latest alterations has resulted in ineffective management and utilization of state-owned land and arbitrary occupation was not uncommon. It has been fifty years since the operation of the Canadian Geographic Information System (CGIS) in 1960s. However, in the early stage, the working platform were mainly expensive workstation computers, and the prices of hardware and software were so expensive that only the government or large research institutions could afford. Therefore, GIS had been used only for special purposes; the pubic had no access to enjoy the benefits of GIS. However, from the development of the past decade, user interface as well as the function of hardware and software has made a great progress. At present, International Organization for Standardization (ISO) and Open Geospatial Consortium (OGC) are separately dedicated to developing geographical information standards and they have launched many standards regarding the description and application of geographical information respectively. Much effort on the integration and the circulation of our National Geographic Information System (NGIS) sees that the threshold of GIS development has been reducing and its circulation of data also has considerably raised. Therefore, this research attempts to combine OpenGIS, Free Software and Open Source Software with Google Earth, a platform that covers a wide geographical resource, with the most economical and realistic approach to integrate cadastral maps, topographic maps and present-day photos with the data of land and building management, and related geospatial data such as base map and topographic maps, etc. By using graphics and geographic analysis functions of GIS, it can support the management of state-owned land and buildings.
