Recently, the utilization and need of spatial information have been continuously increased with increasing amount of information in accordance with the urban expansion, such as various changes in the industrial structure and economic development. In spite of increasing of the demand and utilization of spatial information, the speed of spatial information update cannot meet the trend of change of land use. Therefore, it can be a very important requirement that the latest spatial information should be maintained.

It is difficult to update the spatial data and to maintain the newest information each time because it contains a problem of efficiency and economy in time and costs. Collecting spatial data in a conventional manner is also limited to reflect a real-time information service for the change of land use. Hence it need to find efficient and effective way for improvement of the quality of the data service.

As a new technology to overcome these limitations, Unmanned Aerial Vehicle System (UAVS) has been recently applied to build a three-dimensional spatial information rapidly and accurately by using an Unmanned Aerial Vehicle (UAV). The UAV has many advantages, for example high-resolution images, economic cost, and having less of weather affect, than a satellite measurement and an aerial survey. Especially, the UAV provides high resolution of less than 5cm for a repetitive task. However, its technology is at an early stage and requires continuing research to make better use in terms of a photo survey

In this study, the UAV system in the survey and spatial information field has been performed for quality analysis and geometric analysis by basic spatial data. The study also analyzed the data capturing feature in UAV system dependent on ground control point and reviewed compatibility with conventional digital photogrammetric system by DPW. For shooting method, data processing obtained from UAV and accuracy analysis of spatial information production were carried out.
