- 초록
- Recently, we started the national project titled the development of automatic change detection and map composition techniques based on multidimensional /multitemporal geospatial data for efficient construction of digital national database. This project is funded by the Ministry of Land, Infrastructure and Transport of Korea. The key research framework of this project is to detect changed area from the multi-sensor data, extract the changed object and model, and update and manage the spatial database in consistency and timely manner. Among these, the geographic object needs to be modeled considering the level of detail (LoD) according to the application, and transition between LoDs should be supported. Prior to the development of LoD transition technology, we surveyed the research literature on LoD and classified them according to several themes.
