Topographic maps are essential data for various applications in spatial area. These maps provide GIS a rich visual illustration of the area. Traditional topographic maps are produced with multiple scales because end-user requirements vary. The concept of "feature" has been incorporated through recent technological developments. A spatial object of a map (with a particular scale and time) can thus be recorded as a spatial representation of a particular feature. A feature-based topographic database can provide the essential "spatial description" component for a particular feature. However, a spatial phenomenon may be represented differently in maps of diverse scales. A feature-based topographic database must provide an appropriate spatial representation of existing topographic maps with multiple scales. This study analyzes existing multi-scale representations of a particular feature in a topographic map and proposes a framework for a feature-based topographic database. This database can effectively maintain necessary links among all of its related spatial representations. This link is implemented by a developed standardized identifier. This identifier can recognize a feature by the spatial or non-spatial properties of a feature. All spatial representations of a feature at different times can be linked using the developed standardized identifier and queried using the proposed method. This study presents the critical parts of a feature-based topographic map database, including the design of the identifier and the linking of the spatial representations of a feature. A prototype is developed to illustrate how a scaleless topographic map database operates.
