Implementation of a smart map using spatial oracle

Geographical Information Systems (GIS) are special types of information systems managing geo-spatial data. The GIS is used to manage geo-referenced information and it represents spatial position of any location into digital map. The GIS also facilitates the user to retrieve spatial information easily using a lot of geographic functions such as data integration, mapping, and overlaying, buffering, projection etc. In the traditional GIS, layer wise data extraction is difficult as it is not followed layerwise data storing. In this regard, our system is able to extract spatial data layer wise from database according to the user's interest. It is also able to work with both spatial data and attribute data (non-spatial data). Spatial data describes the locations and shapes of geographic features like roads, buildings and streets while attribute data describes the characteristics of geographic features (like name, type etc.). In this paper, we present an approach to implement a map of a town considering the layers (road, building like administrative office, health center, educational organization etc.) using spatial database and map-viewer.
