This paper proposes an efficient spatial data manager for map services in mobile environment. It is designed to provide interoperability and efficient performance at once. To provide interoperability and reusability, the spatial data manager conforms to international standards such as the OpenGIS Simple Features Implementation Specification for OLE/COM, OpenGIS Geography Markup Language (GML) Encoding Specification developed by the Open Geospatial Consortium (OGC). The spatial data manger exploits physical main memory using Address Windowing Extensions supported by Microsoft Windows to manage spatial data for efficient performance by reducing time to read data from disk on user's request. The format of the spatial data in main memory is target data (GML) to reduce conversion time from source data to it. Progressive transmission is also provided to reduce latency time by representing only received partial data for mobile environment without waiting whole transmission.
