  • Relational Geographic Databases
    Relational Geographic Databases Dehua Zhao1, Byunggu Yu (corresponding author)1, Bong H. Hong2, and Dan Randolph1 1Department of Computer Science University of Wyoming PO Box 3315 Laramie, Wyoming 82071, USA phone: (307) 766-2440, fax: (307) 766-4036 [email protected] 2Department of Computer Science and Engineering Pusan National University San 30, Jangjeon-dong, Gumjeong-gu, Pusan, 609-735, Korea phone: +82-51-510-2424, fax: +82-51-517-2431 [email protected] Abstract. This paper proposes a generic relational-database schema that can efficiently accommodate various types of GIS data. The proposed schema complies with the OpenGIS Simple Features Specification for SQL developed by OGC (OpenGIS Consortium) and can be used for any geographic application whose geographic objects are represented based on 2D geometry with linear interpolation between vertices. The generic schema that we propose in this paper makes it possible to automatically generate a relational database schema for any existing or new 2D GIS dataset. This facilitates the migration and deployment of GIS data in well-established relational database environments. Consequently, sharing and integrating GIS data become much more feasible. In addition, since any relational database management system (DBMS) can be used, developing a GIS application system on existing GIS data is facilitated. We verified the proposed schema and automatic schema generation mechanism by developing and testing a relational geographic information system. Keywords. Geographic Information System, databases, relational databases, schema design. 1 Introduction Just a few decades ago, paper maps were the principal means of synthesizing and representing geographic information. Paper maps are limited to manual manipulation and fail to meet the increasing demand for interactive manipulation and analysis of geographic data.
