Description: Some server based database management systems implemented
        the OpenGIS Simple Features Specification for SQL. The OpenGIS
        specification defines two standard ways of expressing spatial
        features, the Well-Known Text (WKT) form and the Well-Known
        Binary (WKB) form. Both WKT and WKB include information about
        the type of the feature and the coordinates which form the
        feature. These systems (e.g. PostgreSQLPostGIS, MySQL, ORACLE,
        MSSQL) allow to store the topological features and the
        descriptive data in the same database. But these systems assume
        that the user needs permission to a running service or to
        install a server to use the spatial data. In some cases, it is
        useful if the user can use the database stored maps on
        different computers and platforms. The SQLite is a good choice
        for a portable database, it is platform-idendependent and there
        are some R packages to manage SQLite databases. Unfortunately,
        it has no spatial extension, but there is an SQLite extension
        for the SharpMap library. Following the idea of this solution
        this package was developed that may help the user read and
        write spatial features from and to an SQLite database. Each
        table with geometry field is treated as a layer. The tables
        contain the topological features in one geometry field in WKT
        form. For conversion of standard map files to SQLite table
        maps2WinBUGS can be used.
