Conclusions, Limitations & Future Scope
The research brings to the forefront an important concept of utilizing multiple
web-based geodata sources and the possibility to get a master repository of
such databases integrated together. This paper lays down the basics of such
joining of opensource data tables that has been achievable by following
certain breakthroughs like first combining OSM with GeoNames and then
searching NE for place matching. This approach increased accuracy to almost
95-100 % which had not been achieved before. Joining of datasets requires a
