Libgwmodel: a Fundamental C++ Library to Develop Geographically Weighted Models

The increasing popularity of geographically weighted (GW) techniques has resulted in the development of several software packages. Their ongoing updates and enhancements always require extraordinary efforts. In this study, we introduced a fundamental C++ library, namely libgwmodel. With its updates and maintenance in the future, all the associated products could be uniformly maintained and upgraded. Moreover, its development will greatly facilitate the further achievement of more GW models or tools, even from different teams, so as to form a comprehensive foundation for further development and extensions of GW models.
