Integration of Heterogeneous Geospatial Data Based on Middleware Technology

摘要

The diversity of the geospatial data format has led to the difficulties in data sharing. In this paper, three popular modes for integrating heterogeneous spatial data are analyzed. Aiming at their weak extensibility, a method of exchanging data format based on middleware technology is proposed. What's more, this method can be extended freely. By establishing an internal format and using the independent interface designed in this paper, we can realize the exchange among different formats. Through this method, we can resolve the data-sharing problem cross several typical GIS platforms, and make the integration of heterogeneous data freely and conveniently.
