摘要：Modern geographical information systems make it possible to integrate information from multiple sources in different forms for querying and analysing information. So the importance of geospatial databases is growing from day to day, and their applications extend beyond the traditional applications of geospatial databases and GIS. One of the most recent challenges is integrating geospatial data from heterogeneous sources with varied formats and positional accuracy into databases for GIS applications. Another research is required to integrate time into the databases because geospatial data and its applications are not always static. The aim of this study is to provide an overview of current status of researches and future trends in geospatial databases
