Frontiers and Trends on Geo-information Science

In each branch of the geo-information science,there are some frontiers.The frontiers of the geo-information philosophy involve the ontology of digitized world,geo-information flow and geo-spatial epistemology,methodology of the geo-information science.Those of the geo-informatics include transit mechanism of geo-information,cognition of geo-spatial information,extensions of geo-information representions,uncertainty in geo-information,geo-spatial relations,geo-spatial scales,interoperability of geo-information,etc.Ones of the geo-information technology consist of the integration and amalgamation of the geo-information,spatial analysis and modelling in GIS,integration of the geo-information technologies,visualisation of geo-sciences,virtual reality,interoperability of GIS,distributed computing and object-oriented technology in GIS,etc.At present the information infrastructure and digital earth,foremost hot spots in the geo-information science,are the most important geo-information engineerings.In future,the development of the geo-information science will emerge some characteristics as follows: 1) theoretical and projectional researches getting more and more important; 2) subject intersections becoming more and more extensive; 3) standardization of the geo-information and information technology; 4) information representions getting more and more multi-dimensional; 5) integration and intelligentization of the geo-information technology; 6) networks of the geo-information engineerings and socialization of their applications becoming more and more obvious.
