The Theoretical Research of Spatial Information Service Model

this paper research on spatial information service laws of development and application from angle of model and put forward the basic conception of spatial information service model basing on information service model. It presents a complete structure of model, and detailedly explains elements, the main characteristics and principles of interaction. Consider that the reciprocity between the various elements is the main inner factor which can produce a variety of different services type, and thus lead to different spatial information services with a variety of different forms. At last this paper accord to the relationship between the inner factor and elements to bring forward the abstract services classification results which currently can cover almost all the spatial information service types, and give theoretical support.

The Application Practice of Geography Information Technology in Popular Science Area

In this paper, it mainly research on the application of geography information technology in the popular science educational fields. It applies the space-time attribute and the graph visualization technology into the popular science knowledge creation, establishes the space-time information model of the popular science knowledge, and combines with the digital earth technology to make information of popular science to be expressed and exhibited in the method of graphical visually. It improves the accessibility of the popular science knowledge, and realizes an new method to popular science knowledge.
