Design Method for Dynamic Map Symbols Based on RIA Environment

Abstract:

Although Geographic information system has just developed for decades, the course of its development is very rapid. The application and services of GIS technology have almost extended all the fields related to spatial information. Map, as the basis of GIS, its important position is self-evident. Map symbol is the language of the GIS map, which is the expression of the map content, the main medium of spatial-data information transferring, and an important feature differs from other images referring to the geographical environment. The function of Dynamic electronic map based on modern visualization tools, is far more superior to the traditional static map. Its expression is more rich and vivid, and introduces interactive operation into loading images, which enhanced the initiative and adaptability. The dynamic symbol is the basis of powerful visualization capabilities of dynamic map. With the support of the dynamic symbol, dynamic map is even more vivid and detailed. This paper is mainly about design method of dynamic map symbols based on rich Internet applications (Rich Internet Applications, abbreviation RIA). Take Flex as the case,which focus on the animation effect in Flex and achieves the dynamical substitution of point symbols on the map published by ArcGIS Server with ArcGIS API for Flex. Furthermore, look forward to the combined applications with web service.
