The study of adaptive rendering model for custom map symbol on different GIS Platform

Map symbol is considered as language of map, the design and implement for map symbol in different GIS platform were different. Due to different mechanisms, the map symbol designed on GIS platform was hard to reuse in others. Custom symbols difficult to meet the requirements of a variety of GIS platforms. This paper studied the process of geo-visualization, analyzed the coupling method between GIS platform and custom map symbol, then proposed adaptive rendering model, and finally the model was verified by implementing the same custom map symbol in different GIS platform.
