Abstract:
An XML-based description language of distributed geospatial data modeling and visualization—distributed spatial data markup language(DSDML) is presented,to give support to spatial data integration and shareing of popularized WebGIS platforms,which facilitates users' personalized applications.We expand the applications architecture,functions,and grammatical rules of DSDML in detail,realize a DSDML data parser based on SAX model,make experiments on Google Earth and GeoGlobe platforms,and implement seamless integration between DSDML and Google Earth or GeoGlobe.
