SVG based representation and compression of spatial data in LBS
LBS中基于SVG的空间数据表达与压缩

It is known that how to organize effectively geodata of mobile device in LBS(location based services)are organized ineffectively.So after the existing solutions are compared and extended in the paper,a new SVG(scalable vector graphic) based solution is provided to represent and compress spatial data.Then the key technologies in the fields of SVG data representation and compression are researched and resolved,in which the improved compression method combined simplified SVG representation and GZIP compression...
