Li Yue, Wang Yanhui. SVG based representation and compression of spatial data in LBS[J]. Journal of Image and Graphics, 2011, 16(5): 903-908. DOI: 10.11834/jig.20110529.
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. The test result showed that SVG based method is appropriate to represent geodata in LBS
and the improved method to compress SVG based data is better than traditional method
in which the feasibility of the solution is validated.
