Abstract
In this paper, a light mobile GIS framework is proposed which is based on J2ME and mobile scalable vector graphics (SVG). Firstly, in this framework, it gives a general mobile GIS framework, the specification of mobile SVG, the specification of mobile XML, and the rules for spatial data organizing. Secondly, all kinds of GIS code rules are defined, how to manage map layer in SVG is defined, all kinds of GIS’s object can be described in SVG and DOM of XML. And finally, in distributed environment, based on SVG, JAVAME and related technologies, a light mobile GIS platform is implemented, and the platform is applied to the Daqing oil field. In the oil field, many oil fields are remote from the company, some oil fields are not covered by wire-network, in this case, remote oil well production data can be transmitted by means of wireless network, In this case, the light mobile GIS platform can be used to not only transmit production data, but also locate the interested objects. The practical application shows that this light mobile GIS platform is primarily able to satisfy practical applications in speed and LBS.
