Research on embedded GIS based on wireless networks

With the rapid development of GIS, embedded technology and wireless communication technology, embedded GIS based on wireless networks becomes an active research area in the field of GIS. On the one hand, mobile embedded GIS enables users to enjoy spatial information service by wireless networks anytime and anywhere. On the other hand users can customize information at will so as to meet the requirements in different professional fields. The purpose of the paper is to propose a solution of embedded GIS based on embedded devices and wireless networks. The main contributions include a novel new system architecture and detailed function of each component. Besides, the method of data organization, the visualization of digital maps, and spatial data transmitting by wireless networks are presented. Based on our strategy, a practical system is developed to prove the validity of our strategy´. Experimental results demonstrate our strategy can meet the actual need of the visualization, querying, editing and analyzing of spatial information satisfyingly
