Abstract

Mobile GIS, a novel intercross research field integrating modern mobile computing techniques with geographic information science, has attracted more and more researchers in developing and deploying new techniques in mobile GIS. Efficiently exploiting the limited resources of mobile device, treating and manipulating geographic data using a uniform data model, and guaranteeing the dataset quality from field data collecting, require an appropriate mobile GIS architecture and an efficient underlying spatial data engine support. In this paper, we discuss the popular architectures of mobile GIS and present our approach: Embedded Lightweight Spatial Data Engine, named ELSDE. With efficient integration of embedded RDBMS, spatial index framework, binary topological predicates and the OpenGIS simple feature data model, ELSDE can provide a robust underlying spatial database like support for various higher-level mobile GIS applications.
