Design and Implementation of Integration Framework for Terminal-Oriented Mobile GIS Data Collection

Based on its characteristics of quickness, portability and friendly interaction interface, mobile GIS for spatial data collection has become an important developing direction of GIS as well as a major method for GIS data collection. However, the current mobile GIS data collection studies mainly focus on the implementation of mobile calculation but overlook the integrative mechanism for mobile data collection. Based on the background information that mentioned above, this paper launched a design and implementation research on integration framework for terminal-oriented mobile GIS data collection. The integration framework mainly includes two parts: first, a version-based data distribution and retrieval mechanism; the second, a data transmission mechanism called offline transmission environment which applies to different data transmission modes between server and mobile terminal. Through Nanjing Municipal Facilities Collection System, this paper gives a detailed description about the implementation of this proposed integration framework to validate the feasibility and validity of it.
