Development of Mobile Information Collection System Based on IServer

Abstract

Data is the "blood" of GIS. GIS focuses on data input, analysis and output, so data collection is particularly important. Traditional surveying and mapping has some shortcomings, such as backward equipment, low accuracy of data acquisition, low acquisition efficiency, and high cost of manpower and material resources. In the information collection of modern urban planning, traditional surveying and mapping has been difficult to meet the needs of data collection. At the same time, the emergence of various mobile intelligent devices and the increasingly mature development of related software and hardware make mobile terminal information acquisition technology gradually replace traditional surveying and mapping in field operations. This paper combines traditional surveying and mapping and modern information technology to develop the mobile terminal information acquisition system based on iServer. First, learn about the development of information collection technology in mobile GIS at home and abroad by consulting a large number of relevant literature, and define the value and significance of developing mobile terminal information collection system. Then, analyze the shortcomings of traditional surveying and mapping in field survey and the problems existing in mobile GIS collection information at present, combine available resource tools to form a project demand analysis, and conceive a project outline design according to the demand analysis, Finally, the information collection system based on iServer and Android is designed in detail, including software functional framework, database design and server side functional design. Theoretical analysis and practical results show that the system can effectively improve the accuracy and speed of data acquisition while reducing the cost of data acquisition.
