This paper gives a review on the development of GIS and an analysis on the characteristics of currently popular GIS platform, analysis of the system development pattern and the implement technology, also, determines controls and algorithms for quadratic development. Main content introduced in this paper includes: After analyzing the special demand of Pipeline Information System (PIS), based on the parative conclusions among three different development modes of GIS, and two popular GIS platforms, with the characteristic of the COMGIS taken into account, a prehensive solution based on MapObjects to construct the PIS is proposed. Based on the characteristic of the pipeline data, a plan on the encoding and a data anization model are proposed. Especially, the concept of the geometrical work and the relative work topology analysis are discussed. The accident analysis model, the algorithm to find the shortest path, the buffering analysis, the flow to implement the transect analysis are also introduced. The ‘Dijkstra algorithm’ is implemented on basis of DepthFirst Traversal. The analysis is given on the design of the information encoding and the spatial database. The main method used within the spatial analysis of PIS is introduced. The prehensive solution of the constructed PIS is introduced in detail. The implemented functions include data input, data query, spatial analysis, map output, system maintain and so on. To a certain extent, the constructed PIS makes progress in ‘Data Integration’ and ‘System Interoperation’. The PIS is constructed with the C/S framework on basis of MapObjects, and produced solutions to several key questions in system realization.
