The spatial data model, data structure, spatial analysis is a key issue of 3DGIS. Three-dimensional data analysis and making are the driving of 3DGIS, the establishment and visualization of three-dimensional city model (3DCM) is an important task and a basic content.This paper discussed some basic problems such as spatial data model, data acquisition, modeling, texture mapping in 3DGIS.Through analysis example, its results showed that there are many problems in 3DCM, For example, the quick acquirement of spatial data and many people are engaged in. We should do more research in the future.Based on the needs of "digital Harbin", The paper discussed the organization of three-dimensional city model. On this basis, the paper set a overall idea of the reconstruction in the area of three-dimensional city model. Finally, according to the principles of system development, in order to expand the "digital Harbin", the paper discussed Harbin 3DGIS. To make the system run more smoothly, the paper put forward some points about the visual optimization strategy. The establishment of Harbin 3DGIS based on C #. Net &ArcGIS Engine& CityMaker web SDK, the control, view, location of the scene, property query become a simple function to achieve.
