Many uninhabited islands are far away from the mainland and a lot of management difficulties are caused by above
factors. In order to know the situation of the uninhabited islands clearly and timely, it's necessary to use the remote
sensing to recognize the uninhabited islands. This paper discusses the remote sensing recognition methods of the relevant
characteristics of uninhabited islands based on a wide range of remote sensing data fusion and integration. The first
method is using the combination of TM band data to recognize uninhabited islands. The second method is using the spot
image data to compare with the spatial island layer to recognize uninhabited islands. The results show that they are
effective methods for us to recognize the uninhabited islands and the time could be saved. By contrast, the first method is
a useful complement to location the uninhabited islands but is difficult to get the accurate area. The second method is
important means to get the relatively accurate area of the uninhabited islands. The high resolution imagery is very useful
to recognize the small uninhabited islands and the relatively accurate area could be calculated by overlapped the spatial
island layers.

In order to manage the internal resources of Gulf of Tonkin and integrate multiple-source spatial data, the establishment
of region unified plan management system is needed. The data fusion and the integrated research should be carried on
because there are some difficulties in the course of the system's establishment. For example, kinds of planning and the
project data format are different, and data criterion is not unified. Besides, the time state property is strong, and spatial
reference is inconsistent, etc. In this article the ARCGIS ENGINE is introduced as the developing platform, key
technologies are researched, such as multiple-source data transformation and fusion, remote sensing data and DEM
fusion and integrated, plan and project data integration, and so on. Practice shows that the system improves the working
efficiency of Guangxi Gulf of Tonkin Economic Zone Management Committee significantly and promotes planning
construction work of the economic zone remarkably.
