Abstract: Aiming at the functional limitations of the ArcObjects component, this paper proposes a development method with custom-made component to extend its application functions, displays the design and implementation method of GIS application software based on ArcObjects component and gives the detail demonstration of custom-made component design and realization through application programming examples. The widely use of the developed component in the GIS applications shows that the development method with custom-made component further enhances the reuse quality of code, accelerates the development speed of the application software.
