According to the actual situation of aided design system of land consolidation, the shortcomings of the traditional aided
design software of land consolidation are concluded in the paper. And with the development of the technology of the
computer aided design and software, the aided design system of land consolidation on the platform extended
graph-element, which adopts the mature and advanced technologies of extended graph-element as well as parametric
design, and displays geospatial phenomenon to the users by the interactive design technology with CAD, is constructed
to improve the speed and quality of the design. Considering about the main problems of the current land consolidation
aided design, following the practical and systematic design idea, functional modules of the land consolidation aided
design are constructed, and the composition and the working process of each function module is described in details.
