At present, data processing and map compilation, which constitute the key techniques in farmland grading projects, are basically completed by professional software. In this paper, the authors studied the means for performing the main work in farmland grading project under the ArcInfo 8 system. By virtue of the function of ArcInfo 8 in analyzing spatial data and attribute data, especially the VBA developing environment integrated in its ArcMap module, some important tasks can be well accomplished. They include division of grading-cells, computation of the influencing result value of grading factors or sub-factors, compilation of the influencing result map of grading factors or sub-factors, and calculation of the grading indices. The case of farmland grading in Jiangdu city is adopted to support the viewpoint of this paper.
