| 摘 要： | 针对丘陵地坡度平缓、人工地貌较多、地形破碎，因而影响等高线插求点的高程精度这一问题，将大平板仪、解析点和数字化三种测绘法的丘陵地等高线插点的高程精度作了比较，结果表明解析点测绘法较适宜丘陵地等高线的测绘。

| Abstract: | The height precision of contour interpolation points must be affected because of the factors of the grade relaxation, a mass of artificial physiognomy, and topography crashing in upland area. The different methods, such plane-table, analytical and digitalization as mapping methods, are compared with each other. The conclusion is that analytical mapping method is suitable for upland contour mapping. |
