| 摘 要： | 通过用手持GPS对长春市城区25块街区的测量面积与1:500地形图上同名地块面积的比较,得出当地块面积大于10万m2时,手持GPS一次测量的面积精度为0.32%～0.56%,平均为0.51%;通过回归分析技术对手持GPS测量的面积进行改正,所测面积的平均精度可提高到0.3%.

| Abstract: | By means of comparing the areas measured by pocket GPS with the ones in 1∶ 500 topographic map in 25 blocks,this paper gives the following conclusions:(1)When the measured area is bigger than 100 000 m2,the one time precision of area measured by pocket GPS is 0.32%~0.56%,the average precision is 0.51%;(2)Using the regression analysis technology to correct the area measured by pocket GPS,the average precision of measured area can be enhanced to 0.3%. |
