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%。
In this paper,by means of comparing the areas measured by pocket GPS of 25 land blocks in Changchun with the same land listed on 1∶500 topographic map,we get the result that when the measured area is larger than 100 000 m2,the one time precision of pocket GPS area measurement is 0.32%~0.56%,the average precision is 0.51%;by using the regression analysis technology to correct the measured area by pocket GPS,the average precision of measured area can be enhanced to 0.3%.
