| 摘 要： | 本文通过GPS与罗盘仪面积测量的对比试验,结果表明,GPS与罗盘仪测量其精度和误差率存在明显差异,GPS的精度明显高于罗盘仪,误差率明显小于罗盘仪;GPS与罗盘仪面积测量,其模拟成本,GPS是罗盘仪的1/10,工效是罗盘仪的10倍。采用GPS测量省时、省工、省费用,在林农业上具有推广应用价值,前景广阔。

| Abstract: | Through the comparison experiment on area measure,the result indicated that there was distinct differences on pecision and erroneous proportion between GPS and compass.The precision of GPS was clearly higher than compass,while the erroneous proportion was lower than GPS.And simulation cost of GPS was 1/10 of compass,while the work efficiency was 10 times than compass.Using GPS to survey is time-saving,the labor saving and the expense saving,and has the promotion application value in the forest agriculture a... |
