| 摘 要： | 利用手持GPS对不同大小的林地面积进行了测量,并分析了其误差规律,给出了单次测量误差的纠正方法.结果表明:林地形状对测量结果无显著差异;对于面积大于1h㎡的林地,可以直接用手持GPS单次测量结果作为林地的面积值;面积在0.3～1.O h㎡的林地,可以将手持GPS单次测量结果代入误差模型中,以计算出的理论值作为林地的面积...

| Abstract: | The error rule of measuring forestlands of different sizes by handheld GPS was systematically analyzed,and a correction method for single measurement error was given.Results showed that the measurement results of forestlands of different sizes had no significant difference.For the forestland area more than 1.0hm2,the single measurement value by the handheld GPS can be directly used as forestland area.For the forestland area between 0.3 and 1.0hm2,the theoretical value calculated by putting the GPS single me... |
