Agricultural statistics on small farms are critical for informing sustainable development policies, but often suffer from selection bias and are time consuming and costly to collect. Less burdensome and reliable methods are needed. We report on a scalable method using a respondent's knowledge about their land, high resolution imagery, and tablet devices to draw spatially explicit plot boundaries. We find the method may work best with respondents that own their plots are farmers, and for smaller plots (

一种使用平板电脑和高分辨率图像绘制小型农业地块的受访者驱动方法

小农场的农业统计数据对于为可持续发展政策提供信息至关重要，但往往受到选择偏差的影响，收集起来既费时又费钱。需要较少负担和可靠的方法。我们报告了一种可扩展的方法，使用受访者对其土地、高分辨率图像和平板设备的了解来绘制空间明确的地块边界。我们发现该方法可能最适用于拥有土地的受访者是农民，而对于较小的土地（
