| 摘 要： | 老挝是一个发展中国家,境内的大多数地方没有开展过土地利用/土地覆盖调查。本文选择老挝琅勃拉邦省的Phonxay区为研究区域,利用Landsat OLI数据进行土地利用/土地覆盖遥感调查与分析。研究过程中,利用ArcGIS Desktop选择训练样本和验证样本,通过Python和ArcPy编程开发了图像分类、精度评价以及面积统计的工作流程序,实现了快速得到分类结果和精度评价信息,分类结果的总精度为89.53%,Kappa系数为0.81。

| Abstract: | Lao PDR is a developing country where people rarely processed land use/land cover detection in most areas. In this study we select the Phonxay District, Luang Prabang Province as the study area, using Landsat 8 Operational Land Imager ( OLI) data to ac-complish land use/land cover detection and analysis. First, we select the training samples and test samples artificially from OLI ima-ges by ArcGIS Desktop. Then we programme in Python (&ArcPy) to create a workflow including image classification, precision evalu-ation and area statistics, which we can achieve the classification results and the accuracy evaluation directly from. Finally after pro-cessing, the total accuracy result of the classification is 89. 53％ and the Kappa Coefficient is 0. 81. |
