Landsat8分辨率非常低，只能做大尺度的分析，但是它有很多优点别的卫星没有的，首先也是最大的优点，免费；第二，在轨时间长，容易收集到长时间序列的影像，适合做大时间跨度的分析；第三，波段多，容易组合分析特定地物。 基于以上的优缺点，非常适合学校做研究，写论文。 但是在国内的实际生产中，一般很少会用到。 生产中要做到精确解译地物，一般要用到2米以上分辨率的影像。 发布于 2022-04-03 01:50 赞同 2 添加评论 分享 收藏 喜欢 收起 RS123 中国林业科学研究院 森林生态学硕士 关注 分辨率高，波段较多，数据质量好，免费，产品多。 发布于 2022-05-07 21:31 赞同 添加评论 分享 收藏 喜欢 收起 匿名用户 首先它免费， 其次它时间序列长，.
