资源简介:
基于澜湄流域2017年第一季度16m中分正射遥感影像,利用ArcMap软件,采用水体自动提取与人工目视解译相结合的方法进行水面矢量化,得到该区域水面矢量专题信息产品。提取水面要包括河流、湖泊、坑塘。最小线状地物图上宽度大于60米,面状地物最小图上单元为6像元×6像元。
Based on the orthorectified remote sensing imagery with 16-meter spatial resolution in the first quarter of 2017 over the Lancang-Mekong River Basin, this water surface vector thematic information product was generated through water surface vectorization using ArcMap software, which adopted a combined approach of automatic water body extraction and manual visual interpretation. The extracted water bodies include rivers, lakes and ponds. The minimum mapped width of linear water features exceeds 60 meters, and the minimum mapped unit for areal water features is 6 pixels × 6 pixels.
