天津市1km土地覆被林地类型数据（2015年）

天津市1km土地覆被林地类型数据(2015年)为2015年天津市林地的空间分布。该数据是在2015年Landsat8OLI多光谱数据基础上，结合高时间分辨率的高分一号WFV宽视角多光谱相机、中国植被区划图、中华人民共和国1:100万植被图集、中国2005年土地覆被类型图等辅助数据、在线解译辅助判读系统辅助工具，在Ecognition和ArcGIS等环境下，通过专家分析和遥感自动分类结合野外考察、人工目视解译方法，按照内容和区域，采用专题制图的方式完成的。

The 1km-resolution land cover forest type dataset of Tianjin (2015) illustrates the spatial distribution of forest lands across Tianjin in 2015. This dataset was developed based on 2015 Landsat 8 OLI multispectral data, supplemented by auxiliary data including high-temporal-resolution GF-1 WFV wide-angle multispectral camera data, the Vegetation Regionalization Map of China, the 1:1,000,000 Vegetation Atlas of the People's Republic of China, the 2005 China Land Cover Type Map, and online interpretation-aided judgment system tools. The production was conducted in environments such as Ecognition and ArcGIS, integrating expert analysis, remote sensing automatic classification, field investigations, and manual visual interpretation methods, and was finalized through thematic mapping based on content and regional divisions.
