2019年全球30m分辨率森林覆盖产品

基于Landsat卫星数据研发的全球30米分辨率森林覆盖产品投影方式采用WGS84坐标系统经纬度投影（EPSG:4326）；以30米分辨率分块输出，10°×10°分块，共计504块；输出格式为GeoTIFF。采用机器学习、大数据分析等先进技术，基于长时间序列的多源卫星遥感数据，建立30米分辨率全球变化产品快速生产流程和方案，实现全球30米产品快速生产。

The global 30-meter resolution forest cover product, developed based on Landsat satellite data, adopts the WGS84 geographic coordinate system with latitude-longitude projection (EPSG:4326) as its projection method. It is output in tiled units at 30-meter resolution, with each tile covering a 10°×10° geographic extent, totaling 504 tiles; the output format is GeoTIFF. By utilizing advanced technologies such as machine learning and big data analysis, along with long-term time-series multi-source satellite remote sensing data, a rapid production workflow and solution for 30-meter resolution global forest cover products has been established, enabling the fast production of these global 30-meter forest cover products.
