FUI Water Color of inland waters in China at 30-m in 2015

The first 30-meters FUI water color product of China. The product was developed using time-series Landsat 8 imagery and FUI water color retrieval method. Taking into account the huge amount of computational and storage space required for the national-scale water color mapping, the high-performance Google Earth Engine (GEE) cloud-based platform was introduced to support the computation. First, a cloud-free composite in China for the summer of 2015 was generated using time-series Landsat-8 imagery and the Best-Available-Pixel (BAP) compositing algorithm. Then, the first 30-merters FUI water color product of China was developed using the generated BAP composite and the Google Earth Engine computing platform. The first 30-meters FUI water color product can promote the understanding of the water color of water bodies in China, and provide very important information for preserving and restoring inland water quality. The details of the product is described in "FUI_WaterColor_2015China_Readme.docx"中国首款30米分辨率FUI水体色度产品。该产品基于时序Landsat 8遥感影像与FUI水体色度反演算法研发而成。考虑到全国尺度水体色度制图所需的海量计算与存储空间，项目引入高性能谷歌地球引擎（Google Earth Engine，GEE）云平台支撑相关计算工作。首先，借助时序Landsat-8遥感影像与最优可用像素（Best-Available-Pixel，BAP）合成算法，生成2015年夏季全国范围无云合成影像。随后，基于生成的BAP合成影像与谷歌地球引擎计算平台，完成中国首款30米分辨率FUI水体色度产品的研发。该产品有助于增进对中国内陆水体色度特征的认知，可为内陆水体水质保护与修复提供关键支撑信息。该产品的详细说明请参见"FUI_WaterColor_2015China_Readme.docx"文档。
