An accurate estimation of canopy cover can provide an important basis for forest ecological management by understanding the status and change patterns. The aim this paper is to investigate four methods random (RF), support vector regression (SVR), k-nearest neighbor (KNN), with fast iterative features selection (KNN-FIFS) modeling cover, evaluate three mainstream optical data sources—Landsat8 O...

The Pearl River Delta in South China is subject to severe eutrophication, which significantly exacerbated by the total nitrogen (TN). Remote sensing technology with large-scale synchronous observations can effectively monitor organic pollution. Statistical methods based on remote images have been widely used water quality parameter retrieval for inland rivers, reservoirs, and lakes, but seldom ...
