Lake Okeechobee is a large shallow lake with over 46% (as of 2006) being underlain with phosphorus-enriched mud sediments. Hurricane-induced sediment re-suspension plays a significant role in the nutrient cycling of this lake. It is important to develop optimal geospatial models with low uncertainty to track the distribution and changes of total phosphorus (TP) and total nitrogen (TN) over time (1988-2006). In this book, geographically weighted regression (GWR), ordinary least square (OLS) regression, ordinary/co-kriging, and regression-kriging were calibrated, validated and compared using...
