Over one hundred years ago New York City residence experienced the negative impact of industrial and economic growth. Approximately 600 million gallons a day of raw sewage conveyed by pipes was dumped in the Harbor. The untreated wastewater contained an array of contaminants. To address the public health issue the city collected data that define the scope of the harbor's degradation. Data collected for more than 100 years were migrated into Geodatabase and used to analyze the condition of the harbor over time. Due to complex geomorphology, hydrodynamics and biogeochemistry of the Harbor traditional modeling technique doesn't analyze the true condition of the Harbor. An interpolation technique that is flexible and allows multiple variables to be processed on the same model is developed to support the Harbor study. This paper describes the developing process of developing the master interpolator technique.
