Comparison of interpolation methods for estimating spatial distribution of precipitation in Ontario, Canada

Abstract: ABSTRACT:In this study, different interpolation techniques in a geographical information system (GIS) environment are analysed and compared for estimating the spatial distribution of precipitation in the province of Ontario, Canada. A high-resolution regional climate modelling system [Providing Regional Climates for Impacts Studies (PRECIS)] is used to simulate the present and future (2071-2100) precipitation events for 12 meteorological stations over Ontario. The results verify that for the present case PREC… Show more

“…Surface fitting algorithms can be classified as deterministic or statistical methods. Global polynomial surface (GPS) and local polynomial surface (LPS) functions are deterministic methods commonly used to interpolate rainfall [9]. All point measurements are considered when using the GPS method.…”

“…Some examples of RBFs include spline and multiquadric interpolation. RBFs generate a smooth surface and the degree of smoothness is dependent on the kernel parameter [9]. Conversely, IDW is an inexact interpolator.…”

“…Minimum Curvature memberikan hasil interpolasi yang lebih halus, sehingga tergolong interpolator non-eksak (Keckler, 1994;Dressler, 2009 Tinggi muka air tanah semakin turun ke arah timur, walaupun terdapat sedikit perbedaan secara minor (gambar 3). Perbedaan hasil tersebut disebabkan masing-masing teknik interpolasi memiliki cara kerja yang berbeda, baik itu secara eksak dan non-eksak (Wang dkk., 2014 (Bourgoyne dkk., 2016).…”
