Two forms of spatial interpolation, the interpolation of point and areal data, are distinguished. Traditionally, point interpolation is applied to isarithmic, that is, contour mapping and areal interpolation to isopleth mapping. Recently, areal interpolation techniques have been used to obtain data for a set of administrative or political districts from another set of districts whose boundaries...

Precipitation data provide a crucial input for examining hydrological issues, including watershed management and mitigation of the effects floods, drought, landslides. However, they are collected frequently from scarce often insufficient network ground-based rain-gauge stations to generate continuous precipitation maps. Recently, maps derived satellite have not been sufficiently linked rain gau...

Bathymetry is one of the most conspicuous variables to consider in any study involving marine environments. In developing countries, accurate and up to date bathymetric charts are rare or in most cases limited to local areas, most of them available only in hardcopy format. This is the case of the Yucatan submerged platform. In this study, we compare and discuss the performance of two spatial in...

This study focuses on evaluating the suitability of three interpolation methods in terms of their accuracy, for small urban catchments. The Bridgewater Creek catchment in south Brisbane is the region of study. Thirteen storm events measured over 24-hours are interpolated using an inverse-distance weighted average method, thin plate smoothing spline, and an ordinary kriging technique. The delete...

Various studies are currently underway on PM (Particulate Matter) monitoring in view of the importance air quality public health management. Spatial interpolation has been used to estimate concentrations due that it can overcome shortcomings station-based and provide spatially continuous information. However, is affected by a combination several factors, only considers spatial relationship betw...

This paper analyzes the validity of temperature maps obtained by means of single and mixed interpolation methods. In this context, several interpolation methods are used for the temperature mapping: inverse distance square (IDS), ordinary kriging (OK) and co-kriging (CK) and mixed methods (combined global, local and geostatistical methods). And the validity of the maps is checked through the cr...
