INTERPOLASI SPASIAL DENGAN METODE ORDINARY KRIGING MENGGUNAKAN SEMIVARIOGRAM ISOTROPIK PADA DATA SPASIAL (Studi Kasus: Curah Hujan di Kabupaten Karangasem)
Abstract: Spatial data is data
that is presented in the geographic of an object, related to the location,
shape and relationship of the earth in space. One of example of spatial data is
rainfall. To determine the value of rainfall in an area, built to predict rain
post information regarding rainfall. Spatial interpolation is used to estimate
rainfall by collecting rainfall values held rain heading around. Assessment
methods used in the estimate the rainfall in the Karangasem district is
ordinary kriging using isotropic semivariogram that takes into account height
on spatial data. Isotropic semivariogram which only takes into account the
distance alone. Ordinary kriging method using isotropic semivariogram that
takes into account height value
estimated rainfall is much different to the values at the control points
Amlapura and Besakih. Interpolation on 3D data are not suitable for use on
ordinary kriging method, grouping should be done at the data into a few weeks
to application of ordinary kriging interpolation method using anisotropic
semivariogram on 3D data.
