An Improved Coastal Marine Gravity Field Based on the Mean Sea Surface Height Constraint Factor Method

Remote Sensing, 2022
Construction of a high spatial resolution and high precision marine gravity field in coastal areas is constrained by the low quality and sparse coverage of altimetry data, except for limited shipborne and airborne gravity surveys. To address this problem,

Spatial Prediction of Real Sulfur Data Using the Ordinary Kriging Technique and Lognormal Kriging [PDF]

المجلة العراقية للعلوم الاحصائية, 2022
This research deals with the spatial prediction process in order to obtain the optimal prediction when the data are distributed normally. In this paper, we used the ordinary kriging technique and the lognormal kriging after taking the logarithm of the ...

Review of the Kriging Technique Applications to Groundwater Quality

Journal of Engineering, 2021
Kriging, a geostatistical technique, has been used for many years to evaluate groundwater quality. The best estimation data for unsampled points were determined by using this method depending on measured variables for an area.

Synthetic TEC Mapping with Ordinary and Universal Kriging [PDF]

2007 3rd International Conference on Recent Advances in Space Technologies, 2007
Spatiotemporal variations in the ionosphere affects the HF and satellite communications and navigation systems. Total Electron Content (TEC) is an important parameter since it can be used to analyze the spatial and temporal variability of the ionosphere.

PERBANDINGAN INTERPOLASI SPASIAL DENGAN METODE ORDINARY DAN ROBUST KRIGING PADA DATA SPASIAL BERPENCILAN (Studi Kasus: Curah Hujan di Kabupaten Karangasem)

E-Jurnal Matematika, 2012
Kriging as optimal spatial interpolation can produce less precise predictive value if there are outliers among the data. Outliers defined as extreme observation value of the other observation values that may be caused by faulty record keeping, improper ...

Pendugaan Metode Ordinary Kriging

Jurnal Penelitian Ilmu Sosial dan Eksakta, 2022
Geostatistika merupakan ilmu yang berfokus pada data spasial. Dalam geostatistika terdapat metode pendugaan untuk menangani variabel yang mempunyai nilai bervariasi dengan berubahnya lokasi atau tempat yang disebut variabel teregionalisasi. Metode pendugaan yang digunakan untuk menangani variabel teregionalisasi disebut metode kriging.

PERBANDINGAN PENDUGAAN METODE ORDINARY KRIGING DAN METODE ORDINARY KRIGING DENGAN TEKNIK JACKKNIFE

MAp (Mathematics and Applications) Journal, 2023
Pada analisis spasial jika terdapat data yang memiliki distribusi tidak normal, maka akan menghasilkan prediksi yang kurang baik. Untuk mengatasi hal tersebut digunakan metode ordinary kriging dengan teknik jackknife. Dalam metode ordinary kriging dan ordinary kriging dengan teknik jackknife perlu memperhitungkan semivariogram.
