Géostatistika

Géostatistik maké téori proses stokastik jeung kasimpulan statistik keur nalungtik fénoménagéografi. Géostatistik geus ilahar digunakeun dina widang géo-sciences. métodeu  Géostatistik ogé dipaké di geologi minyak, hidrogeologi, meteorologi, oseanografi, geokimia, kahutanan, kontrol lingkungan, ekologi lanskap, pertanian (hususna keur kacocogan tatanen) jeung sajabana.

Konsép dasar géostatistik nyaéta yén skala mangrupa variasi spasial. Data spasial "terikat" nunjukkeun yén variabiliti hampir sarua "tanpa" ningali lokasi titik data. Sanajan kitu, data spatial dina sababaraha kasus lain mangrupa data "terikat". Nilai data nu mana raket sacara spatial mibanda "variabiliti" anu saeutik dibandingkeun jeung nilai nu mana leuwih jauh antara hiji kanu séjénna. Sifat pola ieu béda-béda tina hiji susunan data ka susunan data nu séjénna; unggal susunan data mibanda fungsi nu "unik" sarta jarak antara dua titik data. Variabilitas ieu ilaharna diitung salaku fungsi nu disebut  semivarian.

Spatial autocorrelation bisa diitung ngagunakeun correlograms, covariance functions jeung variograms (=semivariograms).

Topik anu aya hubunganna: statistik, géologi, GIS, remote sensing, kriging
