Géostatistik make teori proses stokastik jeung kasimpulan statistik keur nalungtik fenomena geografi. Géostatistik geus ilahar digunakeun dina widang geo-sciences. Metoda Géostatistik oge dipake di geologi minyak, hidrogeologi, meteorologi, oseanografi, geokimia, kahutanan, kontrol lingkungan, ekologi lanskap, pertanian (hususna keur kacocogan tatanen) jeung sajabana.

Konsep dasar géostatistik nyaeta yen skala mangrupakeun variasi spasial. Data spasial "terikat" nunjukeun yen variabiliti hampir sarua "tanpa" ningali lokasi titik data. Sanajan kitu, data spatial dina sababaraha kasus lain ngarupakeun data "terikat". Nilai data nu mana raket sacara spatial ngabogaan "variabiliti" anu saeutik dibandingkeun jeung nilai numana leuwih jauh antara hiji kanu sejenna. Sifat pola ieu beda-beda tina hiji susunan data ka susunan data nu sejenna; 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
