Variogramma Telpiskā autokorelācija Matemātika Parastais krigings Telpiskie punktu modeļi Interpolācija

description

Bakalaura darbā aplūkota programmas R veiktspēja apstrādāt, analizēt un attēlot telpiska veida datus. Aprakstīti telpisko datu veidi, kā arī to struktūra programmā R. Veikts ieskatas telpiskajos punktu modeļos, kā arī telpiskajā autokorelācijā un interpolācijā. Paņemti dati no Latvijas meteroloģijas centra par relatīvo mitrumu vairākās stacijās. Izpētīta to autokorelācija ar variogrammas palīdzību. Meklēts labākais modelis empīriskajai variogrammai, kā arī veikta interpolācija pēc vairākām metodēm (Tīsena poligonu, inversā attāluma un parastā kriginga) lai iegūtu vērtības vietās, kur mērījumi netika veikti. Tika secināts, ka programma R ir ļoti kompetenta darbībai ar telpiskajiem datiem, relatīvā mitruma dati ir korelēti telpā, un inversā attāluma, parastā kriginga interpolācijas dod līdzīgus rezultātus šādiem datiem.
