Ngokuqinisekileyo ngamanye amaxesha ukhe weva malunga nesidingo sokuba neenqobo zokugweba a umvavanyi yinyaniso? Kwaye nangona ingakhange ivakala ingaqhelekanga kuwe, usenokuba ukhe wazibuza ukuba yintoni kanye kanye umsebenzi wayo ... kulungile, siza kuchaza kancinci malunga noku kukhethekileyo kobungcali, ukuba ungayifunda njani eSpain kwaye okanye ezo ezinye isayensi inxulumana ngqo ne.
Ixesha ubume bomhlaba Inemvelaphi yesiGrike, ibuye namagama amabini: "topo" (indawo) kunye "neegrafu" (ukuzoba / ukumelwa). Oku kungasinika uluvo ngokubanzi lweyona njongo iphambili yalo msebenzi, obhekisa kwinto yokwenza imiboniso yendawo, kule meko yomhlaba. Yatsho iinkcazo-ntetho zenziwa ngokusekwa kwimisebenzi eyahlukeneyo yokubala Ezinika iziphumo ezichanekileyo. Umsebenzi wokulinganisa, ukubala kunye nokumelwa kwezi kwimephu okanye kumzobo womhlaba yinto eyaziwa ngokuba yiyo uphando lwezobugcisa.
Ngoxa i ubume bomhlaba Unokugubungela amacwecwe amancinci okanye ulwandiso lomhlaba, ngokubonisa okuthe tyaba, Geodesy (enye inzululwazi ebandakanyiweyo kubume bendawo) igubungela isikali esikhulu sommeli kwaye ubukhulu becala. Inkqubo ye- umvavanyi isebenzisa izixhobo ezahlukeneyo ukulinganisa uququzelelo kunye nobukhulu bomhlaba (ikhampasi, i-theodolite, i-odometer, ...) kunye nesoftware ethile echanekileyo yokulungiselela isicwangciso semephu okanye imephu.
Umsebenzi wabo ubalulekile kwi isakhiwo, kuba inokulungiselela izifundo ezinokuthenjwa kwaye ichonge ngokuchanekileyo iinkcukacha zendawo leyo, ezinje ngokungalingani, umzekelo, eziphawula ukufaneleka kokwenza imisebenzi. Umsebenzi wayo usekwe kwi izibalo zemathematika (ulwakhiwo, ubuninzi, iipoligoni ...), ke isebenzisa amasebe ahlukeneyo kule sayensi njenge algebra okanye trigonometry. Ubuchule obusetyenzisiweyo ukulinganisa ii-coordinates bujikelezwe koko kwaziwa ngokuba yi-photogrammetry.
E-Spain kukho ifayile ye- Ubunjineli bobuchwephesha kubume bendawo, ubude beminyaka emi-3, kunye nokubanakho ukugqiba umjikelo wesibini, kwi Geodesy, iminyaka emibini, ukuze ufumane i Isidanga esiphakamileyo kwezobunjineli. Indawo ye umsebenzi wobungcali Kucatshangelwa ngaphakathi kubacebisi, kwizinto zikawonke-wonke kunye neenkampani zabucala zolwakhiwo, icandelo lezemigodi-ezolimo okanye icandelo lezamahlathi, icandelo lombane, njl.
