Chiwonetsero chosachokera ku zithunzi
Zaka zingapo zapitazo, pa msonkhano wapachaka wa “Kudula ndi Mapu” wochokera ku United States ndimakumbukira kuti ndinaonapo mmodzi wa anthu amene amasuta amene amakusiyani osalankhula, osati chifukwa chakuti Chingelezi chathu chamaphunziro sichimafanana ndi gringo caliche. Chinali chiwonetsero cha Kevin Sahr, Jon Kimerling ndi Denis White pachiwonetsero chawo "Geodesic Discrete Global Grid Systems", chomwe m'chinenero chathu cha Chilatini chimatanthauza:
Chiwonetsero chosachokera ku zithunzi.
Ntchito yayikulu ya omanga a geodesy inali yosinthira mawonekedwe amtundu wa hemispherical kukhala chinthu chomaliza cha mawonekedwe amakona anayi, pafupifupi mawonedwe onse a geodeic amaganiziridwa mu mfundo yoyambirira yomwe adalengedwera, ndipo ndi "kusindikiza mamapu", omwe ndi chifukwa chomwe pafupifupi pafupifupi ma ellipsoid onsewa, komweko amakhala pafupifupi rectangle ndipo chifukwa chake chachikulu zaka khumi ndi zisanu zapitazo chinali chokhoza kusindikiza mamapu awiri pamlingo wofanana ndikutha kuwaphatikiza m'mphepete mwawo.
Mwa maganizodwe a njonda izi zachokera mfundo yakuti pa nthawi imeneyi a sayansi, kusindikiza si chifukwa chokha tinachoka quasi-ozungulira Masamu dziko lapansi, koma cholinga cha geolocation; bola zowonera zida GIS / CAD ndi ntchito mafoni ndi kusinthasintha ntchito luso, pali zochepa kufunika kuwerengetsera zovuta geolocation. kusanthula Izi zimapangitsa kudzipereka kuganizira osachepera unit wa chizindikiritso geodesic mu kansalu m'mbali yokhota kumapeto, yomwe akuyenera kulandira makona ndi kupindika dziko lapansi, kotero izo zangokhala chinthu china chimene mbali ya pamwamba, takambiranazi m'mphepete kupindika kwa dziko lapansi ndi amene pakati limafanana ndi malo mapangidwe a dziko lapansi, kapena kumalo ozizira mzere spheroid.
Utsi wabwino umene umatsutsana ndi umene unatipangitsa kuti timvetsetse Mercator m'kalasi la Geodesy.
