Abin da idan muna so mu gani a Google Maps, a tsara na Colombia a Magna-SIRGAS, WGS72 ko PSAD69?
A daidaita a ETRF89 Spain, Madrid 1870 95 ko REGCAN?
Ta yaya game da tsara na Mexico a GRS 1980 ko 1924 International?
Kwanakin baya akwai tsarin da zai baku damar yin hakan, kuma PlexScape WebServices ne. Daga abokai Girkanci halitta na Plex.Earth, wanda ke haɗa bayanai tsakanin Google Earth da AutoCAD, wanda a hanyar yanzu suna yin kyauta mai yawa ga AutoCAD 2013 wanda ya canza dokokin da aka yi.

A wannan yanayin, mun zabi UTM Zone 18 N kuma a hakika, mun ga cewa akwai batunmu.
3. Matsar da tsarin daga gefen hagu zuwa dama
Ya zuwa yanzu, abin da muka gani shine yadda ake nuna haɗin UTM a cikin Google Maps. Amma muna da sha'awar ganin wannan daidaituwa a cikin wani tsarin daidaitawa, don batun MAGNA-SIRGAS. Na farko, muna amfani da koren kibiya don nuna cewa ana daidaita daidaito ɗaya daga gefen hagu zuwa gefen dama. Ana yin wannan tare da dannawa kuma abin da zai bamu sha'awa shine duka ɓangarorin iri ɗaya ne.

4. Sanin haɗin WGS84 a cikin SIRGAS
Don wannan muna canzawa daga WGS84 zuwa SIRGAS a cikin madaidaicin panel. Sa'an nan kuma mu shawa kan icon kuma mu ce "Samun daidaituwa daga alama"Don haka muna samun daidaituwar batun da muke da shi amma a cikin sauran tsarin. Lura cewa a cikin lat/lon haɗin kai daidai yake, saboda SIRGAS ya dogara ne akan WGS84.
Amma idan muka kalli abin da ke faruwa a cikin sassan UTM, haɗin X ya bambanta santimita 3 kuma Y yana daidaita wani santimita. Kuma wannan shine dalilin da yasa za'a iya cewa duka tsarin daidai suke. Yayin da muke motsawa, wannan bambancin yana canzawa a milimita. Na bayyana cewa wannan ya kasance bisa ga sifofin da PlexScape Web Services ya tsara, duk wani abu mai ban mamaki dole ne a ba da rahoto saboda ya faru da ni sau biyu a baya.
5. Sanin haɗin kai a cikin PSAD
Za mu iya zaɓar kowane tsarin, kuma mu nemi ya dawo da haɗin gwiwa tare da "Samun daidaituwa daga alama“. Bai kamata mai nuni ya motsa ba, tunda muna a lokaci ɗaya, abin da yake dawo mana shine haɗin kai a cikin wani tsarin.

Ka yi tunanin, to, abin da muke so mu gani shine daidaitawa ɗaya a cikin tsarin biyu (ba ma'ana ɗaya ba), don haka muna kwafi haɗin kai daga hagu zuwa gefen dama sannan "Alama don kula a watan Satumba” kuma a can muna da shi. Daidaitawar guda ɗaya a ƙasa, a cikin bangarorin biyu, amma alamar shuɗi ya faɗo gare mu da gudun hijira mita 228 zuwa yamma da mita 370 zuwa kudu.
Kayan aikin Yanar gizo na PlexScape yana da ban sha'awa. A kashin kaina. Zamuyi magana wata rana game da wani aikinsa, wanda ana biyan wasu daga cikinsu, gami da wannan sauyawar daga fayil mai maki mai yawa.
