Kiʻi kiʻi GoogleEarth kiʻi

He i mua kamailio e pili ana i e hoʻouka i kahi moʻokūʻauhau i Google Earth inā mākou iʻike i kona heluna.

No laila, e ho'āʻo ma hope, inā loaʻa iā mākou heʻike ma GoogleEarth, pehea e kiʻi ai a hoʻololi i kēia.

ʻO ka mea mua, uaʻike mākou i ka mea maikaʻi a no ke ahaʻaʻole e Google Earth, ma mua ua kamaʻilio mua mākou. ʻĀ, ʻo ka mea mua e hōʻike ʻia ka ʻike, a ʻo ka mea a mākou e makemake ai e hoʻoiho i kēlā kiʻi a georeferensi iā ia. Pono mākou e hoʻopau i ke koho ākea no ka mea ʻaʻole e deforma ka hōʻike ʻekolu dimens i kā mākou ʻike, pono nō hoʻi mākou e ʻike aia ka panana ma ke kūkulu ʻākau a me ka ʻike kū.

1. Mākaʻu i ka wahi o ka hoihoi

Pono ʻoe e hana i kahi pahu me ka mea hana ʻo Google Earth polygon, ma nā kihi ʻehā o ke ākea āu e makemake ai e ʻoki. A laila kokoke loa ʻoe e kiʻi i nā kikowaena UTM, kau i ka kuhikuhi ma luna o ke kihi, pono ʻoe e hoʻomanaʻo ʻo ke kikoʻī o GoogleEarth ma kahi o kanakolu mau mika no laila mai hoʻopilikia i nā decimals.

I kēia manawa, e hele ana mākou eʻoki i ka pahu, pono mākou e neʻe aku iʻole e waiho i nā kikokikona a me ka panana i loko o ka pahu a hana mākou i ka paʻi puke me ka keyboard a kope mākou i ka pena.

Ma kēia pae hiki ke ʻokiʻoki i ka pena, ʻoiai ke hana ʻana me ka pololei hou aʻe he mea hoʻonele manawa ia ma waena a i ʻole ma waho a i waho paha ka laina ʻulaʻula. Koi aku au, ʻaʻole kūpono ka hale paʻahao ʻo GoogleEarth e hakakā ai no kekahi mau mika. I kēia manawa wehe mākou iā ia me ka Office Picture Manager (hele mai ia me Windws) e ʻokiʻoki i nā lihi me ka maikaʻi loa me ka koho hua a huki i nā wēlau, hana wau ma aneʻi no ka mea makemake wau e hoʻomaikaʻi iki i ka ʻokoʻa i ke kiʻi.

ʻO kēia ke kumu hopena i ka hoʻohālikelike a me ka hoʻololiʻana.

2 Ka laweʻana i ka pahu i Microstation

I kēia manawa e hele aku mākou i kahi georeferity me ka hoʻohana ʻana iā Microstation V8, kope mākou i ka ʻikepili hoʻohui i ka excel i ke kauoha x, y, z a mālama iā ia i ka format .txt no ka hoʻohana z ʻole. ʻAʻole kēia e komo i nā kiko i ka wāwae me nā kī.

I kēia manawa i ka Microstation, inā ʻaʻole i hoʻoheheʻe ʻia ka palake hoʻoiho ʻikepili xyz, hoʻoulu mākou iā ia me nā pono hana / pahu hana a koho iā ia ma ka hopena. Me kēia mea hana lawe mākou i nā helu mai ka faila excel a me voila, ua loaʻa iā mākou ma ke kumu o ka hoʻonui i ke kiʻi.

No ka hoʻomaopopoʻana i nā helu iʻikeʻia e hiki iāʻoe ke hoʻololi i kaʻeleʻele a me ka lahilahi o ka helu.

3 ʻO Georeferencing ke kiʻi ma Microstation

ʻO nā mea a pau i koe e hoʻokomo i ke kiʻi, no kēia mea mākou e hoʻohana ai i ke kauoha raster manager, me ke koho "place interactive" a waiho i loko o nā helu ʻehā.

No ka hoʻolālāʻana, hoʻohana mākou i ke kauoha o ke kaula, i ke koho o nā heluʻehā a hōʻike mākou i kēlā kihi kēia kihi o ke kiʻi e kahaki ana i nā mea i kūlike.

Ke kuhikuhi mākou i nā helu ʻehā a laila kaomi pono mākou i ka pale a ʻo ia wale nō. ʻO ke kiʻi googleearth georeferencing. I kēia manawa mai ʻaneʻi hiki iā ʻoe ke mālama i kēia kiʻi me kekahi ʻano georeferencing.

4. Hoʻopiʻi i ka pono o kēia

Ke koi nei au e like me ka'ōlelo aʻo hope loa, ua lōʻihi wau i ka hoʻomaopopoʻana i ka manawa o kēia huakaʻi i hala iaʻu. Mai hoʻohana i kēia no ka hana koʻikoʻi, no ka mea,ʻaʻole ia e lawelawe i nāʻikepili GoogleEarth. I mea e hōʻike aku ai iā ʻoe i kahi laʻana, superimpose wau i ka palapala ʻāina cadastre ma luna.

Hoʻohou, no ka kiʻiʻana i nā kiʻi ma kahi alaʻehaʻole e hiki ke hanaʻia ma o ka hoʻohui pololeiʻana mai 'ōnaehana nui aiʻole me Palapala kiʻi kiʻi kiʻi kiʻi Google
