Like georeferenced orthophotos ma Google Earth

He i mua kamailio e pili ana i like georeferenced palapala ma Google Earth, eʻike kākou i keʻano o kā mākou hana like me kahi'ōlohelohe. E hoʻomaopopoʻia e kahi'ōlohelohe, kahi kiʻi kūlohelohe, a uaʻike mākou i kona pili.

Google Honua noi'āpana eha o ka 'ike, a hoʻopili like i na ioauoa o kēlā me kēiaʻaoʻao o ka orthophoto (nānā i ke kiʻi ma lalo nei), he nui manaoio i ka'ōnaehana i ka palena pau o ka hewa, mai na orthophotos o ka mosaic mea,ʻaʻole i ka maka aha kona lua penei coincide me oiaio akau, aka, ka mea, he poe Hoʻohana o meridians a me laua.
Eia naʻe i kuhihewa no ia, no ka mea, Google Earth noi mai ka mea mau palena eha orthophoto waihona lakikū a me longitudes, no laila, i kēia, e pono e kiʻi eha.

I kēia hihia, e manaʻo mākou e hana mākou i Microstation.
E laila, pani ma ka anu u:

Ike i ke kiʻiʻikepili

1. Orthophoto make i loko o Microstation, no ka mea e wehe i ka waihona, e koho i raster manakia / paʻa, e hoʻopio i ke koho, aʻae pä wahi.

2. Inā ʻaʻole ʻoe e ʻike i ke kiʻi, e koho iā ia mai ka luna raster me ka pihi ʻiole ʻākau a hoʻāla i ke koho "fit raster to view"

3. I kēia manawa, e ʻike i nā hoʻonohonoho, hoʻāla i nā mea hana / pahu pahu / xyztext mea hana a hoʻohana i ke kauoha "label coordinates"

2. Pono ʻoe i nā hoʻonohonoho o nā kiko waena o nā palena orthophoto, no laila ʻo ke ala maikaʻi loa e hana i nā laina a puni, e koho i kēia manawa i ke kauoha "label coordinates" a kaomi ma nā kiko waena o nā laina.

4. Me ka mea mua i na wahi m palena iki m i kā mākou, palena iki, a me kā mākou.

5. Ma ke ala, e hoʻokuʻu aku i ke kiʻi i nā formats i kākoʻo ʻia e Google Earth, i koʻu hihia aia ma .ecw, no kēia wale nō i ka mana raster e koho ʻoe i ke kiʻi me ka pihi ʻiole ʻākau a koho i ka "save as", i kēia. e hoʻokuʻu aku au i ka format .tif

UTM kahi kūlike hoʻololi 'Geographic

ʻOiai oe ke loaa ia 'ana me ka' ē aʻe Mau koho Paʻamau o ka microstation, e kahaki mākou i kēia kaʻina i nā manawa a pau.

6. Kaʻu wahi mea i loko o Honduras, koʻu wahi e like penei: X = 489885.60, 1579986.30 Y = X = 493260.30, 1577678.70 Y =

E like me kaʻu e makemake ai e hoʻololi iā lākou i nāʻano kuhikau a me nā manawa lōʻihi, e hoʻohana wau i kēia pūnaewele mai ko mākou hoaaloha 'O Gabriel Ortiz Ua i papa i kouʻaoʻao. Ma keia paena au koho i ka spheroid, i loko o koʻu hihia o 1866 Clarke, laila, i ka wahi, i mea ka 16, i ka'ākau hemisphere (N) a me ka uku i kahi kūlike o.

Ma muli o ka noiʻana mai o Google Earth iaʻu no kaʻikepili i loko o ka hoʻopalipalima, hoʻololi wau i nā kekona i ka decimal ma ka māheleʻana iā lākou i kanaono, a laila e like me nā minuke a me nā huina. Hoʻomaʻinaʻia ka hana like me nāʻekalesiaʻehā, mai pale a puni no ka mea ma kēia kikowaena hōʻano he decimal o kahi alaʻelua he mamao nui. Hiki iāʻoe ke hana i kēia me kahi papahana kūikawā, he nui ka poʻe ma waho,ʻaʻole ia ke kumuhana o ka pou.

Ka laweʻana i ka kiʻi i Google Earth

7 E wehe i ka Google Earth a huli hou a emiʻole paha i ka'āina kahi e noho ai ka'ōpopo; Manaʻo wau ua paniʻia ka Google Earth no ka mea e hoʻopauʻia ana ka nui o nā kumuwaiwai.

8. E koho i ke koho "hoʻohui kiʻi uhi", ʻimi ʻoe i ke kiʻi ma ka polokalamu kele pūnaewele a hāʻawi iā ia i inoa kūpono no kāu mau kumu

9. Ma ka hope uku pila o ka panel (wahi) Oe iloko o na wahi eha ma kekimala degere format Ka, i manao ole holoiia i ka degere hōʻailona.

10. Ano, ho'āʻo e zoom i loko i ka wahi, a ike i kaʻana o ortho; A hoailona maikai o ia i ka pahu i ka huliāmahi o ke kiʻi.

11. Ma ka papa manawa, ma luna o nā ʻaoʻao o kēia panel hiki iā ʻoe ke koho i kahi waiwai transparency, a laila ke koho "ʻae" a ʻo ia nō.

Ma ka lā aʻe, e ho'āʻo mākou i ka hoʻololi, e kiʻi i kahi kiʻi o Google Earth a hoʻokumu i ka heluna. 'Alekana maikaʻi a ke hōʻike neiʻoe iaʻu i ka hoʻounaʻana aku iāʻoe i kahi leka hoʻomaopopo maʻamau :)).
