Hoʻololi i kekahi palapala 'āina o NAD27 i WGS84 (NAD83) me ka AutoCAD

Ma mua o ko mākou kūkākūkāʻana i ke kumu o ko mākou kaiaulu, ka nui o nā kiʻiʻimi kahiko aia ma NAD 27, ke hoʻohanaʻia ka NAD83 e kaʻaha honua, aʻo ka mea i kapa iā iaʻo WGS84; ʻoiai ua like nā meaʻelua ma ke kumu hoʻokahi,ʻo ka Datum wale nō (koe wale nō ma ka Māka UTM).

He nui komo i loko o ka huikau weliweli e manaoio ana i ka palapala wale pono ia e hoʻoneʻe i ka maʻi lele, ma ka hihia o Honduras i cartographic lau mai nei ka mea, o 202 6 mika akau a me ka hikina mika; Maopopo keia hiki ke hoopili ia i nā hana, nae ma ka hoolilo ana i ka reprojection me ia e ia, o ka lako polokalamu mea i ka moʻo o ka geodesic ana i ka hoʻololi ellipsoid mea i kekahi palapala 'āina kahi a pau vertices i ua hoʻoneʻe i loko o ka maka aha ka waiwai ʻaʻole mau, no laila ʻaʻole ia e hoʻopili i kahi palapala ʻāina "neʻe wale".

Hiki ke hana ʻia me Microstation Geographcis, ARCGis a i ʻole Manifold; i kēia hihia e ʻike mākou pehea e hana ai me AutoCAD Map3D. E hoʻohana wau i kaʻu mea (Map3D) ma ka ʻōlelo Pelekania no laila e hoʻāʻo mākou e mālama i kekahi mau inoa ʻoiai lākou i nā menus a me nā pihi a e like me ka hoa a CADGEEK i hōʻike mua ai. Pono ʻoe e ʻike ʻo AutoCAD Land Desktop a me AutoCAD Civil 3D, ua hoʻopau ʻia ka palapala ʻāina ʻo AutoCAD i kēia noi a AutoCAD i kāhea ai iā Map3D, ʻaʻole i loli ke kaʻina hana no nā mana like ʻole.

Hoʻomaka kākou ma ka hanaʻana i kahi palapala 'āina ākea:

E hāʻawi i kahi kuhi i ka palapala 'āina maʻamau

1. Hoʻomaka mākou i kahi kaha kiʻi

2. Ke hoʻohana nei i ka "map classic" workspace, hele mākou i ka palapala 'āina / mea hana / hāʻawi i ka ʻōnaehana hoʻonohonoho honua. Ma kēia ala ua loaʻa i kā mākou dwg kahi ʻōnaehana kuhikuhi, nui ka poʻe ma ʻaneʻi i hewa no ka mea hāʻawi wale lākou i ka ʻōnaehana hou, kahi e hewa ai ka ʻikepili. Ma ke pihi "select coordinate System" koho mākou i ka ʻōnaehana kumu.

3. Ma kēia laʻana, loaʻa iaʻu kahi palapala ʻāina ma NAD27, no laila koho mākou i kēia ʻōnaehana ma ka pihi "select coordinate system"; Makemake au e hāʻawi i kēia iā NAD83, hāʻawi wau iā ia i ka pihi aʻe ma ka papa like (ke kiʻi kumu). Me ke pihi "koho kiʻi", koho ʻia ka faila (a i ʻole nā ​​​​faila) e hana hou ʻia.

4. I kēia manawa he pūnaewele hoʻonohonoho ko kā mākou palapala ʻāina, wehe mākou i ka papa hana inā ʻaʻole ia e hoʻoheheʻe ʻia. Hiki ke hana ʻia me ka pā kauoha MAPWSPACE, a laila komo.

5. I kēia manawa mai ka "map explorer", kaomi pololei mākou i nā "drawings" a koho i ka "attach"

6. ʻO ka pahu kamaʻilio e hōʻike ʻia e hiki iā mākou ke ʻimi i ka polokalamu kele no ka faila kumu, ke loaʻa iā mākou e hoʻopili i ke pihi "add"

7. Me ke kaha kiʻi i hoʻohui ʻia, e hoʻonohonoho ana mākou i kahi nīnau. No ka hana ʻana i kēia, kaomi pololei mākou i ka "nā nīnau o kēia manawa" mai ka papa kuhikuhi palapala palapala, a koho i ka "define".

8. Mai ka Huli panel hualoaʻa, kaomi ma luna o "wahi", ma lalo o "query type", a laila kaomi "ok" e 'ae i "nā palena āpau". ʻO kēia ka manaʻo inā e hele mākou e nīnau i ke kiʻi kumu i loko o kāna mau hui, me ka "ʻano nīnau" i wehewehe ʻia, koho mākou i ke koho "draw" ma ke ʻano he "query mode".

9. Ma hope o ka wehewehe ʻana i ka nīnau, kaomi mākou i ke pihi "hoʻokō i ka nīnau". Ke hoʻopau ʻo AutoCAD Map 3D i ke kaʻina hana, hana mākou i kahi ākea ākea a hiki iā ʻoe ke ʻike i ke kiʻi kiʻi hou ʻia.

Ua mea i olelo ia i kekahi mau mea Kanawai 3D i makemake i ka hoʻoneʻe i oluolu ke kumukuai, e like me ka mea i ka hihia o ka luna 'mau mea e kukaʻi (mau kii, he moolelo) a me ka poe e noho ana e like mokupuni (mau mea e kukaʻi loko mau mea e kukaʻi); a i topologically kukuluia me kaʻino like smartline a me nā aberrations. Ka mea, e nui ālai 'a me nā pūʻulu e pono e e exploited mua reprojection.
