Down alanui palapala 'o Google Earth

I ko mākou ʻike, ʻaʻohe polokalamu (akā) hiki ke hoʻoiho i nā alanui o Google Earth i ka palapala vector. ʻOiai hiki iā ʻoe mai ka Open Street Maps, maikaʻi ʻole mai nā kūlanakauhale āpau.

Akā inā hoihoi kekahi i nā alanui o Google Earth, a laila ke ala i waho e hoʻoiho iā lākou ma ke ʻano he kiʻi, a laila vectorize e like me gehena ma luna o lākou. Eia kekahi mau ʻōlelo aʻoaʻo e hoʻēmi i ka pae o ka hanaʻino:

1. E kau i kahi kiʻi kiʻiʻeleʻele

Hana mākou i kēia, i ʻole e keakea ke kiʻi ukali a hoʻomaikaʻi i ka ʻike o nā alanui. Hana ʻia kahi kiʻi bmp ʻeleʻele i Mspaint a kāhea ʻia mai Google Earth, e hohola ana ma luna o ka wahi hoihoi.

2. E kiʻi i ke kiʻi me Stitchmaps

E hoʻohana nei StitchMaps, koho mākou i he mosaic e hiki ai iā mākou keʻike i nā kikokikona o ka mānoanoa ma lalo o ka kiʻi o ke alanui.

Eʻike i keʻano, ināʻaʻoleʻo Google Earth iʻike i nā alanui āpau o ke kiʻi,ʻo Stitchmaps nā mea a pau, koho mākou i kahi haʻahaʻa haʻahaʻa, ma kēia hiʻohiʻona 384 mika.

Ke wehewehe ʻia ka mosaic, kauoha mākou e hoʻoiho, a kali i ka mosaic e kūlike. ʻO ka hopena mālama mākou iā ia me ka format tiff, a me kahi faile hoʻoponopono no OziExplorer (.map). Penei ke kiʻi: ʻo ke kiʻi ma ka ʻākau kahi hoʻonui:

Ma keʻano kuhi, inā makemake mākou e hoʻololi i ka .ecw, i Laulā Mapper lawe mākou iā ia i loko, hāʻawi i ka wanana a haʻi iā ia e hoʻoponopono iā ia mai kahi faila .map. A laila hiki ke hoʻokuʻu ʻia aku i .ecw no ka mālama maikaʻi ʻana mai kahi papahana ʻē aʻe.

3. E nānā iā ia me ka papa hana hoʻopili

ʻO ke laina laina ma ka laina e hiki ke hoʻonui i ka hoʻonāukiuki, inā makemakeʻoe e holo wikiwiki, hiki iāʻoe ke hoʻohana i ka polokalamu hoʻolālā polokalamu, e like me Microstation Descartes.

Ua hoʻomaopopoʻia ua kiʻiʻia ke kiʻi .ecw ((inā hiki ke hanaʻia mai Descartes), he aha ka mea e hele mai e hoʻololi i ke kiʻi i kahi vector, me ke ʻano hana like a mākou e hōʻike ai ma kahi i hoʻouna muaʻia.

Hana ʻia kahi mask no nā kani melemele, a ʻo kekahi no nā kani hina a laila haʻi mākou iā ia e hoʻololi iā lākou i kahi vector me ka hoʻomaʻemaʻe topological. ʻO ka ʻāpana kahi o ka huaʻōlelo e hana ʻole ai i ka vector, pono mākou e hana i ka uniona ma ka wāwae, ʻoiai inā makemake ʻoe e hoʻohana maikaʻi iā Descartes, hiki paha iā ia ke hoʻololi i kēlā mau leo ​​o ka huaʻōlelo i ka hina o ke alanui, ʻo ia ke kumu. ua hana mākou i mea liʻiliʻi. Inā makemake ʻia e kikokiko ʻia ka huaʻōlelo, e hoʻohana i ke kauoha no nā huaʻōlelo oriented.

4 Inā loaʻaʻole Microstation Descartes

Pono e hana like me AutoDesk Hana Raster, 'O ArcScan, nui loa GIS, a me Corel Trace.
