Kuhi i nā kikowaena mai Excel a QGIS a hana Polygons
ʻO kekahi o nā hana maʻamau i ka hoʻohana ʻana o Geographic Information Systems ʻo ia ke kūkulu ʻana i nā papa spatial mai ka ʻike mai ke kahua. Inā hōʻike kēia i nā kuhi, nā pākeke ʻāpana, a i ʻole ke kaha kiʻekiʻena, hele pinepine ka ʻike i nā faile hoʻokaʻawale a i ʻole nā papahā Excel.
1. ʻO ka faila hoʻonohonoho ʻāina ma Excel.
Ma kēia hihia, ke ho'ā'o nei au e ho'okomo i nā noho kanaka o ka Repubalika o Cuba, ia'u 'o Diva-GIS, ʻo ia ma ke ala kekahi o nā pūnaewele maikaʻi loa e hoʻoiho i nā ʻike ʻāina mai kēlā me kēia ʻāina. E like me kāu e ʻike ai, aia nā ʻaoʻao B a me C i ka ʻikepili e pili ana i ka latitude a me ka longitude i ke ʻano o Nā kūlana kaiapili.
2. Hoʻokomo i ka faila i QGIS
No ka ho'okomo i nā kikowaena o ka faila Excel, ua hana'ia:
Vector> mea hana XY> OpenExcele faile ma ke ʻano he papa ʻaina a i ʻole ʻāpana Point
Inā mālama ʻia ka faile me ka .xlsx extension, ʻaʻole e hōʻike ʻia ka polokalamu kele pūnaewele, no ka mea kānana wale ia i nā faila me kahi extension .xls. ʻAʻole ia he pilikia, hiki iā mākou ke noi i nā ʻenehana DOS kahiko a kākau i ka hoʻololi inoa, ka kānana. *. * (asterisk dot asterisk) a komo mākou i; e ʻae kēia i nā faila āpau i kēlā wahi e ʻike ʻia. Ua hiki iā mākou ke kākau wale i ka * .xls a e kānana wale ʻia nā faila me ka .xls extension.
A laila, loa'a iā mākou kahi papa e pono ai mākou e kuhikuhi i ke kolamu e pili ana i ka coordinate i X, ma kēia hihia e koho mākou i ke kolamu o ka lō'ihi, ke paepae o latitude no ka kuhikuhi Y.
A ma laila mākou e loaʻa ai. Hōʻike ka nīnau ua mālama ʻia ka papa me ka ʻikepili i loko o ka faila hoʻonohonoho kanaka o Cuban, kahi e komo pū ana ka inoa, ka latitude, ka longitude, ka hoʻonohonoho ʻana, a me ka panalāʻau hoʻomalu.
3. Hana i nā polygons mai nā kaulike
I ka hihia, makemake mākou'a'ole wale e ho'okomo i nā po'omana'o, akā, e hana i kekahi polygon i loko o ka papa o kēia mau kuhikuhi, hiki iā mākou ke ho'ohana i ka mono Memo2One. ʻAe kēia plugin iā ʻoe e ʻike pehea e kāhea ʻia ai ka papa huakaʻi, inā e kūkulu ʻia ka mea a mākou e lawe ai i laina a i ʻole polygon.
4. Pehea e lawe ai i nā kikowaena mai Excel i nā papahana CAD / GIS ʻē aʻe.
E like me kāu e hoʻomanaʻo ai, ua hana mākou i kēia hana me nā papahana ʻē aʻe. Maʻalahi e like me QGIS, kakaikahi. Akā eia pehea e hana ai me AutoCAD, Microstation, nui loa GIS, AutoCAD Kanawai 3D, Google Earth.
