Ngenisa izixhumanisi kusuka ku-Excel kuye ku-QGIS bese udala ama-Polygon
Enye yezindlela ezijwayeleke kakhulu ekusetshenzisweni kwe-Geographic Information Systems ukwakhiwa kwezingqimba zendawo yolwazi oluvela emkhakheni. Noma ngabe lokhu kumela izixhumanisi, ama-vertices wephasela, noma igridi yokuphakama, imininingwane ngokuvamile iza ngamafayela ahlukaniswe ngokhefana noma amaspredishithi e-Excel.
1. Indawo ihlela ifayela ku-Excel.
Kulesi simo, ngizama ukungenisa ukuhlala kwabantu kweRiphabhlikhi yaseCuba, engilanda kuyo diva-GIS, okuyindlela ngenye yezindawo ezinhle kakhulu zokulanda idatha yezwe kunoma yiliphi izwe. Njengoba ukwazi ukubona, amakholomu B no-C aqukethe imininingwane maqondana nobude nobude ngendlela ye- izixhumanisi zendawo.
2. Ngenisa ifayela ku-QGIS
Ukungenisa izixhumanisi zefayela le-Excel, kwenziwa:
Vector> XY amathuluzi> Ifayela le-OpenExcele njengethebula lesichasiso noma ungqimba lwePhoyinti
Uma ifayili ligcinwa ngesandiso se-.xlsx, isiphequluli ngeke silikhombise, ngoba lihlunga kuphela amafayela ane-.xls extension. Akuyona inkinga, singasebenzisa amasu amadala we-DOS bese sibhala ekushintsheni kwegama, isihlungi: *. * (i-asterisk dot asterisk) futhi senza u-Enter; lokhu kuzovumela wonke amafayela akuleyo ndawo ukuthi abonakale. Besingavele sibhale * .xls futhi bekuzohlunga kuphela amafayela ane-.xls extension.
Khona-ke iphaneli ibonakala lapho kufanele sibonise ukuthi iyiphi ikholomu elilingana ne-X yokuxhumanisa, kulokhu sikhetha ikholomu yokude, ikholomu ye-Y coordinate.
Futhi lapho sinakho. Umbuzo ukhombisa ukuthi ungqimba lulondoloziwe ngemininingwane equkethwe kufayela lokuhlalwa kwabantu laseCuba, okubandakanya igama, i-latitude, i-longitude, ukuhlukaniswa, kanye nesifundazwe sokuphatha.
3. Dala amapholigoni amaningi ngezixhumanisi
Uma kwenzeka, asifuni ukungenisa kuphela ama-vertic kodwa futhi sakha i-polygon ngokulandelana kwalezo zixhumanisi, singasebenzisa i-plugin Amaphuzu2One. Le plugin ikuvumela ukuthi ubone ukuthi ungqimba lapho uya khona luzobizwa kanjani, uma lokho esizokungenisa kuzokwakhiwa njengemigqa noma njenge-polygon.
4. Ukungenisa kanjani ukuxhumanisa kusuka ku-Excel kuya kwezinye izinhlelo ze-CAD / GIS.
Njengoba kungenzeka ukhumbule, le nqubo siyenze nezinye izinhlelo eziningi. Elula njenge-QGIS, bambalwa. Kepha nansi indlela yokukwenza ngayo AutoCAD, I-Microstation, GIS ezininginingi, I-AutoCAD Civil 3D, Google Earth.
