I-georeferencing imephu ye-dwg / dgn

Sizosebenzisa lo msebenzi ukuze sichaze ukungabaza endleleni endleleni yokwabela ngayo imephu e-CAD.

Sizosebenzisa isibonelo okwakhiwe ngaphambili, lapho sakha khona uhlaka lwe-UTM lwendawo ye-16 enyakatho kusuka kushidi elivelele futhi wakhe nge-AutoCAD.

I-1. Izinyunithi

Lena yinkinga enkulu lapho isebenza nethuluzi elivamile le-CAD. Endabeni ye-AutoCAD, izingxenye zomsebenzi ziyinkimbinkimbi ukusingatha abantu abafayo kuphela, ngoba uma kufakwe okokuqala futhi kubulawa, ibuza: Ingabe uyi-gringo? ... Awukho lokho okuluhlaza kodwa ubuze ukuthi uzosebenzisa amayunithi ngamamitha noma amayintshi.

Iqiniso ukuthi emazweni ethu aseSpanishi iyunithi yimitha, ukuze umhlaba ube yinkimbinkimbi kithina, okungathi ngezinhloso zokwakha kungabaluleki (amayunithi ngamayunithi) ... nokungabaluleki okuthile lapho kulayishwa amabhlogo noma izitayela imigqa idinga ukukalwa kabusha. Futhi noma izinguqulo zakamuva ze-AutoCAD zisiza kule nkinga, amafayela enziwe ngezinguqulo ezindala agcina inkinga yamayunithi lapho ufuna ukuqondisisa.

Endabeni ye-Microstation, lokhu kuhlelwe ku- "amayunithi asebenzayo” kodwa ngendlela efanayo baqhubeka bengamafayela e-cad ngaphandle kwe-georeference. Unokulawula okungcono kulokho i-Microstation ekubona njengefayela lembewu (ifayela lembewu), lapho konke lokho kulungiselelwa kuchaziwe ... ukuthi yize kubuhlungu ukuqonda ekuqaleni kusiza kakhulu kunamathempulethi e-Anglo-Saxon AutoCAD.

Masikhumbule ukuthi uma usebenza nezixhumanisi ze-UTM, futhi imephu "i-georeferenced" kwenye yalezo zixhumanisi, onakho yifayela elinereferensi ehlobene negridi, kodwa alikabi nayo i-projection noma i-Datum, Yilokho esetshenziselwa kona. Kwaziwa ngokuthi i-georeference noma ireferensi ephelele.

Endabeni yami, "ukuze kungabi yinkimbinkimbi" ngamayunithi we-AutoCAD, engikwenzayo ukuvula imephu yezwe lami ku-Microstation, engikwaziyo ukuthi i-georeferenced, ngibiza ifayela le-AutoCAD njengereferensi (ngoba ayidingi ukungenisa. ) bese ukhetha inkinobho "Izinketho ze-DWG" lapho ngicacisa ukuthi izingxenye zomsebenzi zikhona "seed file master units", futhi ikakhulukazi Indlela yokunamathisela ake kube njalo "I-Coincidence World". Futhi, akunandaba ukuthi i-dwg yasebenza ngamamitha noma amayintshi, ifayela liyabona izingxenye zomsebenzi ze-map dgn yami, bese ngibhala imephu yereferensi efayeleni lami futhi ngiyigcine ngegama elinye, ngaleyo ndlela ngiyazi ukuthi Imephu inezici zefayela lami lembewu.

… Kulungile, inkinga yami kodwa iyangisebenzela… ungazitholela eyakho ukuhlanekezela 🙂

I-2. Nika iProjection

Okulandelayo kulula, ungenza okuningi ngakho ezininginingi, noma ngabe une-parrot emhlane wakho okufanelekile i-$ 1,500 ungayenza futhi ArcGIS :), okufanayo I-Map3D, Microstation I-Geographics, Cadcorp...

Ukuze ukwenze nge-Manifold udala ifayela elisha, bese ungenisa ifayela le-CAD “ifayela / ukungenisa / ukudweba", ukhetha inketho yefayela elithi "dgn". Ikucela ukuthi ukhethe amasegimenti ejika, lapho wamukela khona inani eliza ngokuzenzakalelayo.

Khona-ke ifayela elingenisiwe, ngisusa iphuzu nemigqa emibili engingazi ukuthi kungani zidalwe. Ngalokho uyakwenza nje"thinta futhi ususe“… uyadlala bese ususa ngokhiye othi “susa” 🙂

Ukuze unikeze ukuqagela, khetha ingxenye, inkinobho yegundane kwesokudla bese ukhetha "ukunikeza ukuqagela"

Khumbula ukuthi awukwazi ukukhetha "ukushintsha ukuqagela" ngoba kuyifayela le-cad, elingenakho ukuqagela.

Endabeni yami ngizokhetha “Universal Traverso Mercator”, Zone 16 Northern Hemisphere kanye ne-WGS84 njenge-Datum.

I-3. Thumela ku-Google Earth.

Lena indlela enhle yokuhlola ukuthi imephu ine-georeferenced kahle, ngakho-ke ngizoyithumela ku-kml (asikho isidingo sokuyabela ukuqagela kokudidiyela kwendawo). Chofoza kwesokudla engxenyeni eseyivele ikhona bese ukhetha inketho "yokuthekelisa", ukhetha ifomethi ye-kml.

Ukwakha izindawo ezihlukene, umane wenze ikhophi yento (ngaphandle kokuba ne-georeference okwamanje), bese unamathisela, unamathisela, unamathisela, unamathisela, unamathisela, unamathisela, unamathisela, unamathisela ... bese unikeza izindawo ezihlukene entweni ngayinye edaliwe. (Into ehlanganisiwe ilingana nohlaka)

Kamuva uvule amafayela we-kml ngeGoogle Earth, ushintshe ubukhulu nombala womugqa ... futhi lapho unezindawo ezisuka eMexico ziye eVenezuela nalezo zaseSpain.

Kusuka lapha ungalanda amafayela alo mkhuba ngamafomethi.DWG,.DGN V7 ,.imephu yezinto eziningi futhi.KML kanye nezindawo ze-utm zenyakatho yezwe lamazwe aseSpanishi, kuhlanganise nezintathu ezisebenza eSpain

… Konke kuthathwe kufayela elilula le-dwg ekwakhiwe nge-Excel.
