Ngenisa isithombe se-Google Earth kwisakhiwo se-ecw

Isidingo: Sisebenza i-cadastre sisebenzisa isithombe se-Google Earth ngefomethi ye-georeferenced engasindi.

Inkinga: I-ortho elandwa yiStitchmaps ikufomethi ye-jpg, i-georeference eyilethayo ayisekelwa yi-Microstation.

Isixazululo: Landa isithombe nge-Stitchmaps, vumelanisa iGoogle Earth neMicrostation ukungenisa ukubanjwa kwe-georeferenced bese ugoqa omunye komunye.

Sinesithakazelo ku-ecw ngoba ayihlali kwifayela elengeziwe futhi lapho i-200 MB HMR noma iTiff ingalinganisa i-12 MB kuphela ngaphandle kokulahlekelwa yikhwalithi eningi. Sine-Stitchmaps ne-Microstation PowerMap V8i, njengoba sinakho sizokwenza ngalokhu yize ngezinye izinhlelo kungenziwa ngezinyathelo ezimbalwa.

Ake sibone ukuthi kwenziwa kanjani:

1. Ukulanda isithombe. 

Senze lokhu ngalokhu I-Stitchmaps, njengoba sekuchaziwe ngaphambili. Ngaphandle kokuthi sidwebe unxande kuGoogle Earth, ukuze ifakwe ekufakweni kwezithombe.

Ku-Google Earth lokhu kwenziwa nge Faka> i-Polygon, futhi ngesitayela sikhetha uhlaka ngobukhulu bomugqa ongu-1.4 omhlophe. Sizokwenza kanjena, ngoba iMicrostation ayikwazi ukungenisa ifayela le-kml kulezi zinguqulo, ngaphandle kwe-FME evela eBentley Map. Kepha inguqulo I-Powermap akulethi lokhu kusebenza, ngakho-ke ukudala umugqa kufanele siwenze ngokudweba esithombeni.

I-2. Dala i-dgn georeferenced.

Lokhu kudalwe ngokwenza Ifayela > Okusha, bese sikhetha imbewu ye-Seed3D. Ukungenisa isithombe kweGoogle Earth akusebenzi kufayela le-2D.

Khona-ke kumelwe sengeze i-georeference efayeleni, eyenziwe nge: Amathuluzi> Ukuma Kwendawo> Khetha Uhlelo Lokuxhumanisa

Kwiphaneli esiyikhethayo Kusuka kulabhulali, futhi kusukela manje sinesithakazelo ku-UTM 16 North, sikhetha:

Umtapo Wezincwadi> Iphrojekthi> Umhlaba (UTM)> WGS84> UTM84-16N

Uma lolu uhlelo esilusebenzisa kakhulu, singachofoza kwesokudla bese sengeza kuzintandokazi, ukuze sikwazi ukufinyelela kalula. Senza OK futhi kakade ifayela lethu liyi-georeferenced.

3. Thwebula isithombe kusuka ku-Google Earth

Ukuvumelanisa i-Microstation ne-Google Earth esenzayo Amathuluzi> I-Geographics> Landela i-Google Earth View. Ngale ndlela, ukubuka kwethu kukhombisa lokho okukuGoogle Earth. Kuyinto elula ukuthi ubhekise enyakatho lapho kanye nendlela eyamukelekayo.

Ukungenisa isithombe esenzayo Amathuluzi> I-Geographics> Thatha isithombe se-Google Earth, sichofoza esikrinini bese siqedela ukuthunyelwa. Lokho esinakho lapho akusikho isithombe, kepha a imodeli yendawo ye-digital, ngesithombe njengempahla yezicathulo.

Ukubona isithombe, siqalisa ukunikezwa. Ukuze ungafaki inkinombo lapho izinkinobho zokunikezela zikhona, ngizozisebenzisa ngomyalo wombhalo. Izinsiza> Ukhiye ku> unikeze konke okushelelayo.  Bona ukuthi kukhona ibhokisi elisithandayo. Lesi sithombe, yize sinesinqumo esingesihle neze, sikhonjisiwe.

4. Ukubheka isithombe

Ngalokhu, okokuqala, sizokwakha amaphuzu emakhoneni wesithombe esichazwe georeferenced. Lokhu kwenziwa ngomyalo wamaphoyinti, sizowenza abe luhlaza okotshani, aqine ukumela futhi abe nendlela efanelekile yokuthi ikhoneni likanxande libonakale. Uma silahlekelwa isithombe, senza umyalo wokunikeza futhi, futhi asikhathazeki ngokuthi siqonde ngqo, siyakhumbula ukuthi ukunemba kwe-Google Earth Kuyingozi kakhulu kunalokho esikulahlekelwa lapha.

Uma nje amaphuzu enziwe, sifaka isithombe se-jpg esilandile nge-Stitchmaps:  Ifayela> Umphathi weRaster, khona-ke kule iphaneli esiyikhethayo Ifayela> unamathisele> Raster. Masingakhohlwa ukushiya inketho isebenza Beka ngokuhlanganyela, ngoba sizoyifaka ngesandla.

Sibeka ngaphakathi ebhokisini lesithombe esiyimpunga, ukuze sikwazi ukusilula kusuka lapho. 

Ngendlela efanayo, senza amaphuzu emakhoneni onxande asemfanekisweni wombala. Lokhu sizokwenza ngokubomvu ukubona umehluko.

Ekugcineni kufanele sibe nalokhu:

Ukuze welule isithombe, kusuka ku-Raster Manager iphaneli, chofoza ngokuqondile esithombeni, sikhetha Warp, ngendlela I-Affine amaphuzu angaphezu kwamathathu. Ngemuva kwalokho sikhetha ikhona ngalinye, okukhombisa iphuzu lendabuko (obomvu) endaweni okuyiwa kuyo (okuluhlaza) kuthi uma bonke bekhona, sichofoze kwesokudla igundane.

5. Guqula isithombe sisuke ku-jpg siye ecw

Kwenziwe, manje isithombe sethu se-jpg senziwe nge-georeferenced. Ukuyigcina ngenye ifomethi, khetha, chofoza inkinobho yegundane kwesokudla bese ukhetha igcine njenge. Singakhetha kumafomethi amaningi, kufaka phakathi okuyigugu ecw okungenalo izinguqulo ze-Microstation. 

Futhi ekugcineni sinezinto esizidingayo, i-raster 24 MB ngobukhulu, nebhokisi lesithakazelo sethu samamitha angu-1225 ngakunye, silungele ukusebenza.
