Zifanele kangakanani izithombe ze-Google Earth
Udaba lokuhlolwa kwesifo ukunemba nezithombe zesiphuphutheki futhi orthorectified ye-Google Earth umbuzo irekhodi ku izinjini kulezi zinsuku ukudida ngokunemba ukubekezelelana kulula njengokuhlola kokulahlekelwa GPS cab, kungaba kuhle ukukwenza ambalwa ukuhlaziywa yini noma cha ukusebenzisa le datha umsebenzi sína.
Muva nje I-DigitalGlobe, umhlinzeki wezithombe ze Google Earth, umemezele ukuthi maduzane bazothola izinto eziningi emva kokuqaliswa kwesathelayithi entsha yesinqumo esiphezulu kanye nokukhishwa okukhulu ngosuku.
Le satellite ibizwa Ukubukwa kwezwe I, Yikuphi ezosebenza ngokuhlanganyela satellite Quickbird, izithombe abe pixel ukulungiswa 50 amasentimitha (okwamanje 1 imitha) futhi kungaba thatha 600,000 amakhilomitha square ngosuku, okuyinto okwamanje etholwe ngesonto.
Lokhu kuvame ukudukisa labo abagxila kuphela kumkhiqizo wokugcina (amamephu) hhayi kwimikhiqizo yocwaningo oluphakathi nendawo kanye nemvelaphi yabo ye-photogrammetric, okuyikho okusivumela ukuthi singabi nemikhiqizo kuphela kepha nezinga labo lokunemba nokubaluleka. Lapho usebenzisa okokusebenza kweGoogle Maps ngezinhloso zendawo Ukunemba okuphansi kungafakazelwa, kwesinye isikhathi kuze kufike kumamitha angama-30, ngoba isithombe sesethelayithi sidinga inethiwekhi eminyene yoku-oda kuqala namasheke asendaweni okulungiswa. Akukona ukuthi kubi, kungenxa yokuthi kwenzelwa i- iwebhu okuyiyona ndlela i-Google Earth ibiza ngayo leyo ngqimba.
Kulabo abafuna ukwenza i-cadastre nge-ortos yeGoogleEarth, nasi isibonelo salokho okuzotholakala:
Yilokho I-Jaguita, i-Comayagua, Honduras; qaphela indlela ukuphindaphinda kwezakhiwo eziyinkimbinkimbi efanayo, amamitha angu-36.51 kuya enyakatho-mpumalanga, kubonakala kumbuthano wesithombe.
Sisebenzisa ezimbili GPS Magelan Ucingo semephu, besisekelo esisodwa, omunye ngoba ephakamisa amaphuzu bese enze ukulungiswa umehluko, uma kuqhathaniswa orthophoto isithombe zasemoyeni wadala eminyakeni emithathu edlule nge indiza 5,000; idatha ye-GPS ihambelana ngokuphelele ne-orthophoto kodwa hhayi ngemifanekiso ye-Google Earth, enye yazo i-23 metres esenyakatho-mpumalanga, enye emamitha angu-19, kodwa i-vector vector ine-angle ehlukile.
Mayelana nalokhu, akunakwenzeka ngathi ukuthi singabaze uhlelo, olungcono kakhulu abantu bethu abaningi abangaba nalo lapho imininingwane ye-cartographic ingeke ifike eminyakeni eyishumi ezayo nokuthi ukuyikhipha kumahhala; into ebalulekile ukuthi siyazi ngokuhambisana kwayo nemikhawulo.
Ukuze uzindle ngikushiyela leli phuzu lemigomo ye-Google Earth, leyo okungekho muntu oyifundayo futhi ecindezela kuphela inkinobho ethi "Ngiyamukela":
e) CHA ISELULEKO NOMA ULWAZI, kungaba ngomlomo noma lebhaliwe, etholwe KUSUKELA KU-GOOGLE NOMA UMUNTU WESITHATHU noma ngokusebenzisa SOFTWARE OKUYOTHI DALA YILUPHI ISIQINISEKISO HHAYI NGOKUCACILE ezishiwo migomo nemibandela.
Ngithemba ukuthi okuhlangenwe nakho kuzoba wusizo kumuntu othile: Ngenze inhlolovo yamahektha ayi-14 nge-gpsmap 64sx, ngothi, kulokhu izixhumanisi zazicishe zibe ngamamitha angu-1.5 wokunemba ku-planimetry (akunconyiwe ku-altimetry), ukuze ngibe nedatha enembe kakhudlwana engiyilinganise. imingcele (hhayi yonke ngenxa yokuthi bekunezingxenye ezinamaxhaphozi) futhi ixhumanisa amaphuzu angenasizathu nezilinganiso futhi ulungise izixhumanisi ku-ch. ngakho-ke imingcele yephutha incishiswa ibe ngamasentimitha, angikwazi ukuchaza inqubo ngokuningiliziwe njengoba izoba yisicefe kakhulu, ngithemba ukuthi izokusiza.
Qaphela: uhlobo lwe-GPS navigator ku-topography lusetshenziselwa ukuba nezixhumanisi cishe.
I-RTk gps ingamadivayisi akhethekile, anomkhawulo wephutha we-milimetric.
Ngiyakutshela ozakwethu, i-google Earth inamaphutha amaningi nokuningi ezindaweni eziphakeme, bengiphakamisa nesiteshi futhi umkhawulo wephutha lalokhu maqondana nokuphakama kwami wawucishe ube ngamamitha ayi-8 kuphrojekthi lapho imitha elilodwa ngaphezulu noma elingaphansi lingadala umsele ohlulekayo endaweni eyisicaba, sicela uphumule ukubona wonke lawa mazwana ngiyabonga.
Azisoze zafana nawe. Imodeli yokuphakama yeGoogle Earth yenziwe lula kakhulu njengoba kungokwenhloso yomhlaba jikelele; okungenzeki lapho wenza inhlolovo yendawo enamaphuzu amaningi wokulawula ukuphakama.
Ngisanda kwenza ucwaningo ngesimo sendawo samanzi okuphuza e-Arequipa futhi amazinga engiwatholile neTotal Station awahambelani nhlobo namazinga noma imigqa ye-google Earth. Kunomehluko wamamitha angama-40 phezulu.
Kuyadingeka ukuba ichaze eziningi sub-imethrikhi kudidaniswe amatilosi GPS (Garmin, Magellan, njll) Akungabazeki ukuthi zikhona Sub-metrical ngokunemba cadastre ka 5 cm (okuyinto elikhulu) kuya iziphequluli kukhona ukungezwani phakathi 3- 5-10 amamitha.
Izithombe ze-Google kufanele zithathwe njengendlela yokubhekisela, kodwa hhayi njengesisekelo sokusebenza ngokucacile kwe-metric; ngoba futhi kuze kube yilapho beyiqinisekisa, ukuhluka kuzoqhubeka namadivayisi ahlukene wonke umuntu asebenzisa.
Phendula ngokucaphuna
EMexico iphutha lisuka ku-5 kuya ku-7 wamamitha, sengivele ngenze izivivinyo ezimbalwa nge-GPS engu-2. Kodwa-ke, uma usebenzisa umsebenzi we- "Geolocation" ku-Autocad, leli phutha liyancipha ngokucabangela iphutha le-GPS kuphela, ngokusho kokuhlolwa engikwenzile kuze kube manje.
Kuyiqiniso ukuthi inhlolovo eyenziwe ngesiteshi esiphelele ayihambisani nanoma yini nge-Google images,
Kufanele uqinisekise ukuthi usebenza kusiphi isam, imvamisa isebenza ku-sam 84 okuyiyo esetshenziswa emhlabeni wonke, ngoba lokho kwenza umehluko wephuzu elilodwa.
Zisuka ku-7 kuye ku-10 metres app, ngiyakutshela ngokuya ngomsebenzi wami ngoba ngisebenzisa kakhulu i-GPS namashadi ezempi futhi lapho kukhombisa umehluko.
Namuhla ngazithola nginokungabaza okufanayo futhi ngifuna ukucaca okuphezulu kakhulu ekubikeni kwedatha, futhi umehluko emininingwaneni kakhulu kakhulu okwenza ngisolise kakhulu. umehluko wesilinganiso nge-GPS ne-google ingaphezu kwe-5 km futhi okukhathazayo
Ungalisebenzisi IZIHLOKO EZILUNGILE
Izixhumanisi ze-Datum ze-UTM ezisetshenziswa yiGoogle Earth yi-WGS84, futhi umehluko ubangelwa ukuthi i-GPS oyisebenzisayo ihlelwe ku-Datum NAD 27. Lungiselela i-GPS yakho, ngiyayincoma. Ukubingelela okuvela eManagua, eNicaragua.
Akulutho kangako ukusho ngokunemba. Hhayi ukukalwa kwamaphasela, ngaphandle kokuthi ukusetshenziswa kungokwezimali kuphela noma akuhlanganisi insiza esemthethweni.
Sawubona, ukuphawula okuthakazelisayo kakhulu. Siyazisa i-Google Earth mahhala, kodwa ngicabanga ukuthi uma umuntu edinga okuthile ngokucacile, ngaphandle kokutshala imali enkulu, ngingasebenzisa i-GPS, ehlinzeka ngokucacile ngamamitha amathathu noma angaphansi kwamamitha amathathu. Sicela othile angitshele uma ukuphawula kwami kuyiqiniso, ngoba ngivame ukufuna ukunemba ekutholeni amaphuzu. Ngaphambi kwesikhathi, ngiyabonga.
Lapho ngiqala ukusebenzisa iGoogle Earth ne-GPS nginenkinga efanayo, isixazululo ukuthi kokubili kufanele kube ohlelweni olufanayo lokuxhumanisa.
Ngalokho kuzoba nzima kuwe ukusebenzisa isithombe seGoogle. Yebo, kuye ngezwe nendawo lapho ukhona, uhambo luhlukile.
Mhlawumbe enye indlela ukuthi ulanda isithombe nge-Plex.Earth, nokuthi uthatha amaphuzu okulawula ukuze ulungise noma ngaphezulu ukulungisa izimpendulo ezamukelekayo.
Ngizinikele ekuzulazuleni ezimotweni ezingama-4 × 4 futhi sihlala sisebenzisa i-Garmin GPS, bengifuna ukuyixuba nezixhumanisi zeGoogle futhi nginokuhluka okufika kumamitha angama-200 phakathi kwesithombe nephuzu eliqondile ukuze kungithinte kakhulu ukukuthola izikhala futhi empeleni i-waypoint, ngingasenza kanjani lesi sikwele noma yiziphi izinhlelo engizisebenzisayo nezithombe ze-satellite ukuze ngibe nokuhluka okuncane? Ngifuna ukuphatha ngedatha, izithombe kanye nezixhumanisi ngesikhathi sangempela.
imikhonzo!
Yebo, lesi sixhumanisi sisho okuthile

Sawubona futhi
Okokuqala siyabonga impendulo, mina ofakwe abanye ulwazi samanje ezincwadini zenu ezihlukahlukene ezweni, ngicabanga ukuthi uzobe nzima ukusebenzisa i-Google Maps lokusebenzisa umhlaba ngakho mina aqinise ukufuna omunye izixazululo uma umuntu lapha wazi ezinye izindlela engingazibonga njengoba ngifuna isisombululo sokuxazulula inkinga ehambisana ne-cadastre.
A ukubingelela.
Sawubona Everardo
Lokho kuya ngendawo yokuhlala. Isibonelo, e-United States nakwamanye amazwe ase-Europe, isithombe osibona ku-Google Earth sinikezwe yizifundazwe noma ohulumeni. Ngakho-ke ukunemba kuhle kakhulu.
Kepha kwamanye amazwe, ukunemba kuphakathi kwamamitha ayi-10 kuye kwangama-30 okususwa kwezithombe. Lokhu kungafakazelwa ezinhlokweni eziphakathi kwesibhamu seminyaka ehlukile.
Ayikho inguqulo ekhokhelwayo ekunika izithombe ezingcono.
A ukubingelela.
Sawubona, usuku oluhle
Nginentshisekelo yokusebenzisa amamephu we-google, kumaphrojekthi ahlukene anezinto ezihlukile ezilindelwe, ngakho-ke nginentshisekelo yokwazi ukuthi inembe kangakanani noma ukuthi liphi izinga lephutha layo; Ngiphinde ngifisa ukwazi ukuthi ngabe kukhona uhlobo olukhokhelwayo olunembe kakhulu noma ngokumane lapho ngingathola khona ngalokhu.
Ngiyabonga kakhulu, ngiyazisa le ncwadi.
Ukubingelela
Sawubona, ngombono wami angicabangi ukuthi izixhumanisi ze-geocentric (k) kufanele zilungiswe, njengoba ngifunda lapho, kodwa kunalokho ..., ukufuduka ngenxa yokukhululeka okukhiqizwa ngumphumela we-parallax.
Yilande nge-Stitchmaps njenge-jpg ekuphakameni kwelanga akukho mkhulu kune-500 mts, nefayela layo lokulinganisa bese ulilayisha kusuka ku-Ilwis.
Uma i-Ilwis ingayifunde ifayela lokulinganisa uzodinga amaphuzu okulawula okufanele uyibheke kuyo.
Ngingayidlulisa kanjani isithombe se-google eart kuya ohlelweni lwe-3.2 engenangqondo futhi lokhu kunginika ithuba elihle ngokuvumelana nezixhumanisi.
I-athikili inhle kakhulu, kulokhu… iqiniso lokuthi ayinembile ayikwenzi kube kubi futhi njengoba bethi iyona ndawo kuphela lapho besinikeza khona izithombe “zamahhala” zokulungiswa okuphezulu kangaka. Ngisebenzise ezinye futhi ngikwazile ukuqinisekisa ukuthi iphutha liyakhula ezindaweni ezinezintaba noma nge-topography engalingani, kodwa ezindaweni eziyisicaba iphutha uma liqhathaniswa nedatha ye-GPS ye-navigator ayizange ihambisane kakhulu ... ngokunengqondo kuncike kakhulu enjongweni yokusetshenziswa, ngibheka ukuthi ukudwetshwa kwamabalazwe “kwendawo” kuyithuluzi elihle kakhulu elonga isikhathi esiningi namandla…ihlala ivikela ukwesekwa ngamaphoyinti amaningi okulawula umhlabathi ukuze ilungiswe.
Njengoba nje i-imeyili yami isho, into eyodwa ubumbeko lwesakhiwo futhi enye indawo yokwakheka komhlaba evela esikhaleni (okungekho ...) kepha i-photogrammetry evela esikhaleni kufanele ilungise izixhumanisi ze-geocentric ngokususelwa ekujikeni komhlaba, bona umehluko I-TOPOGRAPHY FLAT …… UKUVIKELWA KWOMHLABA… ngaphezu kwalokhu, umkhawulo wephutha lelensi isithombe esathathwa ngaso emkhathini, wonke amalensi awasicaba u-100% ugobile, ngakho-ke ilensi yamehlo ezinhlanzi, u-50 mm 200 mm noma usondeze lokhu incazelo kulapho litholwa khona iphutha elisesithombeni ngenhla futhi noma ngubani ozama ukwenza i-cadastre nge-google ukhohlisa umnikazi noma uhulumeni
I-gracias
Inkinga ukuthi ukushintshwa kwesigaba akufani, akugcini ngokuhamba ibanga elithile ngoba kulungiswa kwesinye isikhathi bese kubola kwenye. Ngiwasebenzisile, ngiwalanda nge-stitchmaps, bese ngiwaqondisa ngamaphuzu wokulawula amaningi ngisebenzisa iMicrostation Descartes ... futhi lokhu kubathuthukisa kakhulu ...
I-Google ihlela ukuhlanganisa izithombe ze-geoeye ... kepha kuze kube manje, izithombe zesathelayithi azinayo i-georeference enhle ngaphandle kokuthi zishayisane nezindawo ezanele zokulawula zendawo.
Angazi enye iseva yekhwalithi engcono (nge-google), yebo kunezinsizakalo ze-OGC ezivela kwamanye amazwe anikeza imininingwane yabo ngendlela yezinsizakalo zebalazwe lewebhu.
Esikhundleni sokungabi nalutho, akukubi. Kuma-cadastres anendlela yentela, ukusetshenziswa komhlaba…. kulungile kodwa hhayi i-cadastre enendlela esemthethweni, ezofaka phakathi ukunikezwa kwesihloko somhlaba…. kungaba nzima ukunikeza umuntu impahla, nokuthi lokhu kungamamitha angama-30 kusihloko sikamakhelwane
NGIBINGELELA KUQALA UKUBINGELELA UKUTHI YINI IMINININGWANE ONAYO NGOMSEBENZI OMUSHA WE-GOOGLE… NGIYAQONDA UKUTHI BAZOTHATHA INETWORK ENTSHA YEZITHOMBE. SEBENZISA IZITHOMBE EZIVELA KU-GOOGLE EMHLABENI NOKUTHI WENZA KANJANI UKUPHAWULA BANESINOKUVIKELWA KWAMANYE AMAMITHI KUNGALUNGISWA UKUZE KUHLANGANISWE NALOKHO ENGIKUDINGAYO KODWA NGIZOTHANDA UKWAZI UKUTHI KUKHONA NANYE ISERVER ENEZINGA ELINGCONO KAKHULU
