Ungalanda kanjani izithombe ezivela ku-Google Earth - i-Google Maps - i-Bing - i-ArcGIS Imagery neminye imithombo

Kwabaningi babahlaziyi, abafuna ukwakha amamephu lapho kukhonjiswa khona i-raster kusuka kunoma iyiphi ipulatifomu efana ne-Google, i-Bing noma i-ArcGIS Imagery, siyaqiniseka ukuthi asinankinga ngoba cishe noma iyiphi ipulatifomu inokufinyelela kulezi zinsizakalo. Kepha uma esikufunayo ukulanda lezo zithombe ngokulungiswa okuhle, yiziphi izixazululo ezifana nazo StitchMaps ukunyamalala, nakanjani isisombululo esihle kunazo zonke yi-SAS Planet.

I-SAS Planet, wuhlelo lwamahhala, lwemvelaphi yaseRussia, ekuvumela ukuthi uthole, ukhethe futhi ulande izithombe eziningi ezivela kuzingxenyekazi ezahlukahlukene noma amaseva. Ngaphakathi kwamaseva, i-Google Earth, i-Google Maps, i-Yahoo, i-Bing, i-Nokia, i-Yandex, i-Navitel Amamephu, i-VirtualEarth, i-Gurtam ingatholakala futhi kungembiwa esithombeni, njengamalebula noma izakhiwo zomgwaqo - lokho okubizwa ngokuthi yi-hybrid- . Phakathi kwezindaba zayo, ungabhala:

1. ube isicelo esiphelele ngokuphelele, akudingi ukufakwa kwanoma yiluphi uhlobo, nje ngokukwenza lokho kungenzeka ukuba ufeze noma iyiphi inqubo,
2. kungenzeka ukufaka amafayela we-KML,
3. ukulinganisa kwamabanga nemigwaqo
4. umthwalo wedatha eyengeziwe evela kwamanye amaseva afana ne-Wikimapia,
5. Ukuthekeliswa kwamamephu kuya kuma-mobiles, kuyahambisana namapulatifomu afana ne-Apple - iPhone.

Ngesibonelo esisebenzayo, kuzokwenzeka ukubona ngeso lengqondo izinyathelo zokukhipha imininingwane ngefomethi ye-raster kusuka kunoma yiziphi izinkundla ezishiwo ngenhla. Enye yezinzuzo zayo ezinkulu ukuthi izithombe ezilandwe ngalolu hlelo lokusebenza zenziwe nge-georeferenced, ezisindisa isikhathi ekwakhiweni komkhiqizo. Ngokuhlukile kulokho okwenzeka ngezithombe zeGoogle Earth, zingagcinwa - zilandwe, kepha zidinga izinqubo ze-georeferencing ezizayo, ezihumusha isikhathi

Ukulandelana kwezinyathelo zokulanda izithombe

Ukukhetha okukhazimulayo kwendawo ezithakazelisayo

1. Isinyathelo sokuqala ukulanda ifayela eliqukethe isifaki se-SAS Planet, kulokhu kusetshenziswe inguqulo yakamuva ekhishwe ukuze isetshenziswe ngumphakathi ngoDisemba 2018. Ifayela lilandwa ngefomethi ye-.zip, futhi ukuze lisebenze, kufanele livule iziphu okuqukethwe ngokuphelele. Lapho usuqedile, indlela eya lapho iya khona iyavuleka bese iSasplanet ephathekayo itholakala.
2. Lapho uqhuba uhlelo, umbono omkhulu wesicelo uvula. wamathuluzi eziningana (green), kanye main isicelo imenyu (umbala obomvu), umbono main (orange), i-zoom buka (ophuzi), isimo ngokuphathelene (purple), ibha waphawula wombuso nezixhumanisi (umbala we-fuchsia).
3. Ukuze uqalise search, uma wazi ukuthi yini edingekayo endaweni indlela kumephu umbono eyinhloko esikhathazeka ngayo, uze ufike endaweni oyifunayo kwelinye wamathuluzi Imininingwane umthombo raster ikhethwa kulokhu-Google .
4. Uma ufuna ukushintsha umthombo wokwaziswa, nje kuchofoziwe lapho igama isizinda wabonisa, kukhona abakhethwe: I-Google, Yandex, Nokia, Kosmsnimki, Navteq, Genplan eMoscow, GeoHub, i-Bing, Geoportal, Yahoo! , amanye amamephu, umlando, ezokuvakasha, amabalazwe omkhumbi, Isikhala, amamephu wendawo, i-OSM, i-ESRI, noma i-Google Earth.

5. Ngemuva kokhetho, ukukhethwa kwendawo edingekayo kwenziwa. Kuye ngokuthi i-raster ibhekwa kanjani, iseva ikhethwe, isibonelo isithombe se-Google esisetshenzisiwe, ngoba sasingekho uhlobo lwefu elikhona endaweni yesehlakalo.

5. Khona-ke, inkinobho ivuliwe Shift, nalokhu indawo yokutadisha izokhethwa nge-cursor. Vele uchofoze ekhoneni futhi uhudule endaweni oyifunayo, ukuchofoza kokugcina kwenziwa, futhi iwindi livuleka, lapho kufanele sibeke khona imingcele yokukhiqiza yesithombe esikhethiwe.

7. Ewindini, amathebhu amaningana abonakala, kokuqala kwawo Landa, izinga lokusondeza liyakhethwa. Izinga lokusondeza lisukela ku-1 liye ku-24 - isinqumo esiphezulu. Lapho isithombe sikhethiwe, kubha yokusondeza, izinga liyakhonjiswa, noma kunjalo, kuleli windi lingashintshwa. Iphinde ikhombise iseva lapho umkhiqizo uzokhishwa khona.

8. Kwithebhu elandelayo, imingcele yokukhipha ifakwa. Ngokuqondile ukuze i-raster igcinwe ngolwazi lwesithenjwa sendawo. Esikhathini (1) ibhokisi, ifomethi isithombe wabonisa ebhokisini (2) okukhipha endleleni, ibhokisi (3) iseva akhethiwe ku (4) ebhokisini uma ikhona ungqimba Imbondela, e ibhokisi (5) ukucaciswa kucacisiwe, bese kuthiwa iqembu libizwa Dala ifayela le-georeferencing (6), inketho elula kunazo zonke imakwe, kulokhu i .w,  ikhwalithi ishiywe ngokuzenzakalelayo ku-95%, futhi ekugcineni chofoza qala,
9. Isithombe ikhishelwe-JPG format, kodwa kungenziwa zithunyelwa ku takhiwo ezilandelayo: i-PNG, i-BMP, ECW (Ukuminyanisa Wavelet Ukuthuthukisa), JPEG2000, KMZ ngoba Garming (JPEG ukunqwabelanisa), RAW (olulodwa bitmap ingcaca), GeoTIFF.
10. Uma uhlola ifolda lapho isithombe silondoloziwe, amafayela we-4 angabonakala, ifayela le-raster .jpg, ifayela elisizayo, i-jpgw iyabonakala (lena ifayela lokubhekisela elidalwe ngaphambilini .w), kanye ne-.prj ehambisana nesithombe.

Ukubonisa okusheshayo ku-SIG

1. Ngemva kokuba nenqubo, ifayela livuliwe kunoma isiphi isofthiwe ye-GIS ukuze sikwazi ukuqinisekisa ukuthi isithombe sisendaweni edingekayo. Ukuze uqhubeke, kuhlelo lwe-ArcGIS Pro, izendlalelo zilayishwa ngesakhiwo sejamo, okubonisa indawo lapho isithombe esisha esithunyelwa khona kufanele sibekwe khona.
2. Uma uvula, ungabona ukuthi isithombe sifanelana ngokuphelele, nezakhi zendlela yokuma yombono oyinhloko, okungukuthi, nezidumbu zamanzi kwifomethi ye-vector. Isitsha esivela esithombeni sishintsha endaweni yendawo ye-polygon, ngakho-ke, kubhekwe njengento ekhonjisiwe ngokuphelele

Ukusetshenziswa kwe-hybrid

Uma ufuna ukukhipha idatha ye-raster namanye okuqukethwe, njengezitaladi nezindlela, futhi uwasebenzise kumadivayisi weselula endaweni yomsebenzisi, inqubo efanayo yokukhethwa kwendawo ezithakazelisayo yenziwa.

Umehluko wukuthi idatha yeseva ye-Bing manje izothathwa, kunguqulo yayo imigwaqo - imigwaqo, umbono omkhulu ubonisa izindawo ezithandayo kakhulu, kanye namagama emigwaqweni esemqoka. Uma uqhubeka nokubuka umbono oyinhloko, imininingwane ehlobene nendawo yokufunda ilayishwa.

Manje, uma i-raster yangaphambilini idinga ukuba nedatha yamamephu wamamephu kanye namasayithi ezithakazelo alayishiwe, kuphela hybrid - i-hybrid, evele imane idlulise idatha kusuka ezindaweni eziningi zokubhekisela, nesithombe se-raster.

1. Esikhathini sephaneli yamathuluzi, kunenkinobho enezingqimba ezingaphezulu, uma ungena lapho, zonke izizinda ezisemaphandleni ezingahle zivezwe nge-raster ziboniswa. Kusuka ku-Google, i-OSM - Vula i-Maps Street, i-Yandex, i-Rosreestr, i-Hybrid Yahoo, i-Hibrid Wikimapia, i-Navteq.
2. Khona-ke, ukuze uthole i-raster base, i-Bing Maps - Iseva yeSatellite isetshenziswa, bese ingeniswa kwimenyu hybrid, futhi usebenze abaningi njengoba kudingeka, - lokhu ukucacisa, yikuphi hybrid unolwazi oluthe xaxa, ngoba isibonelo sikhethiwe: i-Google, OSM, Wikimapia, ne-ArcGIS hybrid, umbono we-raster enezigaba ezivelele uboniswa ngezansi.

3. Ukulondoloza isithombe, nedatha hybrid, ukubuka kukhethwe njengamacala angaphambilini, kodwa manje, uma isikrini semingcele yesithombe siboniswa, okulandelayo kukhethiwe: kuthebhu ukugxuma,  ifomethi yokukhipha, indlela yokukhipha, i-raster base (Bing) ibekwa, futhi Isendlalelo sokuqhafaza  - i-Google Hybrid ikhethiwe - kanye nefayela lokubheka indawo .w.
4. Ngemuva kokuthi inqubo iqhutshwa, isithombe sivuliwe ku-SIG noma isofthiwe yezintandokazi zakho, futhi kuqinisekisiwe ukuthi isithombe esinemininingwane ephezulu ye-Google Hybrid empeleni sithunyelwa. Amalebula ezakhiwe endaweni ezithakazelisayo aboniswa, futhi uma ukuma kufakwa, itholakala ngqo lapho umzimba wamanzi kufanele uhambe khona.

Inqubo yalesi sihloko ingabonakala kwisiteshi se-Youtube se-Geofumadas

Consideraciones finales

Njengoba kungaqinisekiswa, ukusetshenziswa kwethuluzi kulula, akudingi imizamo emikhulu yokuqonda amandla enqubo ngayinye namathuluzi ayiqambayo. Ngakho-ke, ukusetshenziswa kwayo kunconywa kakhulu.

Ngokungafani nezinye izinyathelo kulo msebenzi wokulanda izithombe ezisekelwe geore, njenge-case of I-Stitchmap, ukuziphendukela kwemvelo i-SASPlanet enakho ukuhlengwa, okuhlale kufaka amathuluzi nokusebenza kokunye kokuvuselelwa kwayo, kanye nokufinyelela kuzinsizakalo eziningi ngokwengeziwe. Lo mbhalo wenziwe kusetshenziswa inguqulo yakamuva ezinzile, kusuka ngoDisemba 21, 2018, kepha-ke, sikunikeza lesi sixhumanisi, kusuka ekhasini elisemthethweni, eliqukethe indawo yokugcina yazo zonke izinhlobo ezikhishwe kusukela ngo-2009.

Siyakuhalalisela i-SASPlanet neminyaka yayo engu-10 yokuqhubeka.
