Ifayile enefayile yeHGT isandiso seShuttle Radar Topography Mission (SRTM) Ifayile yedatha.
Iifayile ze-HGT ziqukethe imodeli yokuphakama yedijithali, eyimifanekiso ye-3D yomhlaba-ngokuqhelekileyo iplanethi, efunyenwe ngexesha le-Shuttle Radar Topography Mission (SRTM) yi-NASA kunye ne-National Geospatial-Intelligence Agency (NGA).
Isetyenziswe apha, "i-HGT" imfutshane nje "yokuphakama." Ifayile yeHGT idla ngokuba ngumgama kunye nobubanzi obunomfanekiso, ngokukodwa. Ngokomzekelo, ifayile ye- N33W177.hgt iya kubonisa ukuba iquka idatha yeemigangatho 33 ukuya kuma-34 eNyakatho kunye nobude obude 177 ukuya ku-178 eNtshona.
Qaphela: iifayile ze-SRTM zedatha azibandakani namafayile e- SRT .
Indlela yokuvula ifayile yeHGT
Iifayile ze-HGT zingavulelwa nge-VTBuilder, i-ArcGIS Pro, kunye ne-Desktop ye-FME Desktop. I-DG Terrain Viewer isebenza, kwakhona, kwiWindows kunye ne-Linux. Ungaphinde ufake ifayile yeHGT kwi-Blender kunye ne-blender-osm addon.
Qaphela: Ukuba usebenzisa i-VTBuilder ukuvula ifayile yakho ye-HGT, akukwenziwanga kwinto yeMenyu yeProjekthi evulekileyo. Endaweni yoko, kufuneka ungenise ifayile kwiprogram nge Layer> Import Data> Imenyu yokunyuka .
Jonga i-homepage ye-Shuttle Radar Topography Mission, ebanjwe yi-NASA Jet Propulsion Laboratory, kuzo zonke iziseko kwi-SRTM idatha, ezayo kwifomathi ye-HGT. Idata ngokwayo ingalandwa kwikhasi le-SRTM eligcinwe yi-US Geological Survey.
Kukho umboniso omkhulu, apha, we-SRTM kunye nedatha eveliswe. Iwebhusayithi ye-USGS nayo inolwazi olungakumbi, apha , kwi- PDF .
Icebo: Ukuba unayo ifayile ye-HGT owaziyo akuyiyo ifayile ye-SRTM yedatha, okanye ayisebenzi naliphi na isofthiwe oyifunayo malunga nelapha ngasentla, ingaba ifayile yakho ethile ye-HGT ngokwenene ifomathi ehlukileyo ngokupheleleyo . Ukuba kunjalo, sebenzisa umhleli wombhalo ukuvula ifayile. Ngamanye amaxesha , kukho umbhalo ochanekileyo ngaphakathi kwefayili engakunceda uqonde ukuba yeyiphi inkqubo eyasetyenziswa ekwakheni ifayile, ekufuneka ikukhokele kwiinkcukacha ezingaphezulu kwifomathi.
Ukuba ufumanisa ukuba inkqubo kwikhompyutheni iyazama ukuvula ifayile yeHGT, kodwa yinto engafanelekanga okanye ukuba unokuba nelinye inkqubo efakiwe evule ezi fayile, khangela indlela yokutshintsha iNkqubo eZimiselweyo yokufundisa iFayile eyiNgcaciso yeFayile . kunceda ukutshintsha ezo zicwangciso.
Indlela yokuguqula iFayile yeHGT
I-VTBuilder inokuthumela iFayile yeHGT kwifayile yeBinary Terrain (BT). Ukwenza oku, kuqala ukungenisa ifayile ye-HGT ( Umthamo> Ukungenisa iDatha> Ukuphakama ) uze uyigcine usebenzisa iSakhiwo> Gcina i Layer njenge ... inketho.
I-VTBuilder iphinde isekele ukuthumela ifayile ye-HGT kwi- PNG , TIFF , kunye nenani lezinye izinto eziqhelekileyo, ezingafaniyo, imifanekiso kunye nedatha.
Kwi-ArcGIS Pro, kunye nefayile yeHGT evulekileyo kwiprogram, kufuneka ukwazi ukuya kwi- Export> I-Raster ukuya kwiFomathi eyahlukileyo ukugcina ifayile ye-HGT phantsi kwefomathi entsha.
Ezinye iinkqubo ezingentla ziyakwazi ukuguqula iifayile ze-HGT, nazo. Oku kuya kwenziwa ngokukhethwa kwe- Export okanye kwi- Save njenge menu.
