Fayilo yokhala ndi fayilo ya fayilo ya HGT ndi fayilo ya data ya Shuttle Radar Topography Mission (SRTM).
Mafayili a HGT ali ndi zithunzi zapamwamba zojambulajambula, zomwe ndi zithunzi za 3D zapamwamba - kawirikawiri dziko lapansi, lomwe linapezedwa pa Shuttle Radar Topography Mission (SRTM) ndi NASA ndi National Geospatial-Intelligence Agency (NGA).
Kugwiritsidwa ntchito pano, "HGT" ndi chidule cha "kutalika." Fayilo ya .HGT nthawi zambiri imatchulidwa ndi longitude ndi chikhalidwe chomwe fanolo limatanthawuza, muyeso imodzi. Mwachitsanzo, fayilo N33W177.hgt ingasonyeze kuti imaphatikizapo deta ya kutalika 33 mpaka 34 kumpoto ndi kutalika kwa 177 mpaka 178 Kumadzulo.
Dziwani: mafayilo a SRTM Data alibe chochita ndi mafayilo a SRT .
Mmene Mungatsegule Faili la HGT
Maofesi a HGT akhoza kutsegulidwa ndi VTBuilder, ArcGIS Pro, ndi Safe Software's FME Desktop. DG Terrain Viewer amagwira ntchito, komanso, kwa Windows ndi Linux. Mukhozanso kutumiza fayilo ya HGT ku Blender ndi blender-osm addon.
Zindikirani: Ngati mukugwiritsa ntchito VTBuilder kuti mutsegule fayilo yanu ya HGT, siinayambe mkati mwa chinthu chokhazikika cha polojekiti ya Open Project . M'malo mwake, uyenera kulowetsa fayilo pulogalamuyo kudzera pa Layer> Import Data> Elevation menu.
Onani tsamba lotchedwa Shuttle Radar Topography Mission homepage, yokonzedwa ndi Laboratory ya NASA Jet Propulsion Laboratory, chifukwa cha maziko onse a SRTM deta, yomwe imabwera mu mtundu wa HGT. Deta yokha imatha kumasulidwa kuchokera patsamba la SRTM loperekedwa ndi US Geological Survey.
Palinso mwachidule, apa, a SRTM ndi deta yopangidwa. Webusaiti ya USGS imakhalanso ndi zambiri, apa , mu PDF .
Langizo: Ngati muli ndi fayilo ya HGT yomwe simukudziwa kuti ndi fayilo ya SRTM, kapena simagwira ntchito ndi mapulogalamu onse omwe mumaphunzira pamwambapa, zikhoza kukhala kuti fayilo yanu ya HGT ndi yosiyana kwambiri . Ngati ndi choncho, gwiritsani ntchito mndandanda wa malemba kuti mutsegule fayilo. Nthawi zina , pamakhala fayilo yomwe imatha kukuthandizani kuti mumvetsetse pulogalamu yomwe inagwiritsidwa ntchito popanga fayilo, yomwe ikuyenera kukutsogolerani ku chidziwitso chowonjezeka.
Mukapeza kuti pulogalamu yanu pamakompyuta yanu imayesera kutsegula fayilo ya HGT, koma ndizolakwika kapena ngati mukufuna kukhala ndi ndondomeko yowonjezera maofesi awa, onani momwe tingasinthire ndondomeko yodalirika ya phunziro lapadera lazowonjezera mafayilo Thandizani kusintha makonzedwe amenewo.
Momwe mungasinthire fayilo ya HGT
VTBuilder akhoza kutumiza fayilo ya HGT ku fayilo ya Binary Terrain (.BT). Kuti muchite izi, yambani kuitanitsa fayilo ya HGT ( Layer> Import Data> Elevation ) ndikuisunga pogwiritsa ntchito Gawo> Sungani Zomwe Muli ....
VTBuilder imathandizanso kutumizira fayilo ya HGT ku PNG , TIFF , ndi zina zambiri, zomwe sizowoneka, mafano ndi ma data.
Mu ArcGIS Pro, ndi fayilo ya HGT yotseguka pulogalamuyi, muyenera kupita ku Export> Raster to Different Format kuti muzisunga fayilo HGT pansi latsopano.
Mapulogalamu ena pamwambapa angasinthe mafayilo a HGT, nawonso. Izi ndizochitika kudzera mu njira yotumizira kunja kapena Masewera monga Mapulogalamu .
