ʻO kahi pūnaewele me ka hōʻailona HGT e hoʻopiliʻia anaʻo kahi pūnaeweleʻIkepiliʻo Topography Mission (SRTM).
HGT nā waihona i nā hiʻohiʻona hohola kiʻi,ʻo ia nā kiʻiʻekolu o kaʻili - ma keʻano he honua, i loaʻa i ka Mānā Topography Mission (SRTM) na NASA a me ka National Geospatial-Intelligence Agency (NGA).
Hoʻohanaʻia maʻaneʻi,ʻo "HGT" kahi kahakaha wale no "kiʻekiʻe." Kāheaʻia ka waihona .GGT me ka longitude a me ka latitude e pili ana i ke kiʻi, i loko o ke kēkelē. Eia kekahi laʻana,ʻo ka file N33W177.hgt e hōʻike i loko o kaʻikepili no nā latitudes 33 a 34 Mākau a me nā lōʻihi 177 a hiki i 178 Komohana.
Nānā: ʻAʻohe mea i hanaʻia me nā kōnae SRT .
Pehea e wehe ai i kahi Kōnae HGT
Hiki i nā puka HGT ke weheʻia me ka VTBuilder, ArcGIS Pro, a me ka FME Desktop Pūnaewele. Kūkuluʻo DG Terrain Viewer, no ka Windows a me Linux. Hiki iāʻoe ke hoʻokomo i kahi pūnaewele HGT i Blender me ka'ōmole blender-osm.
Nānā: Inā hoʻohanaʻoe i ka VTBuilder e wehe i kāu waihona HGT,ʻaʻole i hanaʻia ma loko o ka papahana papahana Papa Hana Kūwaho. Ma kahi kūpono, ponoʻoe e hoʻokomo i ka faila i loko o ka papahana ma o ka Layer> Import Data> Haʻuna koho.
Eʻike i ka homepage Mīkiniʻo Radar Topography Mission, i mālamaʻia e ka NASA Jet Propulsion Laboratory, no nā mea nui i nāʻike SRTM, hiki i ka hōʻailona HGT. Hiki ke kiʻiʻia nāʻikepili mai ka palapala SRTM i mālamaʻia e ka US Geological Survey.
Aia kekahi nānā nui loa, maʻaneʻi, o ka SRTM a me nāʻike i hanaʻia. Loaʻa i ka pūnaewele USGS kekahi mauʻike hou aku, maʻaneʻi , ma ka PDF .
Kōkuhi: Inā loaʻa iāʻoe kahi waihona HGT āu eʻike nei,ʻaʻole ia he waihonaʻIkepili SRTM, aiʻoleʻole e hanaʻia me kekahi o nā polokalamu āu i heluhelu ai ma luna nei, hiki nō paha kāu kiko'ī HGT maʻamau i loko o kahiʻanoʻokoʻa loa . Inā pēlā, e hoʻohana i ka hoʻoponopono kikokikona e wehe i ka faile. I kekahi manawa , aia kahi kikokikona i loko o ka waihona e hiki ke kōkua iāʻoe e hoʻomaopopo i ka'ōnaehana i hoʻohanaʻia no ka kūkuluʻana i ka leka, a he mea ia e kuhikuhi iāʻoe i kaʻike hou aku ma ka hōpili.
Ināʻikeʻoe he polokalamu ma kāu kamepiula e ho'āʻo i ka weheʻana i ka pūnaewele HGT, akā,ʻo ia ke noi ponoʻole a inā makemakeʻoe e hoʻolālā i kahi papahana'ē aʻe i hoʻomaka i kēia mau kōnae, eʻike i kā mākou Pehea e Hoʻololi ai i ka Polokalamu Pahuho no kahi Kūlana Kūlana Kōnae Kūikawā. kōkua e hoʻololi i kēlā mau kikowaena.
Pehea e hoʻololi ai i kahi Kōnae HGT
Hiki i ka VTBuilder ke hoʻokuʻu aku i kahi waihona HGT i kahi faila Binary (.BT). No ka hanaʻana i kēia, e hoʻokomo mua i ka waihona HGT ( Layer> Import Data> Hiki ) a laila e mālama iā ia me ka Layer> Save Layer As ... option.
Mālama ka VTBuilder i ka hoʻokuʻuʻana aku i kahi waihona HGT i PNG , TIFF , a me kekahi mau mea likeʻole, aʻaʻole like keʻano maʻamau, kiʻi a me nā hōpili palapala.
Ma ArcGIS Pro, me ka waihona HGT i wehe muaʻia i loko o ka papahana, pono iāʻoe ke hele i Export> Hōʻano'ē i Ka Hoʻohālikeʻana no ka mālamaʻana i ka pūnaewele HGT ma lalo o kahi hōʻano hou.
Hiki i nā papahana'ē aʻe ma luna nei ke hoʻololi i nā pūnaewele HGT. Hanaʻia kēia ma waena o kahi koho Export a iʻole kahi Palekanaʻo ka menu.
