QGIS, yifake kwi-Ubuntu 18.10 kwaye usebenze ngolwazi lwe-geospatial

Kwinqaku elilandelayo siza kujonga i-QGIS. Oku yi Isoftware evulekileyo yokuzoba Ulwazi lwe-geospatial. I-QGIS yinkqubo ethandwayo yeqonga lendawo. Siza kuyifumana ifumaneka kwi-Gnu / Linux, Mac kunye neWindows. Kule posi siza kubona ukuba njani Faka i-QGIS 3 kwi-Ubuntu 18.10.

I-QGIS (eyayibizwa ngokuba yi-Quantum GIS) yenye yeeprojekthi zokuqala ze-OSGeo Foundation. Le software iyakusivumela ukuba siphathe iifomathi ze-raster kunye nevector ngokusebenzisa iilayibrari ze-GDAL kunye ne-OGR, kunye noovimba beenkcukacha.

Iimpawu ngokubanzi zeQGIS

Ezinye zeempawu zayo zezi:

• Ngaba uya kusinika Ukusingathwa kwefayile Ifayile yesakhelo, iiArcInfo, iMapinfo, IGREAS GIS, iDXF, iDWG, njl.
• Siza kuba nenkxaso kwinani elibalulekileyo leentlobo ze iifayile zeRaster (IGRIS GIS, GeoTIFF, TIFF, JPG, njl.)
• Enye yeenzuzo zayo ezinkulu linokwenzeka Sebenzisa i-Quantum GIS njenge-GUI ye-SIG GRASS, kusetyenziswa onke amandla ohlalutyo lwamva kwimeko yokusebenza enobuhlobo.
• QGIS iphuhliswa kwi-C ++, usebenzisa Qt ilayibrari ujongano lwakho igrafu yomsebenzisi.
• Olunye lwamandla amakhulu e-QGIS yile isebenza kwiinkqubo ezahlukeneyo zokusebenza njenge: GNU / Linux, BSD, Unix, Mac OSX, Windows kunye ne-Android (kwisigaba sokulinga). Isebenza ngokufanayo kuzo zonke.
• I-QGIS inesiseko se-plugin. Umsebenzisi unako yongeza uninzi lomsebenzi omtsha ngokubhala iiplagi zakho. Ezi plugins zinokubhalwa kwi-C ++ okanye iPython.
• QGIS 3.0 Sebenzisa i Inguqulelo yePython 3.X. Inika ababhekisi phambili ngamakhonkco kwimizekelo kunye nezikhokelo zoMakhi wePlagi njengesixhobo sophuhliso sePython.

Sinako wazi ngakumbi malunga las ibonisa le projekthi kwiphepha lakhe lewebhu.

Faka i-QGIS kwi-Ubuntu 18.10

Singayifaka le software ngeendlela ezahlukeneyo kwinkqubo yethu Ubuntu 18.10:

Faka nge-APT

Ukufakela i-QGIS ngokusebenzisa umphathi wephakheji ye-APT, kufuneka sivule i-terminal (Ctrl + Alt + T) kwaye sibhale kuyo:

sudo apt install qgis python-qgis qgis-plugin-grass

Olu khetho Ndiza kufaka inguqulelo 2.18 yenkqubo kwinkqubo yethu. Ukuba sifuna uhlobo lwamva nje, yiya kwindawo elandelayo.

Faka ngokugcina

Ngale ndlela siza kufaka uhlobo lwamva nje, ngakumbi namhlanje, 3.4. Singongeza ngokuthe ngqo kwifayile /etc/apt/sources.list indawo ehambelana nayo. Siza kuhlela le fayile ngalo myalelo ulandelayo:

sudo vim /etc/apt/sources.list

Siya kufuna ukongeza umgca omnye kuphela.

Njengoko sisebenzisa Ubuntu 18.10 Cosmic Cutlefish kulo mzekelo, kuya kufuneka songeze indawo ethile Ubuntu 18.10 kwiQGIS 3. I-Ubuntu Cosmic Cutlefish codename yile indalo. Ngale nto kuya kufuneka songeze lo mgca ulandelayo phezulu okanye ezantsi kwifayile /etc/apt/sources.list:

deb https://qgis.org/ubuntu cosmic main

Emva koku, siyagcina kwaye sivale ifayile. Ngoku kuya kufuneka ukungenisa isitshixo se-GPG kwi-QGIS 3 ngalo myalelo ulandelayo:

wget -O - https://qgis.org/downloads/qgis-2017.gpg.key | gpg --import

Isitshixo se-GPG kufuneka songezwe kumatshini wakho we-Ubuntu 18.10. Ngoku unako jonga ukuba isitshixo se-GPG singeniswe ngokuchanekileyo ngalo myalelo ulandelayo:

gpg --fingerprint CAEB3DC3BDF7FB45

Ngoku kufuneka Yongeza iqhosha le-QGIS 3 GPG kumphathi wephakheji efanelekileyo. Ngaphandle koko, awuyi kuba nakho ukuhlaziya i-cache kwaye ukhuphele kwaye ufake i-QGIS 3. Ukwenza le nyathelo siya kuyenza kwisiphelo sendlela (Ctrl + Alt + T):

gpg --export --armor CAEB3DC3BDF7FB45 | sudo apt-key add -

Okwangoku, kufuneka Hlaziya i-Ubuntu 18.10 yephakheji yokugcina indawo yokugcina izinto:

sudo apt update

Ngoku sinako faka iQGIS 3:

sudo apt install qgis python-qgis qgis-plugin-grass

Inkqubo yokukhuphela kunye ne-QGIS 3 kufuneka iqale. Oku kungathatha ixesha.

QGIS Qalisa

Ngoku singaya kwi-GNOME 3 Imisebenzi yeDesktop yeNdalo kunye nokukhangela i-qgis. Kuya kufuneka sikwazi ukufumana ilogo ye-QGIS yeDesktop njengoko kubonisiwe kumfanekiso olandelayo. Siza kucofa kuyo ukuze sazise inkqubo.

Ukuba ubukhe wasebenzisa i-QGIS ngaphambili kwaye uneenkqubo zangaphambili, uyakwazi ukukhetha "Ngenisa ubumbeko olusuka kwiQGIS 2”. Ukuba umtsha kule software, khetha "Ndifuna isiqalo esicocekileyo”Kwifestile ezakuboniswa ngaphambi kokulayisha inkqubo.

Xa inkqubo isungula, kuya kufuneka ubone i-QGIS 3 yokulayisha iwindow njengoko kubonisiwe kule skrini ilandelayo.

Nje ukuba ukulayishwa kwayo yonke into eyimfuneko kugqityiwe, kuya kufuneka sibone iwindow ephambili yenkqubo.

Ngoku sinokuqala ukudala ulwazi lwe-geospatial. Ngolwazi oluthe kratya malunga nendlela yokusebenzisa le nkqubo, singabhekisa kwi amaxwebhu asemthethweni yeprojekthi.
