QGIS, isai iyo paUbuntu 18.10 uye shanda neruzivo rwe geospatial

Munyaya inotevera tichazotarisa QGIS. Ichi chi vhura sosi software package yekudhirowa ruzivo rwe geospatial. QGIS inozivikanwa kwazvo muchinjika-chikuva geographic ruzivo system. Tichaiwana ichiwanika yeGnu / Linux, Mac uye Windows. Mune ino posvo tichaona kuti sei gadza QGIS 3 pane Ubuntu 18.10.

QGIS (yaimbonziwo Quantum GIS) yaive yemamwe mapurojekiti masere ekutanga eOSGeo Foundation. Iyi software ichatibvumidza kubata raster uye vector mafomati kuburikidza neGDAL uye OGR maraibhurari, pamwe nemadhata.

Hunhu hwakawanda hweQGIS

Zvimwe zvehunhu hwayo ndeizvi:

• Uchatipa vector faira rinobata Shapefile, ArcInfo zvivharo, Mapinfo, GRASS GIS, DXF, DWG, nezvimwe.
• Tichava nerutsigiro rwehuwandu hwakawanda hwemhando dze raster mafaera (GRASS GIS, GeoTIFF, TIFF, JPG, nezvimwewo)
• Imwe yemabhenefiti ayo makuru mukana we shandisa Quantum GIS seGUI yeiyo SIG GRASS, uchishandisa ese masimba ekuongorora eiyo yekupedzisira munzvimbo ine hushamwari yebasa.
• QGIS inogadzirwa muC ++, uchishandisa iyo Qt raibhurari yeyako interface mushandisi girafu.
• Imwe yemasimba makuru eQGIS ndeyekuti inoshanda pane akasiyana masisitimu anoshanda senge: GNU / Linux, BSD, Unix, Mac OSX, Windows uye Android (muchikamu chekuyedza). Izvo zvinoshanda zvakafanana mune ese iwo.
• QGIS ine plugin yezvivakwa. Mushandisi anogona wedzera kuwanda kwekushanda nyowani nekunyora ako wega plugins. Aya plugins anogona kunyorwa muC ++ kana Python.
• QGIS 3.0 shandisa iyo Python vhezheni 3.X. Inopa vanogadzira nehukama kune mienzaniso uye nongedzo yePlugin Builder sePython turu yekuvandudza.

Tinogona ziva zvakawanda nezve all inoratidza chirongwa ichi papeji rake rewebhu.

Isa QGIS pane Ubuntu 18.10

Tinogona kuisa iyi software nenzira dzakasiyana pane yedu Ubuntu 18.10 system:

Isa kuburikidza neAPT

Kuisa QGIS kuburikidza neAPT package maneja, isu tinongofanirwa kuvhura terminal (Ctrl + Alt + T) uye tinyore mairi:

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

Iyi sarudzo ichaisa vhezheni 2.18 yechirongwa pane yedu system. Kana tichida yazvino vhezheni vhezheni, enda kune inotevera poindi.

Isa kuburikidza neyako repository

Nesarudzo iyi isu tichaisa yazvino vhezheni, kunyanya nhasi, 3.4. Tinogona kuwedzera zvakananga kune iyo faira /etc/apt/sources.list inoenderana inochengeterwa. Tichagadzirisa iyi faira nemirairo inotevera:

sudo vim /etc/apt/sources.list

Isu tinongoda kuwedzera imwezve tambo.

Sezvo isu tiri kushandisa Ubuntu 18.10 Cosmic Cutlefish yemuenzaniso uyu, isu tichafanirwa kuwedzera chaiyo repository yeUbuntu 18.10 kubva kuQGIS 3. Iyo Ubuntu Cosmic Cutlefish codename iri nzvimbo. Kune izvi isu tichafanirwa kuwedzera unotevera mutsara kumusoro kana pasi pefaira /etc/apt/sources.list:

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

Mushure meizvi, isu tinoponesa nekuvhara iyo faira. Zvino isu tichafanira kuendesa GPG kiyi kubva kuQGIS 3 nemirairo inotevera:

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

Iyo GPG kiyi inofanirwa kuwedzerwa kune yako Ubuntu 18.10 muchina. Zvino unogona tarisa kana kiyi yeGPG yakaunzwa nenzira kwayo nemirairo inotevera:

gpg --fingerprint CAEB3DC3BDF7FB45

Zvino tinofanira wedzera QGIS 3 GPG kiyi kune apt package maneja. Zvikasadaro, iwe haugone kumutsiridza cache uye kurodha pasi nekuisa QGIS 3. Kuti tiite chiito ichi isu tichaita mune chinongedzo (Ctrl + Alt + T)

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

Panguva ino, isu tinofanirwa gadziridza iyo Ubuntu 18.10 apt package repository cache:

sudo apt update

Zvino tinogona gadza QGIS 3:

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

Iyo QGIS 3 yekurodha uye yekumisikidza maitiro inofanira kutanga. Izvi zvinogona kutora chinguva.

Kutanga QGIS

Iye zvino tinogona kuenda kuGNOME 3 Desktop Nzvimbo Yekuita uye kutsvaga qgis. Isu tinofanirwa kuwana iyo QGIS Desktop logo sezvakaratidzwa mune inotevera skrini. Tichadzvanya pairi kuvhura chirongwa ichi.

Kana iwe wakamboshandisa QGIS kare uye uine zvigadziriso zveiyo yapfuura vhezheni, uchakwanisa kusarudza "Pinza kumisikidza kubva kuQGIS 2". Kana iwe uri mutsva kune iyi software, sarudza "Ndinoda kutanga kwakachena”Muhwindo iro richaratidzwa usati waisa purogiramu.

Kana chirongwa ichi chatanga, iwe unofanirwa kuona iyo QGIS 3 kurodha hwindo sezvakaratidzwa mune inotevera skrini.

Kamwe kurodha zvinhu zvese zvinodiwa kwapera, isu tinofanirwa kuona hwindo hombe rechirongwa.

Iye zvino tinogona kutanga kugadzira ruzivo rwe geospatial. Kuti uwane rumwe ruzivo nezve mashandisiro echirongwa ichi, tinogona kureva iyo zvinyorwa zvepamutemo yepurojekiti.
