Installation & Setup¶
Windows Users¶
If you're running Windows, use the OSGEO4W Installer to download & installa variety of free & open source geospatial tools, including GDAL & QGIS.
Visit http://trac.osgeo.org/osgeo4w, andfollow the Quick Start for OSGeo4W Users steps:
During the setup process, make sure to select both the "GDAL" package and"QGIS" to be installed.
TIP: if you run into issues after the initial run of the installer, re-runthe OSGEO4W installer & repeat steps 2-5 above. It's possible that somedependencies will not be installed on the first run.
Once installation is complete, you'll use the OSGeo4W Shell to access commandline utilities like GDAL. This shell is automatically installed aftercompleting the above.
Mac Users¶
If you're running Mac OS X,KyngChaos is a good way to getinstallable packages for both QGIS & GDAL.
To install QGIS, download the QGIS version listed under Current fromhttp://www.kyngchaos.com/software/qgis:
Here, the "Current" version available for download is QGIS 2.18.13-1
To install, right-click the installer file and select Open. A securitywarning will pop up, but you can continue the installation safely (for moreinformation, see the 'Install Note' at the top of thispage).
Follow a similar process to install GDAL fromhttp://www.kyngchaos.com/software/frameworks.Under GDAL Complete, select the download for the GDAL version beginningwith "2".
Here, the 2.x version available for download is GDAL 2.1
Right-click the downloaded file & select Open to begin the installation.
After the installation is complete, there's one more step required to enableGDAL's command line tools. To finish setup, open your terminal and type thefollowing at the prompt:
echo 'export PATH=/Library/Frameworks/GDAL.framework/Programs:$PATH' >> ~/.bash_profile
Hit enter after that line, and type the following:
source ~/.bash_profile
After you hit enter again, setup is complete.
Linux Users¶
For most users, your Linux distribution's default repository is likely to havea relatively recent version of GDAL. Feel free to simple use that package, orread on for more specific information:
Ubuntu & Linux Mint Users
As of October 2017, Ubuntu's default (Universe) repositories have GDAL 1.11.To check what version of gdal is currently available to you, run the followingcommand:
sudo apt-cache policy gdal-binTo install that version, do:
sudo apt-get install gdal-binAlternatively, if you are running an LTS (12.04, 14.04, or 16.04) youcan use the ubuntugis-unstable PPA to install GDAL 2+. If you prefer thisoption, run the following instead:
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstablesudo apt-get updatesudo apt-get install gdal-binCentOS Users
In order to install GDAL, you'll need to use the EPEL repository. Follow theinstructions for your CentOS versionhere to do that.
For example: for CentOS7, assuming epel-release-7-10 is the relevant EPEL release, you would do:
su -c 'rpm -Uvh http://download.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-10.noarch.rpm'Once you've added the EPEL repository, run the following command:
sudo yum install gdalEveryone Else
You can also build GDAL yourself, by compiling from source. Detailedinstructions on this are available at http://trac.osgeo.org/gdal/wiki/BuildingOnUnix
All Users¶
Before going on, let's verify that the setup process completed successfully.
If QGIS has installed successfully, you should be able to find anewly-installed program, QGIS Desktop, on your system:
To confirm GDAL installation, open a terminal and type the following command:
ogrinfo
Windows users: remember, you'll use the OSGeo4W Shell here.
If all went well, you should get output similar to this:
Usage: ogrinfo [--help-general] [-ro] [-q] [-where restricted_where|@filename] [-spat xmin ymin xmax ymax] [-geomfield field] [-fid fid] [-sql statement|@filename] [-dialect sql_dialect] [-al] [-rl] [-so] [-fields={YES/NO}] [-geom={YES/NO/SUMMARY}] [-formats] [[-oo NAME=VALUE] ...] [-nomd] [-listmdd] [-mdd domain|`all`]* [-nocount] [-noextent] datasource_name [layer [layer ...]]FAILURE: No datasource specified.If, however, you get an error that says command not found, go back and reviewthe installation steps for your operating system.
