How To Install GDAL/OGR Packages on Ubuntu¶
GDAL is a translator library for raster and vector geospatial data formats.
OGR Simple Features Library is a C++ open source library (and commandline tools) providing read (and sometimes write) access to a variety of vector file formats including ESRI Shapefiles, S-57, SDTS, PostGIS, Oracle Spatial, and Mapinfo mid/mif and TAB formats.
OGR is a part of the GDAL library.
This article describes a process you can follow to install GDAL/OGR on Ubuntu.
Before You Begin: Python 3.6¶
If you are installing the GDAL/OGR packages into a virtual environment based on Python 3.6, you may need to install the python3.6-dev package.
sudo apt-get install python3.6-dev
For more information about creating virtual environments on Ubuntu 16.04 LTS, see A Note About Python 3.6 and Ubuntu 16.04 LTS.
Much of this section is taken from a really helpful blog post by Sara Safavi. Follow these steps to get GDAL/OGR installed.
To get the latest GDAL/OGR version, add the PPA to your sources, then install the gdal-bin package (this should automatically grab any necessary dependencies, including at least the relevant libgdal version).
sudo add-apt-repository ppa:ubuntugis/ppa && sudo apt-get update
Once you add the repository, go ahead and update your source packages.
sudo apt-get update
Now you should be able to install the GDAL/OGR package.
sudo apt-get install gdal-bin
To verify the installation, you can run
Install GDAL for Python¶
Before installing the GDAL Python libraries, you’ll need to install the GDAL development libraries.
sudo apt-get install libgdal-dev
You’ll also need to
export a couple of environment variables for the compiler.
export CPLUS_INCLUDE_PATH=/usr/include/gdal export C_INCLUDE_PATH=/usr/include/gdal
Now you can use
pip to install the Python GDAL bindings.
pip install GDAL
Putting It All Together¶
If you want to run the whole process at once, we’ve collected all the commands above in the script below.
#!/usr/bin/env bash sudo add-apt-repository ppa:ubuntugis/ppa && sudo apt-get update sudo apt-get update sudo apt-get install gdal-bin sudo apt-get install libgdal-dev export CPLUS_INCLUDE_PATH=/usr/include/gdal export C_INCLUDE_PATH=/usr/include/gdal pip install GDAL
Try It Out¶
Now that GDAL/OGR is installed, and you can program against it in Python, why not try it out? The code block below is a sample from the Python OGR/GDAL Cookbook that gets all the layers in an Esri file geodatabase.
# standard imports import sys # import OGR from osgeo import ogr # use OGR specific exceptions ogr.UseExceptions() # get the driver driver = ogr.GetDriverByName("OpenFileGDB") # opening the FileGDB try: gdb = driver.Open(gdb_path, 0) except Exception, e: print e sys.exit() # list to store layers'names featsClassList =  # parsing layers by index for featsClass_idx in range(gdb.GetLayerCount()): featsClass = gdb.GetLayerByIndex(featsClass_idx) featsClassList.append(featsClass.GetName()) # sorting featsClassList.sort() # printing for featsClass in featsClassList: print featsClass # clean close del gdb
