Install GDAL

An attempt to keep a 'working' repository of installing GDAL on Amazon Linux 2 and Windows with Python libraries.

GDAL and Python

There are two python wrappers for accessing GDAL C library functions.

1. django.contrib.gis the built in django wrapper for basic access to GDAL.

   • Only installs the Python bindings as django.contrib.gis.gdal
   • Requires GDAL libraries to be installed separately on the system
   • It is only a simple version of the full GDAL library

   GeoDjango provides a high-level Python interface for some of the capabilities of OGR, including the reading and coordinate transformation of vector spatial data and minimal support for GDAL’s features with respect to raster (image) data.

2. osgeo (installed as pip install gdal==3.1.4) installs the OSGeo wrapper AND GDAL libraries

   • Installs and builds BOTH Python bindings AND GDAL Libraries
   • GDAL Libraries are installed to the python env site-packages gdal directory
   • OSGeo will use these local library files
   • django.contrib.gis will NOT use these library files
