Online documentation for GDAL/OGR Python is sparse. Here I show some recommended ways of learning more about GDAL/OGR in Python.
Using Python interpreter
You can learn about GDAL and OGR from inside the Python interpreter.
Start python interpreter:
Import the modules:
from osgeo import gdal,ogr,osr
Learn about the modules using 'help' and 'dir' in Python. These built-in functions work for any type of object (module, class, functions etc):
help(ogr) # display help for the ogr module dir(ogr) # what's contained in ogr module? help(ogr.Geometry) # display help for ogr.Geometry class dir(ogr.Geometry) # show contents of an object, like functions on a class
gis.stackexchange.com is a Q&A site about GIS. Many people here know about GDAL and ORG, also about the Python bindings.
Some good questions I've found:
Transformation using OGR in Python
Will add more as I find them...
