For polished map creation and interactive visualization, a desktop GIS software like QGIS may be a better, more fully-featured choice.That said, GDAL does have some standard processing scripts (for example pan-sharpening) and rasterio provides a plugin interface for workflows.Both libraries are critical for input/output operations, but you’ll draw on other libraries for computation (e.g.If you are working in a Python environment (ipython, scripts, jupyter lab).Maybe always?! Rasterio also has a set of command line tools.When should you use rasterio instead of GDAL? Note that GDAL also has auto-generated Python bindings, but we recommend using rasterio instead!.If you are comfortable with the terminal, GDAL’s command line utilities are very useful for scripting.Both GDAL and rasterio are constantly being updated and improved: As of writing this tutorial (July 2018), GDAL is at version 2.3.1 and rasterio is at version 1.0.2. One such python library developed and supported by Mapbox, rasterio, builds on top of GDAL’s many features, but provides a more pythonic interface and supports many of the features and formats that GDAL supports. There are a variety of geospatial libraries available on the python package index, and almost all of them depend GDAL is a powerful and mature library for reading, writing and warping raster datasets, written in C++ with bindings to other languages. Perform numerical operations on pixel values. Understand the basic components of a raster dataset and how to access them from a python program.
