Question:
Can anyone kindly suggest me a complete tutorial on Python for geospatial science?

My answer:
Hmmm.
Have you learnt basic python programming?

Also, you need to be familiar with the numpy, pandas, matplotlib and seaborn libraries.

Many platforms offer Python and data science courses but there are two that I find exceptional:
1. ustacky.com
2. jovian.ai/learn

That is to say, you should have taken at least a course in data science.

In fact, if you go as far as learning machine learning and deep learning it will assist you.

Many of tools used in geospatial science are built on data science tools. Although, some tools are completely unique to geospatial science.

If you have not taken any data science course, I don't think it's possible for you to cope in geospatial science.

That cleared, let me now answer your question.

1. You'll need to learn the following python libraries: Geopandas, PySal, Rasterio, rsgislib, scikit-gstat.

2. A good starting point is this open learning material by Professor Dani Arribas-Bell of the University of Liverpool.

Finally, this material should help you.

Good luck.

p.s: geospatial science is also spatial data science.
