[Qgis-user] Need help with learning Field Calculator.

[Priyank Shah]

Hello Everyone,

I'm a Wildlife Biologist willing to upskill myself, so I took a course on
Udemy - "Open source GIS and Remote sensing for conservation."

The course is amazing, has great resources and contents and just focuses on
the conservation aspects of GIS which is what I wanted to do.

The problem for me began when it introduced the Field Calculator, so the
thing is I'm more of a practical person by practising things I learn and
understand it better rather than someone just showing it or theoretical.

So, when I learned the course I stumbled on the calculator, to complete the
assignments and following the instructor was easy as it was just copy
paste, but my biggest problem is How do I learn to work the calculator by
my own like to follow the instructor it just copying him, but if i want to
progress in it and work on my own, I'm totally confused and blank on what
are the functions how to navigate, why only certain functions need to be
selected and not the other, even having the same name.

So, is there a better simpler way of doing this?

I really want to learn QGIS from its conservation point of view. Indeed I
liked doing it when I tried doing other things on my own, but this field
calculator got me a bit anxious.

If there are ways of learning some tips or tricks, I would really
appreciate your help guys!

Thanks so much.
