Good for you.
"Repetitive tasks" is not really something that everyone has a finite list of, but rather ends up being pertinent to some of the problems you may be dealing with at any moment.
Also, there are many ways to skin a cat, so, List, feel free to flay my thoughts or better still to add to them - but I think that as a community let's take this opportunity to help someone get started, and to also learn as a collective.
A couple of thoughts:
So, to your (Charles's) query:
As a kick-off, you might find that far too often when you start a job/contract, you are given a pile of orthos, and told to "use these" - only to later find out that (for example) they do not cover your area of interest.
So a useful routine might be to create something that will visually show you the coverage of the orthos that may be in a folder.
The cynical may say "Just load them into QGIS", but I say: "I've just received a HD of 38526 orthos from NGI - I wonder which ones I don't have?" :-)
As a first exercise perhaps try this:
pick a pile of orthos that you know are on the same CRS, and write a python script that:
I suggest staying in one CRS so that you don't have the extra hassle of re-projecting your extents.
Hope this helps,
Yes, there are many other ways to achieve the goals of this example, but this method will allow one to learn how to dive out of Python into the OS to list a directory, link to external libraries, and output a text file for input to another system.
