Reviving the geotiff crate on top of image-tiff about geotiff

[weiji14]

Ok, started some general maintenance tasks like setting up CI (#8), bumping to Rust edition 2021 (#9) and fixing some compilation warnings (#10).

@dominikbucher or @frewsxcv, could you review some of those PRs (especially #8) if you have time? Or I could ask someone on the GeoRust Discord about getting write permissions to the repo.

Hi @weiji14! Awesome, and thanks a lot for kicking this off! Yeah, sure, I'll try my best to give you (hopefully valuable 😬) feedback on the PRs. And maybe I can carve off some time to work on it a bit as well, if there's interest. Of course also happy to have maintainers and contributors to the repo - I created it quite a while ago, but quickly had all the functionality I needed at the time, after which I stopped working on it.

I'll merge your PRs and change master to main (as per your github action workflow; just mentioning it to avoid confusion).

Thanks @dominikbucher! There's definitely wider interest on improving georust/geotiff (see discussion at busstoptaktik/geodesy#86), and I'm happy to contribute to refactoring parts of this repo to use the tiff crate, alongside @pka or any others who are interested.

but quickly had all the functionality I needed at the time, after which I stopped working on it.

Could you elaborate on this a little bit? I'm guessing that the main feature is the TIFF::get_value_at method, but was there any other functions you are relying on? I'm thinking of renaming the main struct from TIFF to GeoTIFF, so can't guarantee full backward compatibility, but will try to ensure there's an equivalent function somehow as we work towards a v0.1.0 release.

[dominikbucher]

No, absolutely, feel free to change things - as it was never on crates.io I doubt many people will be bothered by broken backward compatibility. I used it personally in a project together with a student, in the larger context of routing for electric vehicles (https://github.com/dominikbucher/e-route), but directly linked to the local project. I think it was simply getting the altitude of points.

[weiji14]

Erm, but I do see it on crates.io at https://crates.io/crates/geotiff 😅 It seems like someone published it about three years ago?

[dominikbucher]

Oh, ups, yeah that might have been as part of the transition to the georust org. Thanks for noticing!
