Automatic list with overviews of inlcuded area definitions for the documentation #2167

BENR0 · 2022-08-05T18:18:48Z

Based on pytroll/pyresample#450 this generates overviews for all AreaDefinitions included with Satpy and adds them to the resampling section.

I noticed that a quite large number of AreaDefinitions are included which make the section really long now.
Some areas are not included because only AreaDefinitions currently have _repr_html_ (see PR above).

This looks interesting. How easy would it be for users to use this feature to generate overviews of areas from their own local YAML files?

Doesn't this function rather belong to pyresample?

I think it doesn't really make sense to include in in pyresample because there is no area definition yaml included and this is only useful to generate a rst with a list of area definitions for the documentation.

It is true that pyresample does not have a default yaml file, but it is pyresample that contains all the functions for reading such yaml files. And also, I would argue that for the sake of separation of concerns, it should be included there.
In practice, I wouldn't be against having a default yaml file with a few generic areas in pyresample by the way, that would probably help potential pyresample users in the future...

Wouldn't areas.yaml fit better with pyresample entirely? But pyresample does not have a concept of SATPY_CONFIG_PATH or a config directory search, so it wouldn't know where to find areas.yaml anyway?

Not that anyone asked for my opinion, but I agree with wanting this in pyresample. I'm not a big fan of a default set of areas in pyresample except only as a few examples (like global lon/lat, one LCC, one polar-stereographic, etc)...generic areas. Pyresample is the low-level functionality, but it doesn't know anything about satellite-specific areas or that it is used for "science" at all so to me it is a fine line.

A while ago, I found a small list of generic areas, like europe, north and south america, etc. I'll try to find it again, so we can use that.

would this work? https://cfconventions.org/Data/standardized-region-list/standardized-region-list.current.html

As far as I see, those are just area names without defining anything AreaDefinitiony that we could use.

@gerritholl Curently not that easy I guess. But could easily be refactored to be available to users I think.

@gerritholl Curently not that easy I guess. But could easily be refactored to be available to users I think.

Especially if it was in pyresample 😉

BENR0 · 2022-08-12T10:48:57Z

@mraspaud @gerritholl ok so where should this go in pyresample? Should I include it in pytroll/pyresample#450 or make a separate PR?

LGTM. A screenshot would be nice :-)

BENR0 · 2022-11-18T10:12:03Z

Since this is based on the area html representation is has the same features (properties list/ foldable map).
So this is how it looks like:

Folded

There are some problems with building the documentation, but they seem to be because pytroll/pyresample#450 needs to be merged and released first.

BENR0 · 2022-11-28T12:21:23Z

There are some problems with building the documentation, but they seem to be because pytroll/pyresample#450 needs to be merged and released first.

Yes correct. Based on some discussions and ideas I had I am working on making this more useable/pretty so please wait with merging this even if pytroll/pyresample#450 gets merged in the meantime.

BENR0 · 2022-12-05T14:03:10Z

Since there are quite a few AreaDefinitions in the yaml file I added a searchable table similar to the reader table with links to the definitions so the user does not have to scroll through the whole document. Currently this is still a bit messy since I just included the generation in the conf.py of the documentation for demonstration purposes. If this is wanted I will refactor this. It could be integrated into the generation function I already moved to pyresample but there on its own it would just generated a static table because the searching and sorting depends on the datatable css and js which is integrated in the satpy documentation.

Below you can see how it would look like. One think to note is that all the area definitions also appear in the toc tree which is not a huge deal but not that nice I guess. I think that has something to do with the toc maxdepth setting but I couldn't get that fixed somehow. So if somebody has an idea about that please share.

Apart from that I notice that there are two area definitions I think belong to DynamicAreaDefinitions?:

omerc_bb
laea_bb
Right now these produce broken links in the table because obviously there can be no overview generated for those.

pytroll/pyresample#450 is now merged. Do we need a pyresample release before this can work?

BENR0 · 2023-12-13T09:22:30Z

I think so because if I see correctly read the docs uses a conda installed pyresample to build the docs.
While the table should build fine in either case it would be nice to have the area names in the yaml file fixed (even if there is no agreement on a file naming pattern yet) #2310.

gerritholl · 2023-12-14T11:37:26Z

You can add yourself to AUTHORS.md while you're at it :)

mraspaud

I think this can be merged, thanks for the adding it. The filling for water bodies is not always working, but that needs to be fixed in pyresample.
