convenient function to get the field raster metadata.

[lazarusA]

Currently, using metadata

metadata(ras_resample)
Metadata{Rasters.GDALsource} of Dict{String, Any} with 4 entries:
  "units"    => ""
  "offset"   => 0.0
  "filepath" => "/vsimem/tmp"
  "scale"    => 1.0

but getting this info seems to take more effort:

├───────────────────────────────────────────────────── raster ┤
  extent: Extent(X = (-180.0, 180.0), Y = (-90.0, 90.0))
  missingval: NaN32
  crs: EPSG:4326
└─────────────────────────────────────────────────────────────┘

namely, ras_sample.missingval, crs(ras_sample) and extent(ras_sample), where all of them output different types, hence a convenient function that outputs a Dict similar to the one from metadata would be nice to have.

There is also missingval(ras_sample).

I'm not sure about this one. How often would you really need all of these three properties in one object? They don't really have much in common other than that they are shown together.

[lazarusA]

ideally, I would like to have only one function to get all metadata information.

[tiemvanderdeure]

But then what should count as metadata? If I load a Raster lazily, the file path appears in the same box (or at least it should). But this would be a bit weird to include as it doesn't say much about the actual object. On the other hand the sampling (point-based vs intervals) is more closely related to crs/extent, but it doesn't appear in that box. I don't really see a way to design that that fits everyone's needs here.

sampling (point-based vs intervals)

yes, I also noticed that one, and probably should also be included. Probably, best will to output collect as much as possible and then let users decide what to leave out.
