update example in request-params.Rmd

[maelle]

We have this example code in a pkgdown article

library(EMODnetWFS)

wfs <- emodnet_init_wfs_client("human_activities")

emodnet_get_layers(
  wfs = wfs,
  layers = "maritimebnds",
  featureID = "maritimebnds.861",
  reduce_layers = TRUE
)

However "martimebnds" seems to no longer be a layer for this service.

@salvafern I have two questions

• is that "maritimebnds" boundary in another service? Did it just disappear? How would user know about changes in available layers?
• do you know of another example we could use instead in the article. It needs to be a layer with featureIDs (not sure where to find those), a feature we can use to sortBy, enough features for startIndex to be interesting, propertyName to be useful, and it needs geometry to demonstrate filtering by a box. Also how can we choose one that doesn't disappear?

This layer was temporaly removed from EMODnet due to lifewatch/marineregions-issues#13 - we will update the maritime boundaries product in the next release.

I would say better to not use layers from Human Activities as anything with a political content is more prone to change / disappear. In general layers should not be taken down but I wouldn't be surprised if it happens again without notification. Not sure I have a solution.

I will look for a layer that works as an example

Thank you! I'll wait for an update from you then. 🙏

@salvafern Friendly reminder 😸

@salvafern any update? 😺

@salvafern friendly reminder 🙂

Apologies for overlooking this. I cannot find an example outside human activities, it might be that it is the only lot that uses featureID.

An example in human activities is the layer "pipelines":

library(EMODnetWFS)

wfs <- emodnet_init_wfs_client("human_activities")

#> Loading ISO 19115 codelists...

emodnet_get_layers(
    wfs = wfs,
    layers = "pipelines",
    featureID = "pipelines.1",
    reduce_layers = TRUE
)

^{Created on 2024-06-25 with reprex v2.1.0}

I added a new branch and updated the article. But there are other places in the package where the Maritime Boundaries layer is mentioned (vignette EMODnetWFS and one of the test).

Thank you!! I removed the example from the main vignette. It's a pity!
