Sanctuaries polygons from zip files are hard coded?

[MathewBiddle]

I was interested in doing a quick analysis of how much the Sanctuaries polygons overlay with IOOS RA polygons (MathewBiddle/sandbox#6) and I recalled that seascapeR pulls in the Sanctuary polygons.

After some sleuthing, I can see that it looks like you pull in the polygons via hardcoded urls to the zip packages available at https://sanctuaries.noaa.gov/library/imast_gis.html

seascapeR/R/read.R

Lines 86 to 92 in 1f3ecc9

	url <- case_when(
	sanctuary == "mbpr" ~
	glue("https://sanctuaries.noaa.gov/media/gis/{sanctuary}_py.zip"),
	sanctuary == "pmnm" ~
	glue("https://sanctuaries.noaa.gov/library/imast/{sanctuary}_py.zip"),
	T ~
	glue("https://sanctuaries.noaa.gov/library/imast/{sanctuary}_py2.zip"))

My question is, has anyone tried to reach out to ONMS to see if those shapefiles/polygons can be made available via a webservice, like WMS/WFS or something OGC compliant? Even as geojson endpoints would be helpful.

Here is the whole get_url_ply function:

I haven't heard any discussion about that. If we are going to set up a service I might like to do something similar with the NERRS boundaries and other RoIs we frequently analyze.

NOTE: this function is in extractR also: https://github.com/marinebon/extractr/blob/main/R/read.R#L69-L153

Found the arcgis service https://services2.arcgis.com/C8EMgrsFcRFL6LrL/arcgis/rest/services/NOAA_National_Marine_Sanctuaries_(2023)_/FeatureServer

I was able to read in the layers and put them on a map in this gist, if you're curious:

Hi @MathewBiddle,

Yeah, it's preferred to have the sanctuaries as a web service. These were compiled originally for onmsR::sanctuaries and here's the geojson produced by onmsR: data-raw/sanctuaries.R:

• onmsR: data-raw/sanctuaries.geojson
  

More recently I added the Chumash Proposed NMS in calcofi4r::cc_places with the intent of adding this back to onmsR::sanctuaries.

You rightly point out the need for spatial web services to these spatial features. To this end, I hope to make vector tile services using pg_tileserv.

Interesting 🤔 . It looks like Papahānaumokuākea is not in the arcgis service

Service updated...should be good to go now.

Thanks @mimidiorio!

Here is one for NERRs.

Happy to publish other ROIs as needed. Just ping me. The whole MPA Inventory is here.
