GNIS Redirect

[dblodgett-usgs]

Now that a GNIS app is available, I think we should go ahead and mint GNIS redirects. I've reached out to the team working on the app and will try and get some dialogue going here.

Will need to create a template. Since we can proxy the esri service, it *may not be necessary for you to prepare any data (although probaly we want a jsonld graph to import directly), unless you want to make links to other data that can't be generated on the fly from the data in the service.

[ksonda]

Yeah on thinking about this more this may be a good opportunity to experiment with generating a json-ld graph for bulk import

[ksonda]

Per discussion on slack, I'm thinking the best thing to do is to

1. Mint PIDS like https://geoconnex.us/ref/gnis/[featureID]
2. redirect those to a collection in reference.geoconnex.us. To keep it updated, implement a monthly update of the gnis-data download
3. Include subjectOF links to nationalmap and wikipedia, sameAs links to gnis-ld.org and wikidata and ref/counties, ref/states, ref/mainstems perhaps

starting a repo that will include CI with hydroshare https://github.com/cgs-earth/ref_gnis

[ksonda]

when we do this, we should update the GNIS urls in all reference features that were using the Apex urls

Bumping this issue per a recent email thread with the National Map People.

I think we

1. Mint geoconnex.us/usgs/gnis/<gaz_id> as a regex redirect to https://edits.nationalmap.gov/apps/gaz-domestic/public/summary/<gaz_id>

2. Mint geoconnex.us/iow/gnis/<collection_type>/<gaz_id> to

• redirect to a pygeoapi we set up with appropriate JSON-LD templates that proxies each of the layers on this esri MapServer https://carto.nationalmap.gov/arcgis/rest/services/geonames/MapServer
• the JSON-LD templates here include a owl:sameAs geoconnex.us/usgs/gnis/<gaz_id>

3. for other integrations we do, we advise using geoconnex.us/usgs/gnis/<gaz_id>, but our graph will merge in the geospatial and name info from geoconnex.us/iow/gnis/<collection_type>/<gaz_id> until such time as TNM has a stable semantic version of GNIS out there that we can redirect geoconnex.us/usgs/gnis/<gaz_id> to.

Thumbs up from me!
