Replace HOTOSM layers?

[trey-stafford]

Can we replace the HOTOSM layers with something else, e.g., from Asiaq?

Aside from populated places, HOTOSM layers were:

• "health_facilities"
• "airports"
• "seaports"
• "waterways"
• "financial_services"
• "education_facilities"
• "points_of_interest"
• "roads"
• "buildings"

Frederik H. from Asiaq says:

You can find the data here: https://kort.nunagis.gl/refserver/rest/services/Kortportal/Kortportal_TekniskGrundkort/MapServer

The building layer is called ‘BYGNING’, and the attribute containing building use is called ‘Info’. It is only in Danish though.

I was able to get a json response for the buildings layer with the following url: https://kort.nunagis.gl/refserver/rest/services/Kortportal/Kortportal_TekniskGrundkort/MapServer/82/query/?f=json&where=OBJECTID+is+not+null&outFields=*&orderByFields=OBJECTID+ASC

PR #568 adds buildings layer. Attributes are in Danish.

The "Bygningsbrug" field gives the building use. Unique values are (translated to English via Google Translate):

• Health center
• Museum
• Church
• Children's institution
• Hotel
• Store
• Sports hall
• Police station
• Telecom building
• Powerplant
• Incinerator
• Assembly hall
• Fire station
• Airport
• School
• water plant
• Retirement home
• Fishing facility
• District office
• Chapel
• Municipal office
• Circuit Court
• Service house
• Nursing station
• College
• Postoffice
• School / Chapel
• Transformer station
• The board
• Village consultation
• Kiosk
• Central heating
• library
• town hall
• Institution for convicts
• Hospital
• Hostel
• Cogeneration plant

So we could create e.g., an "Airports" layer from "Buildings".

PR #569 adds a roads layer from the same NunaGIS service as the Buildings layer.

The layer is titled "VEJMIDTE" in the service, which translates to "MIDDLE OF THE ROAD" according to Google Translate. I think this means the lines are roadway centerlines, which is probably what we want. I'll follow up with our contacts as Asiaq to confirm though.

Other layers we might be interested in from the NunaGIS service:

• NATURSTI (nature trail)
• HELIPORT (heliport)
• HELISTOP (helistop)

PR for various layers added from Asiaq/NunaGIS: #571

Still need to find a "populated places" layer: something that has a population count. Some of our tutorial materials rely on this.
