[Tagging] Highway classification in Antarctica

Fri Apr 26 06:12:48 UTC 2024

About King George Island, if I am not wrong, the normal people can not reach the island from any ferry neither commercial flights from the rest of the world. You can only reach the island using a cargo aircraft.
Inside the island you can not drive a motor vehicle, in the best case only can walk or be transported by special staff. Probably tourists can only move between the aerodrome and Villa Las Estrellas. It is a restrictive place for the general public, therefore it does not seem useful to use a higher classification than highway=unclassified.

Country-specific conventions are based on the international definitions. The latter should be sufficient and any local consideration does not imply a redefinition of the tag. The "assumptions" section of the wiki explains the case of a whole road network with bad infrastructure. There are no road network in King George Island, only a few short roads to serving research stations. I think the default value should be unclassified (or service if the road leads to a single building) and from that discuss if is necessary to elevate classification to highway=tertiary. Secondary value seems clearly wrong for the island.

Also there are questionable tertiary roads before tagged as highway=unclassified/residential in stations Fortín Sargento Cabral and Marambio, included conversions from place=hamlet to place=village and a highway=unclassified towards the summit of Mount Vinson.

Regards.

Asunto: [Tagging] Highway classification in Antarctica

As Antarctica is international space,[1] I understand that, in
principle, the highway classification scheme of no particular country
applies there. For a while, I tried to come up with a balanced generic
scheme based on the regional importance of these roads,[2] which has
been questioned,[3] so I would like to hear opinions on the matter.

Should the classification of highways in Antarctica:

1. Follow country-specific conventions near stations? This can lead to
different classifications for long polar traverses maintained by
different countries and can create disconnected road networks (in
terms of classification) between nearby stations operated by different
countries.

2. Follow generic OSM definitions based on absolute population
thresholds of the places they connect? (10k+ people for town, 1k for
village, 100 for hamlet, etc.) This will assign very low road classes
across the continent.

3. Follow generic OSM definitions based on lower place population
thresholds that are more compatible with the reality of the continent,
based on regional importance? [4] The result may be perceived by some
as assigning higher than normal highway classes to the connections
between these small settlements.

Additionally, should the permanent population be considered (zero in
most cases, which is the case even for larger stations, further
lowering highway classification), or the average occupancy of the
stations?
