min_zoom revisions and other final cleanups

[nvkelso]

In performing QA for https://github.com/nvkelso/natural-earth-vector/issues/202 a few issues have come up...

• [x] countries should have a min_zoom (almost always 0) and a min_label
  • [x] don't leave the 50m or 110m tiny country points behind
  • [x] also disputed areas, take from their boundary line min_zoom – else Kashmir is a mire 😢
    • [ ] May need to x-fade disputed areas / labels into zoom 8 over OSM in implementations like Tilezen?
• [x] states should have a min_zoom (almost always 0) and a min_label
• [x] adjust min_zoom values
  • [ ] 10m, 50m, 110m coastline min_zoom needs to match land scale rank min_zoom
  • [x] 110m physical label areas should only have continents (not others)
  • [x] 50m disputed boundary polygons Kiril from 1.7 to 3
  • [x] 50m physical label areas still too dense
    • [x] downgrade most in Asia
  • [x] 10m marine polygons are suspicious at zoom 3
  • [x] 10m countries GUAM to zoom 3
  • [x] 10m countries ST PIER AND MIQ. to zoom 5
  • [x] 10m admin1 lines, polygons
    • [x] JAPAN lines to min_zoom 7 (was 3) ... the polygons should go to 7 or 8? other changes like this already made?
  • [x] 10m for 110 populated places min_label
    • [x] New York to 1.7
    • [x] Rio to 1.7
    • [x] Cape Town to 1.7
    • [x] Paris to 1.7
    • [x] London to 1.7
    • [x] Moscow to 1.7
    • [x] Beijing to 1.7
    • [x] Tokyo to 1.7
    • [x] Sydney to 1.7
  • [x] 10m populated places this is rank_max and rank_min already
    • [x] add pop_rank, see WOF
  • [x] 10m countries
    • [x] add pop_rank, see WOF
  • [x] country min_label
    • [x] Japan to 1.7????
    • [x] Bolivia to 3.0
    • [x] Ven to 3.0
    • [x] Angola to 3.0
    • [x] Namibia to 3.0
    • [x] Mali to 3.0
    • [x] Algeria to 3.0
    • [x] Poland to 3.0
    • [x] Ukraine to 3.0
    • [x] Norway, Finland, Sweden to 3.0
    • [x] Iraq to 3.0
    • [x] Iran to 3.0
    • [x] Saudi Arabia to 3.0
    • [x] Afghanistan to 3.0
    • [x] Pakistan to 3.0
    • [x] Kazikstan to 3.0
    • [x] Mongolia to 3.0
    • [x] South Korea to 3.0
    • [x] Philipeans to 3.0
    • [x] PNG to 3.0
• [ ] random stuff
  • [ ] 10m roads are used on the zoom 2, 3, and 4!?
    • [ ] this is correct, but maybe we should have a 50m roads layer then? Would need x-fade instructions for an implementation like Tilezen
  • [x] 10m land scale rank has an extra scalerank_ field?
  • [x] 10m admin 1
    • [x] some should still show up in the 50m range?! at least zoom 4, maybe zoom 3?
    • [x] This is really 4.6 in the 10m file already
    • [x] limit min_label to 5 instead of 4.6 though?
  • [x] physical areas need to know if they dup an admin name (like Cuba)
  • [x] canada (possibly other) adm1 max_label needs to go from 5 to 7
  • [x] the geography areas & etc should be min_label and max_label (not zoom)?!
  • [x] should geographic lines get a max_zoom?
    • [ ] showing inclusive to zoom 7 is fine
  • [x] non-USA state labels dont' show up? see Europe
  • [ ] (minor) islands of Norway missing
  • [x] 10m rivers
    • [x] too many (parenthetical) names still, especially in India/China
    • [x] add min_label attr
  • [x] USA map unit needs the full consistent name "United States of America"

For population_rank (or pop_rank because SHP 10 char column name limits):

if population >= 1000000000: 
    population_rank = 18
elif population >= 100000000: 
    population_rank = 17
elif population >= 50000000: 
    population_rank = 16
elif population >= 20000000: 
    population_rank = 15
elif population >= 10000000: 
    population_rank = 14
elif population>= 5000000:
    population_rank = 13
elif population>= 1000000:
    population_rank = 12
elif population >= 500000:
    population_rank = 11
elif population >= 200000:
    population_rank = 10
elif population >= 100000:
    population_rank = 9
elif population >= 50000:
    population_rank = 8
elif population >= 20000:
    population_rank = 7
elif population >= 10000:
    population_rank = 6
elif population >= 5000:
    population_rank = 5
elif population >= 2000:
    population_rank = 4
elif population >= 1000:
    population_rank = 3
elif population >= 200:
    population_rank = 2
elif population > 0:
    population_rank = 1

physical areas need to know if they dup an admin name (like Cuba)

This should be resolved by collision rank instead in the style.

UPDATE: This still fails Greenland, but mostly works looking at basic QGIS config.

[nvkelso]

so disputed areas, take from their boundary line min_zoom – else Kashmir is a mire

Is mostly working but Kashmire needs a little more work

[nvkelso]

10m, 50m, 110m coastline min_zoom needs to match land scale rank min_zoom

I think this is the last big thing left besides zipping everything up and posting v4 of Natural Earth to the public site?

Coastlines were 99.9% good, couple dozen edits in https://github.com/nvkelso/natural-earth-vector/commit/63b9b086899311673b408ffbf846a45b88e735bb.

Let's call this done :)
