About
Internal, first-order administrative boundaries and polygons for just the United States and Canada at this time. For more detailed breakdowns for most countries in the world, see 10m admin-1. Boundary lines do not duplicate each other. Boundary lines are only present on internal boundaries (not coastlines or admin-0 boundaries).

About Point symbols with name attributes. Includes all admin-0 and many admin-1 capitals, major cities and towns, plus a sampling of smaller towns in sparsely inhabited regions. We favor regional significance over population census in determining our selection of places. Use the scale rankings to filter the number of towns that appear on your map.
LandScan derived population estimates are provided for 90% of our cities. Those lacking population estimates are often in sparsely inhabited areas. We provide a range of ...
Glaciated Areas
Includes glaciers and recently de-glaciated areas.
[drain file 63 show nev_download]
About
Polygons derived from DCW (Digital Chart of the World), except for Antarctica derived from MOA. Includes name attributes for major polar glaciers. Filtering has aggregated some minor glaciers and eliminated others from the original DCW data.
(below) Glaciated areas near Anchorage, Alaska.
Issues
Needs scale rank attributes.
Note: The original DCW data was collected decades ago. Since then many mountain glaciers have either disappeared or diminished in size. This data theme is deliberately called "glaciated areas" instead of "glaciers" to reflect the changeable character of glacier extents.

About
Tiny country points: Some countries don't read well on thematic choropleth data maps. Color code the dots with the same information as the larger country polygons to communicate data that would otherwise be lost.
Sovereign states: There are fewer sovereign states than ISO country codes. Sovereign States do not distinguish between the metropolitan and semi-independent portions of a state or it's constituent countries. ...

[drain file 335 show nev_download]
About
Countries distinguish between metropolitan (homeland) and independent and semi-independent portions of sovereign states. If you want to see the dependent overseas regions broken out (like in ISO codes, see France for example), use map units instead.
Each country is coded with a world region that roughly follows the United Nations setup.
Countries are coded with standard ISO and FIPS codes. French INSEE codes are also included.
Includes some thematic data from the United Nations (1), ...
Parks and Protected Lands

About
Data includes the 398 authorized National Park Service units in the United States only. The data does not include affiliated areas and unauthorized park units. We'd like to include more national parks from around the world, see issues below.
Park units over 100,000 acres appear as areas, park units under 100,000 acres as points, and linear parks, including rivers, trails, and seashores, as lines. There are a few exceptions to this rule.
(below) Units in the southern United States include Great Smoky Mountains National Park, ...

About
Major coral reefs from WDB2.
(below) Australia and Papua New Guinea reefs.
Issues
Great barrier reef off Australia and reefs elsewhere could use better definition. Should replace entire dataset with VMAP0 reefs, which will require considerable generalization and fitting to coastlines and atolls.
