BORDERS

Ceuta & Melilla borders (3813)
Chilean-Argentine border Dispute (529241) and Villa O'Higgins
Estonia - Piiriissaare [Пиириссаара] (3694)
Indonesia - False 1st admin border (3788)
Mali-Mauritania broken border (644081)
Netherlands - Gronigen-Drenthe border (644120)
In the Spring of 2006, the border/boundary mechanisms were changed to a low resolution US-Canadian border, which is wrong by a mile is some places. We show such an area at the "triple point" of Quebec, New Hampshire, and Vermont. See Official Canada-USA Boundaries for an accurate downloadable border.
The previously missing Nunavut Canada boundaries are now supplied with Google Earth, but they differ in details from THIS POSTING which provides a downloadable file. The file contains a link to the legal definition from the Nunavut Planning Commission.

COASTLINES

Coastlines changed the way they are displayed north of 81° 33' 50" N and south of 81° 33' 50" S, shown in the attached file. These boundaries were moved towards the poles in Spring 2006. The coastlines are now displayed in the following peculiar ways:

With a minimal window size (820 x 470)
---- towards the nearby pole at altitudes of 10-200 and above 800 kilometers
---- towards the equator at altitudes of 10-40 and above 200 kilometers

With a large window size (for example, 1800 x 1440)
---- towards the nearby pole at altitudes of 30-300 and above 2000 kilometers
---- towards the equator at altitudes of 30-100 and above 600 kilometers

Because coastlines are are narrow yellow lines, they are almost invisible in polar ice-covered regions.
617779 US Kingman Reef coastline seems to be a GIF extracted from the CIA Factbook map, and it is 12 times too large. The most accurate map available online appears to be from US Fish & Wildlife. We provide a corrected coastline based on the CIA map, which may be used by anyone without attribution. 12 January 2006

The original data error appears to come from the USGS Data.
