Data Problems > Terrain Errors > Polar depressions
The Compendium Table of Contents contains a single network link which enables you to download the latest version of the entire Compendium in a single file of about 1.1 megabytes.
____________________
The north and south polar areas do not display elevation (altitude) data, so they are shown at 0 elevation when TERRAIN is turned ON. We show the borders of the 0 elevation areas.
---- There is no elevation data north of 77° 30' N
---- There is no elevation data south of 77° 30' S
We show detailed outlines of the four arctic areas affected:
---- Canada: Ellesmere Island
---- Denmark: Greenland
---- Norway: Svalbard
---- Russia: Franz Josef Land, Ushakov and other islands, and Komsomolets Island (Severnaya Zemlya)

Data Problems > Border & Coastline Problems
The Compendium Table of Contents contains a single network link which enables you to download the latest version of the entire Compendium in a single file of about 1.1 megabytes.
____________________
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.

MULTIPLE LAYERS
PaginasAmarillas.es provided the data for many layers in Spain for both Google Earth and Maps. The layers of concern are Dining, Community Services, Lodging, Shopping & Services, and Transportation. We show areas of placemarks which are displaced into the ocean, and the town in which they should be located.
Canary Islands
---- Fuerteventura, Puerto de la Peña (1.5 kilometers west) and Puerto del Rosario (3,000 kilometers north, and 245 kilometers northwest of Ireland, noted by Noel_B, 20 June 2007)
---- Gomera, San Sebastián (3 kilometers east)
---- Gran Canaria, Las Palmas (four areas 5 to 50 kilometers east)
---- Tenerife, Puerto de la Cruz (360 kilometers east)
Miscellaneous Spanish locations can also be found about 500 kilometers south of the Côte d'Ivoire
