Question
If you had a GIS data layer for Europe, which of the following would be likely Datums?
- WGS84
- NAD27
- NAD83
- UTM 17N
Solution
The likely datums for a GIS data layer for Europe would be WGS84 and UTM 17N.
Here's why:
-
WGS84: The World Geodetic System of 1984 is used worldwide and is the datum used by GPS. It's a global datum and reference system that accurately represents the shape of the Earth.
-
UTM 17N: The Universal Transverse Mercator coordinate system divides the Earth into 60 zones, each 6 degrees of longitude wide. Zone 17N covers part of the Atlantic Ocean, which is west of Europe, but it could be used if the data layer includes parts of the Atlantic.
On the other hand:
- NAD27 and NAD83: The North American Datum of 1927 and 1983 are used mainly in North America, and wouldn't typically be used for a data layer focusing on Europe.
