We are used to seeing global maps of the more familiar equatorial-aspect (or normal) Mercator projection, which depicts parallels and meridians as perfectly straight lines parallel to the x and y axes: So at first, your result may seem surprising, as you noticed differing latitudes for a specific northing in UTM, however UTM uses a transverse aspect. How did the OS/360 link editor achieve overlay structuring at linkage time without annotations in the source code? First, ETRS 89 is a geographic coordinate system, so you cannot compare it directly with UTM (a projected coordiante system). The UTM system (Table 1) uses the TM projection and attempts to overcome this limitation by dividing the Earth into 60 zones, each with a width of six degrees of longitude. 500,000 m. False Northing (in the southern hemisphere) 10,000,000 m. Figure 2: Relationship between geographic coordinates and projected coordinates. Nearly always when the term "latitude" is used without any qualifier, the geodetic (or geographic) latitude is meant.

Unless you are dealing with data from a couple of exceptional areas (Svalbard and parts of Norway), this is a simple enough calculation that you might as well just do it yourself in R. Here is Wikipedia's description of how longitude relates to UTM Zone number: The UTM system divides the surface of Earth between 80S and 84N latitude into 60 zones, each 6 of longitude in width. Granted, UTM does not use a single, full extent projection, but it instead uses 60 6-degree bands centered on some central meridians in order to use the area of the projection with minimal distortion, but for the sake of the present visualization, I'm going to use the full projection, but the principle holds for smaller regions too.. Notice how, when we draw straight northing (horizontal) lines on that projection, they do not follow latitude lines anymore (except for the Equator): Hence, it is perfectly normal that a specific northing corresponds to slightly different latitudes, depending on the easting.
