ShareAlike copyright question

To what extent does a map using ShareAlike data require that the rest of the publication is ShareAlike?

Let's assume that the map in these examples is made from ShareAlike data.

1. Separate pages

Map on one page, non-map information on the other. This should be the easiest case.

2. Same page

This is exactly the same as the previous map, but the map and the non-map information are on the same page. (For what it's worth, this is the real map.)

3. Same page, with label

Pretty much the same as 2, but there's a little line linking the non-map information to a place on the map.

4. Same page, placed on map

This is similar to 3, but instead of keeping the map at the bottom and linking it by a line, it's placed next to the relevant feature - effectively using it as a label.
