1. The chart depicts areas of the northern and eastern hemispheres.

2. First, locate the parallel of latitude 48°N and the meridian of longitude 013°E.

3. The longitude increases as we move eastwards and each small line along a parallel corresponds to 1 minute of arc.

4. So, from the meridian 013°E count 39 more minutes of arc (small lines) along the parallel 48°N eastwards to find the 013°39'E longitude.

5. Also, the latitude decreases as we move southwards and each small line along a meridian corresponds to 1 minute of arc.

6. So, from the parallel 48°N count 7 more minutes of arc (small lines) along the meridian 013°E southwards to find the 47°53'N latitude.

7. The intersection between the latitude 47°53'N and longitude 013°39'E is a peak with elevation of 3399 ft AMSL.
