Answer:
The highest location is situated where is the highest altitude.
For that, you must look at the numbers from the level curves on the map.
Location 1 is situated between 160 m and 180 m, but near 180 m.
The approximate altitude will be 175 m.
Location 2 is situated between 200 m and 220 m. We will approximate the altitude: 210 m.
Location 3 is situated on 140 m.
Location 4 is situated near 240 m.
The order of location from highest elevation to lowest elevation is:
- location 4
- location 2
- location 1
- location 3
