Saudi Arabia has a long Red Sea coast, elevated terrain in the west, and broad dry interior regions. In detailed imagery, centre-pivot irrigation can appear as circles within the desert. The Empty Quarter occupies much of the southeast of the Arabian Peninsula.
The Red Sea margin and the interior deserts
Compare the western highlands near the Red Sea with the broad interior. The regional overview is too coarse to identify individual farms; use a closer image for that task.
Similar landscapes across borders
Circular irrigation is used in many countries, and dunes extend beyond Saudi Arabia. Oman, the UAE, and other neighbours share dry landscapes. Check the mountain front or coastline as well as the field pattern.
