When looking through the latest imagery update in Google Earth, we came across some images in northern Uganda. They were captured by DigitalGlobe as part of their ‘FirstLook’ programme and relate to the movement of refugees from South Sudan into Uganda. There is ongoing violence in South Sudan, which has in turn created a famine in the region. The combination is causing many people to flee the country. According to Wikipedia, the refugee camp is named Bidi Bidi, and with over 270,000 residents is the largest refugee settlement in the world.

Unfortunately, the DigitalGlobe image does not capture the full extent of the Bidi Bidi camps and only shows the southern edge of one new section that has appeared recently.

So, we downloaded a recent Sentinel-2 image of the region and were able to identify a number of camps that have appeared at various times starting in 2014. We also had a look at this list of the world’s largest refugee camps and were able to locate most of them.

Refugee camps are quite distinctive in satellite imagery. They typically have a large grid pattern of road networks, which are not typical of that part of Africa. Small towns in the region typically grow slowly and more organically, resulting in a less ordered layout than refugee settlements which are planned and built in short bursts.

Some of the largest refugee camps are a collection of five camps in Kenya near the border with Somalia. The southernmost camp was clearly over-planned, with a vast network of streets laid out, but only a small portion ever occupied:
