Our early warning products include crop growth conditions, drought and desertification indices, rainfall maps and more. These generic binary data products can be imported in almost any GIS and viewed as quantitative spatially continuous maps. To make it easier for interested visitors to evaluate our products, we have developed a software tool called ImageShow, meant only for displaying purposes and simple analysis. You can download ImageShow on this page as well as sample products of the following regions: East Africa, Sahel region and Southern Africa.
