This morning I uploaded this file--a geospatial pdf. This shows 3 watersheds in Ethiopia and lets the user check their phone and figure out where they are relative to watershed boundaries. Why would I want to do this? Knowing where you are in a watershed is important to planning for example for tree planting activities. The upper parts of a watershed tend to be especially critical and are often the source of rivers that supply water to the rest of the system. Knowing where you are then means you can decide where is best to plant and what is best to plant. A simple file like this, easy to read on any phone can help farmers make the best use of their time and resources in restoring the environment.
