Inequality isn’t just about money. It’s also about information. The lack of reliable data about developing countries makes things like development work and disaster relief much harder.
There is ‘mapping inequality’ throughout the world; poorer countries often don’t have comprehensive census information and geospatial data. Crowdsourced mapping is seeking to change and improve geographic awareness, especially in moments of crisis. For example the maps of Sierra Leone, Liberia and Guinea were essentially blank at the beginning of the Ebola outbreak but that glaring need meant volunteers were using geographic tools to improve developmental situations by providing more information.
