GPStogo
GPStogo is a scheme for providing GPS receivers, for the purpose of contributing to OSM, to people in developing countries where the cost is otherwise prohibitively expensive.
The OpenStreetMap Foundation, who are the operators of this scheme, aims to donate GPS units, on a long-term basis, to suitably qualified people in any developing country.
If you have an old GPS receiver that you no longer use then it may be possible to donate this to someone directly.
Recipients
Please contact the Humanitarian OpenStreetMap Team (HOT) if you would like to receive a device for use in a developing country.
