Finding data online for Tanzania has proved to be a bit of a challenge. This article provides an overview of publicly available sources. We are sure more exists, so just post comments to this message and we will keep updating the table.
Ideally data should be provided by its owners with appropriate meta data. We have decided to minimize our provisions of data because of this. You will find the sources not to be the original ones, but the files might still be useful.
Your input to this process is desired. Please use the commenting system to point us in the right direction for our effort to make an initial meta database for spatial data in Tanzania.
