Not all countries have the benefit of funding/technologies for developing GIS data stores. I'm looking for a list of common GIS data sources that should be investigated when trying to build a good basis for GIS analysis in developing nations (e.g road/river networks, DEMs, land use). Free or paid data.
My first stop is usually Glovis for Landsat coverage, but I often come up short on vector data.
For example, I would like to create a series of thematic maps for Nepal containing any and all GIS information I can get my hands on. Where would you begin?
Organizational sources could also be useful, even if their data is not available online. E.g contacting the government department in charge of water resources.
