I've got a list of some hundreds of latitude/longitude pairs close to each other (within a country). I want to create an image with a map, and circles overlaid around these points. Basically, what I need is:
- an image of a map
- a way of translating latitude/longitude pairs to pixels
Where can I obtain a fitting map (e.g. roadmap or satellite map) with the parameters needed to plot the points? I suppose there is some FOSS tool that does most of this already?
