[GIS] Where can i find Latitude & Longitude data for the coastlines of the world

datalatitude longitude

Im developing an application to print flight paths on a world map.

To do this i need a dataset to describe the latitude and longitude of various coastlines (and country borders if possible) of the world so I can plot them.

Is there anywhere on the web I can find this kind of data? (preferably free/cheap)

Thanks!

Natural Earth would be the place to go. The data is open source and generalised for use at different scales.
