We developed Natural Earth as a convenient resource for making custom maps. Unlike other map data intended for scientific analysis or military mapping, Natural Earth is designed to meet the needs of production cartographers using a variety of software applications. Maximum flexibility is a goal. Natural Earth Vector comes in ESRI shapefile format, the de facto standard for vector geodata.
