Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software. ...
Because vector data have vertices and paths, this means that the graphical output is generally more aesthetically pleasing. Furthermore, it gives higher geographic accuracy because data isn’t dependent on grid size. Topology rules can help data integrity with vector data models. Not only that, ne...
Raster data is most commonly found in remotely sensed data, shaded relief and topographic data, satellite imagery, and aerial imagery. When you zoom in on raster data like this shaded relief layer, you can see each cell is the same size. Images: Caitlin Dempsey. Vector data Vector data is...
