5 Ways to Vectorize Maps – wikiHow
If you would like to make or translate maps but don’t know where to start, this guide is for you. If you would like to begin making vector graphics but you are not yet fluent with Inkscape, making maps is excellent practice. To make maps you don’t need to know how to draw. The only talent you’ll need is patience and the ability to follow a series of steps. Sadly, the majority of maps available are in png, gif, or jpg (which is to say raster formats) and at poor resolution. This has many disadvantages: These problems are solved by using vector graphics. Basically, while raster graphics contain information about color at each point, vector graphics contain parameters that define the shapes (see related articles below). Inkscape is a free program to work with vector graphics, and it is the program used in this guide. Source.
