I do something very similar in ROSshow for NavSatFix (GPS) messages: https://github.com/dheera/rosshow https://github.com/dheera/rosshow https://github.com/dheera/rosshow/raw/master/screenshot3.png?raw=true https://github.com/dheera/rosshow/raw/master/screenshot3.png... It also has a pure ASCII mode: https://github.com/dheera/rosshow/raw/master/screenshot3-ascii.png?raw=true https://github.com/dheera/rosshow/raw/master/screenshot3-asc... Unfortunately this utility isn't really usable outside of the context of robotics and ROS but one could extract the map rendering functionality and create a separate utility out if it if they wished. The main difference in approach between this and Mapscii is that I actually just convert raster map tiles from OSM instead of using the vector data.
