[9fans] Road-highlighting like in games/roads

[a]

2nd Edition Plan 9 had a neat program, games/road, which
provided a map of the US with data on roads and the like.
Among other neat features was the ability to highlight
just requested features. For example, you could have the
map show just I-80 and US-22.

I've got a project (not related to Plan 9) in which that
particular function would be very useful, but I've never
seen it in any other mapping application. Has anyone
seen such a thing elsewhere?

This is typically what a G.I.S. delivers (kerGIS can do this; but the
public version is orphaned and will need to clean up all the curses
programs---one can do without: they are just interfaces---and add a rio
displaying device; kerGIS not public... is not public...). For other
open source GIS, I guess you will have rough times since they are
monsters probably not even very POSIXly correct...
