I actually don't want to advocate a specific map software right now, as we are likely to switch between multiple systems until we find one we like. OpenStreetMaps ( https://www.openstreetmap.org https://www.openstreetmap.org ) is the data source for most other mapping systems though. Suffice to say, I am setting it up so that it can be more easily replaced if need be.
