It's very easy of use; it can be used in several ways (street view); there are many options for customization/filtering available online or offline ; you have an interface with other modules from third parties such as Google Earth Pro : so that is also something I like! Nothing specific at this time but do not hesitate when purchasing because they could come out new releases which will improve your workflow :) The first module we purchased was Street View mapping - we were able search streets by their ID number etc.; then later came map matching between our database & theirs! This allows us to know what roads belong to whom without having trouble finding them using maps alone ;).
