but also, it's interactive and we can change things on the fly, we can highlight things, we can take things out, we can add things in. so, it's much more responsive and adaptable compared to when you're just updating stuff like paper maps. can you show me how it all works? yeah, of course. you go to the map of where you are, you find the path that you want. you just tap on the path and then tap on "open survey". and then that takes you through to the questionnaire. and then we just tell volunteers that they can fill in as much or as little as possible. much of the questions are not mandatory, so if the volunteers aren't sure about something, they can skip it, because we don't want to put them off, saying, "i don't know that question, "so i'm not going to do it at all." volunteers have so far added over 9,000 new paths to the interactive map, from as far north as the shetland islands to the borders region in the south. i think the project's really important for our paths in scotland. it's a chance to support and to maintain that right to roam, but it also makes these paths more accessible to a wider variety of people.
