[HOT] newbie needs advice - connecting paths

Walking in Nepal one can be on a path and it will suddenly disappear, and then you walk across open ground to your destination. People don't necessarily walk on a path, especially between houses, and houses in the same "village" can be a quarter mile away or more. Knowing this, I have not connected paths blindly. I know they just end sometimes. Yet it is still valuable to know where they are.
Most of the Bing imagery I'm working with was taken during the dry season, so all the rushing great streams and rivers are dry. In the wet season they will be roaring with water. Good to map them.

I was also wondering about the best approach to connecting paths.
On one hand all highways only make sense when they are connected, on the other it does not feel good to me to guess too freely where an invisible path might go. Particularly in steep terrain paths that are quite close horizontally really don't connect, as there can be a cliff or something in between. I often feel tempted to close a short gap "blindly" but did not as this can be really dangerous. It's probably better to leave it as patchwork and hope that the map will be improved later with better imagery or people with local knowledge.
In other situations it feels quite safe to fill in the blanks, like when a clearly visible road disappears into a small forest and the same type of road appears on the other side.
As to waterways and paths it often helps to follow them for a longer stretch and see where they go. This often gives you a better picture, if you see them run into a bigger river for example.
PS I'd also prefer a more permanent place than IRC to get answers, so people can read them up later. Maybe a kind of forum would be useful to not clog up the mailing list?

Betreff: [HOT] newbie needs advice
I am a newbie coming up with a few questions, It would be great if someone with more knowledge could take the time to answer them. They don´t have to be answered here and now or via mailinglist, I am also on IRC #hot as katjaulbert. I am mapping in task #1018.
1) Paths: I have come across some that are obviously connected but there are small areas where I cant´t follow their course. Same with paths that lead into forests, where they disappear and reappear on the other side. Should I connect them? I don´t think it´s useful to have tiny bits of paths in the map or paths that lead into nowhere.
2) I need advice to distinguish dried waterways from paths. Waterways seem to be much broader and uneven and often accompanied from paths.
3) Tags: I cant´t find some tags that are advised in the task instruction, for example bridge=supension. Are there any presets I forgot to load?
4) Imagery: I use Bing and Mapbox, are there any more sources? Also, is there a way to digitally zoom Mapbox imagery? Sometimes it´s easier to spot things with Mapbox, especially paths, but it stops displaying at some point.
Thanks for taking time!
