Mom allows waypoints to be added very easily to the tracklog with descriptive text and/or voice notes and/or photos for logging the type of path, street names, etc. This functionality could be further developed. My worry is with the second part of the process - converting this collected GPX data into ways. I can imagine all sorts of problems trying to automate what is not a difficult task for someone familiar with Potlatch or JOSM but could need a great deal of programming skill. </div><div><br></div><div>elvin ibbotson</div><br></body></html>
