Hi Fred, thanks very much for the nice feedback! The "snap to road" feature is definitely a useful thing! In case of the Vidmap editor I chose to use the <shift> key to switch between snapping and straight lines. You might have a better idea to achieve the same effect? Let me know.
Regarding the intermediate waypoints, I've so far chosen the following way: -There's a small circle next to the cursor snapping to the (already existing) polyline -This circle can be dragged anywhere -When released, an intermediate waypoint is inserted in an internal array of points -The adjacent two waypoints are then connected to the new waypoint This is kind of similar to the usual behavior of the Google Maps JS directions editor, except that I found it useful for Vidmap to have the possibility to optionally add straight lines instead of a routed path. I just created a screencast for you, demonstrating the described behaviour. You can find it on the vidmap blog: http://blog.vidmap.de/2009/07/screencast-how-to-geo-tag-video.html Just tell me if you need more information. -mario On Jul 28, 3:01 pm, Fred <[email protected]> wrote: > Juguang - thanks for the feedback!
