v2 v3 9 9 == While surveying == 10 10 11 1. Start your voice recorder and obtain a fix with your GPS. 12 2. One you have a fix, you might want to start moving just to make sure your location is clear 13 3. Simulteneously add a waypoint to the GPS and add an audio cue to the sound track, for example "synchronization cue.... NOW!" 14 4. Do your surveying. Whenever you want to dictate notes, make a waypoint on your GPS just before you speak. For points of interest, be sure the waypoint will indicate its location; for street names you just need to be sure there won't be any ambiguity in the position. 11 1.

Whenever you want to dictate notes, make a waypoint on your GPS just before you speak. For points of interest, be sure the waypoint will indicate its location; for street names you just need to be sure there won't be any ambiguity in the position. 15 18 * If your GPS doesn't allocate a number to the waypoint automatically, consider giving it a name. 16 19 * Ideally, dictate the waypoint name/number before describing it: "point 32: C of E Church, St Luke's, on left set back 30m from the road" … … 23 26 24 27 3. Open your GPX file. This will create (a) a GPX layer showing the track and (b) a Marker layer containing the waypoints. 25 * if you don't see Markers, it is possible your GPS represents these by giving names/numbers to particular points on the track rather than separate waypoints. You can make Markers from these explicitly using [wiki:Help/Action/MarkersFromNamedPoints Markers From Named Points] from the context menu of the GPX layer; and automatically by turning on the 'Create markers from named trackpoints' option in[wiki:Help/Preferences/Audio Audio Preferences]. 28 * if you don't see Markers, it is possible your GPS represents these by giving names/numbers to particular points on the track rather than separate waypoints.

Re-synchronization only affects later markers, so earlier ones will not change. 47 c. you may need to re-synchronize (as per 5ff above) on a later marker (perhaps you paused while making the recording). Re-synchronization only affects later markers, so earlier ones will not change. 45 48 46 49 Back to [wiki:Help/HowTo/AudioMapping Audio Mapping]
