I'm not sure if this is the right place, as there's not any discussion yet - but first, I love DeepZoom! My question - I would love to know if there's a plan to use the current information in combination with the Routes/Trip to predict travel time (including currents)? I love DeepZoom, and I see that it now has the route/trip feature (AMAZING) and displays the predicted current arrows onscreen for a given trip (even far into the future). However, if I change start time by grabbing the slider, I don't see my overall route duration changinglike I would expect (Longer if my departure time means I'm fighting a tide, shorter if I get a boost). Sorry for all the words, but is that feature already there and I'm missing it? It would be super helpful to plan a leg of a trip (day to day) and drag the start slider to see how it changes my total travel time that day....

No you're not missing this feature, and I'd love to be able to implement it, but it's just not feasible at present. Currents are only measured at a few fixed locations. Trying to extrapolate from these known points across a large area would be fraught with errors since hydrodynamics are complex and non-linear. So I shift the burden onto you to estimate your speed given the displayed current velocities.

There are models which have been developed for specific areas such as this one for the Salish Sea:
but I'm not aware of larger scale models which could be used.

Hi. I've barely started fiddling with DeepZoom since someone showed it to me this week. Maybe it is a way to share kayaking trip reports with wind and current detail. Through the web interface I can upload new trip *.gpx recorded on any device. When I click on the Time readout / Calendar button at the bottom, I cannot adjust the start of an animation to anything more precise than one day. Same with the Timebase duration drop down on the big right hand 'Trips' tab ( where also the trip length and duration do not auto fill and can't be set manually ) Can't it autodetect when a *.gpx starts and stops? I have to manually select the start day, and manually find the start time of the trip on the 24 hour slider . But I've just tarted trying so maybe I'm missing things. Google browser on Linux.

Try this:

1. Import the .gpx file. At present, DeepZoom just retains the points as a track and ignores the timestamps. No good reason for this omission, I just haven't done the work yet! But for the moment...
2. Go to the Track page and select the track. Click the Track -> route button..

3. Now you can manipulate the speed, and starting time of the route.

The next version may include an option dialog when importing a .gpx automatically doing step 2 on all imported tracks.
