You can now show the following for each leg of a route:
route leg length
Magnetic compass heading
True compass heading
Each of these can be enabled/disabled individually (see the settings page). The magnetic course value is derived from the World Magnetic Model (currently WMM2020, valid from 2020-2025).
Bug fixes
MAJOR performance improvements in route editing on phones and mobile devices.
DeepZoom was designed for trips on the water. But you can also use it for
driving, hiking, and biking trips.
Here’s an example of a multi-modal trip, biking from Blaine, WA through the
San Juan Islands. Each terrestrial leg is a separate route, and each ferry ride is a separate route.
To create terrestrial routes, first define start, end, and waypoints as you normally would with
aquatic trips. Then on the routes page, change the mode of transit (driving, walking, biking),
and your route will be converted to the new mode.
If you need to change the route, the easiest way is just to convert back to the original “great circle” or
ship/plane navigation mode, add or change waypoints, and then convert back to driving, walking, or biking.
DeepZoom works worldwide for trip planning. Here’s an example of transiting the Cape Cod Canal
when the current is flowing at peak velocity.
When you save a trip in DeepZoom it resides in the cloud. You can specify whether it can be viewed by the general public
or only by persons with whom you share a link.
In either case, just copy the link and share it with anyone you want:
New Zealand is one of the few countries in the world which makes their nautical charts available for free.
Others include the USA, Brazil, and Argentina. Here’s a good listing of the worldwide nautical publishing agencies. And the USA is the only country which has placed in the public domain the tide and current
harmonics needed by DeepZoom to create animated current displays.
Instead, each country has a semi-functional website where you can license charts and download them in a bewildering array of formats.
Or you end up just paying your charting application to handle the licensing on your behalf.
Since this is a low budget operation, I can’t justify the rather exorbitant licensing cost for charts from each national government publishing entity.
If DeepZoom ever grows up to play in the big leagues, it will need to face this issue.
I started the original incarnation of DeepZoom sometime around 2008, mainly to learn web technologies and because I couldn’t find a good web visualization of tides and currents.
While sailing and kayaking in the Pacific Northwest and Alaska, I would sometimes find myself making little or no progress against a substantial tidal flow, so it’s been easy to become obsessed by the topic of tides and currents. Plus, I spent formative years of my youth with the wharf rats under the industrial docks in Everett, Washington, where tides were the main event.
The original version of DeepZoom was built with Silverlight, and then a version followed for Windows Phone. The Windows Phone version was actually kind of nice, responsive, and presenting a reasonably easy environment for me, the developer. But overall - What a fiasco!, having both technology platforms fail so spectacularly. Thanks, Microsoft!
Eventually I rebuilt everything using web technologies like Bootstrap and D3. It worked well enough and then I got distracted imaging neurons at the Allen Institute for Brain Science for a few years.
Being largely homebound for the duration of Covid-19 provided an opportunity to rework DeepZoom yet again, this time switching to Quasar/Vue as the primary client framework. And then came unbridled feature creep: trips, routes, markers, tracks, pilot charts, wikipedia, and the ability to share trip plans with others.

Where to next?
I’m often at a loss to figure out what features to prioritize next.
I’m just trying to include all of the tools I like to use when planning a voyage of a day, week, or months. If you have any suggestions,
I’d love to hear from you on the discussion forum.
Changing a route departure time by clicking the clock icon wasn’t working.
Searching for lat/lng coordinates handles more formats.
Null exception in TripFind if no firstName.
Allow marker selection except when creating or editing routes.
Copy postion or marker link to clipboard failed in Prodction.
Refreshing the PWA version when a new version is released seems happier. ☺
v 3.14.0
2024.03.14
New features
Updated NOAA charts. All NOAA chart depths are now in feet.
Updated NOAA tides and currents data to January 2024 release.
New route and marker creation and editing dialog.
New dialog to publish a private marker collection onto the public map.
Tracks are now timeline aware
Routes can be disabled. This is useful for boundary marking.
Marker star ratings are now displayed on the map.
Many improvements in editing routes and markers, both touch and mouse.
Many UI improvements throughout.
Bugs fixed
Many
v 3.1.4
2023.05.16
Bugs fixed
Sometimes tides and currents would not get updated without initially moving the chart.
A big deal! Instantaneously update time when changing route departure date/time or speed. This feature was present on many early versions of DeepZoom but was problematic because routes were sometimes autoselected in a confusing fashion. I think this is finally fixed, enjoy!
v 3.0.99
2023.05.08
Bugs fixed
the Now! button would sometimes switch the time zone display to UTC.
+/- day or week increment buttons under the tide graph were not working correctly.
Verification email confirmation was sometimes silently ignored.
v 3.0.89
2023.04.28
Bugs fixed
Never change map center when selecting a route.
Propogate route name changes onto time slider.
Update browserlist to handle 89% of all browsers.
Make changing timebase settings rational.
v 3.0.75
2023.04.01
New features
When used in iFrame, each instance of DeepZoom uses a unique localstorage.
Bugs fixed
Position marker correctly at start or end of route when using Timewarp.
fix getLayer() error at startup on some devices.
v 3.0.51
2023.03.08
New features
Added 3 day weather sample trip
Bugs fixed
Clicking “Now” in “Animation Settings” no longer changes duration to one day unless “now” is outside animation duration
loopCount value is incremented after trip is completed, but before any “post” scripts are executed.
