Re: Offline maps are useless with apps that phone home

Interesting thread. Thanks to all who have contributed.

I was (and to a certain degree still am) a Navionics fan. I just hate that they reduced the area coverage in some instances.

I have downloaded the navionics charts onto my devices with the Boating App, but find that when I am offline it does not want to show the satellite images. Any ideas?

I just looked as isailor as a plan B backup. Looks interesting. When I want to purchase a chart for my area it says “1 year chart correction subscription” . If I do not renew this in 1 years time, will I lose the chart or just no longer get corrections?

Edit:
Found this on their website:
“Available Chart Folios cover coastal and offshore waters of North America, Latin and South America, Europe, Africa, Middle East, Far East, Asia, Australia & New Zealand.
All chart folios can be selected, purchased and downloaded via the Wärtsilä iSailor app using its Chart Store section. Purchased chart folios includes a one year Chart Updates subscription service of your chosen coverage. At the end of one year you can choose to renew your Chart Updates subscription service or continue to use the charts you previously purchased and downloaded.”

But, seriously, it is a shame that otherwise good hardware like the iPad is hobbled by the manufacturer this way.

And, yes, I know this discussion will descend into religious fervor over people's preferred platform. It's inevitable anyway, so I decided to join in, just this once.

Sorry.
Reasoning doesn’t matter, fact is that OpenCPN is not available for iOS while other apps are which, combined with the fact that a huge group favors Apple’s superior hardware/silicon, means OpenCPN is beat by AquaMap hands down.

ISailor isn’t supporting Android (anymore). If you have iOS then I recommend Aquamaps #1 and iSailor #2 while having both is the best.

The good thing also is that these don’t require yearly subscription fees for the charts. AquaMap seems to but you can buy a lifelong subscription which I did for the Bahamas. I still need to pay subscription for app features but that’s not bad. In iSailor you pay a one time fee for features as an in-app purchase. The chart subscription is for updates only.

I am not sure why you believe Navionics does not work offline - without the internet? Mine works fine on my tablet... I have downloaded all the maps I need prior to leaving port.



Quick search on google confirms the same...

Satellite images are downloaded on the fly… same for AquaMap. The iSailor info is correct, you keep the charts but loose the updates, which is how all should do it.

Re: Offline maps are useless with apps that phone home

even when offline apps and electronic charts are just as useful as charts, probably even more as you don't have to flip pages and can zoom in/out easy

It works fine for a while depending on who knows what. At some point it will insist on phoning home for authorization and will not work until it is able to do so. I don't know what triggers it -- reboots, passage of time, presence or absence of an internet connection, who knows. I have had it happen to me more than once. Maybe Navionics has changed the app but I don't trust it any more.



If I'm out in the middle of nowhere trying follow my track back after picking my way into some shallows, I can't have the app locking out on me. It's totally unacceptable for any piece of navigational software. No navigational software should ever deliberately shut down or disable features.

Re: Offline maps are useless with apps that phone home

Navionics Boating App…

I found this over here…
https://support.garmin.com/en-ZA/?fa...GPS%20receiver)
Navionics Boating App Features, Online vs Offline

“There are several features within your Navionics® Boating app that require an active internet (Cellular or Wi-Fi) connection.

Chart downloads and updates (GOVT charts, Nautical Chart, SonarChart™)
Downloadable map overlays (Relief Shading, Satellite Imagery, Sonar Imagery)
Sync My Data (to connect to your account on our server)1
Upload sonar logs (with Raymarine Plotter Sync)
Map overlay (Bing Satellite or Terrain)
Weather data (excluding tide and current data, which is part of downloaded charts)
Sharing saved items (tracks/routes/markers)
Sharing live location with Connections


When offline (no Wi-Fi or Cellular coverage) you will be able to access the following:

Previously downloaded chart detail (GOVT, Navionics Nautical Chart and SonarChart)
Previously downloaded map overlays (Relief Shading, Satellite Imagery, Sonar Imagery)
GPS position1 (if your device has an internal GPS receiver)
Save tracks, markers, routes, photos and videos1
SonarChart Live1 ( view compatibility information)
Plotter Sync (route and marker sync and chart updates)
1 Free features. All other features require an active subscription.”

However I cannot seem to get sat imagery when offline. Otherwise it works fine. It has never asked me to validate something or stopped working, but then again I am not offline for long periods, week at most. I have had it freeze on my device a few times when opening the app(ipad and iphone) but that has not happened in awhile.

Re: Offline maps are useless with apps that phone home

For OpenCPN (and the o-charts, S-63 or other chart plug-ins and sat imagery in mbTiles format) there is the design decision that offline install of charts will always work, charts will not disappear after some period and no "calling home".

We have been in contact with chart sources who insisted in subscription models and vanishing charts once the subscription ended, and always declined to enter in such type of simply dangerous implementations.
