I've been using Navionics
on my iPad
running the iNavX
app with Charts
downloaded from Fugawi
X-Traverse for about a year now and have been reasonably happy with it. Come yesterday and I downloaded the new charts I'd need for my next voyage (South Pacific) only to find that Fiji
is cut neatly in two. As I paid good money
to have these charts I was a little incensed to find this most inconvenient bug and so I wrote to X-Traverse for an explanation.
Here is their reply......
In our 34XG product description page at
... we do mention issues along these lines, just above the FAQs and below the "How do I get started?" section. We state:
SPECIAL USAGE NOTES for 34XG charts: iNavX
presents some chart regions such as Fiji
into two segments that cannot be smoothly panned through from east to west. Additionally, between 179 and 180 degrees longitude, depth
soundings may be excluded from the chart graphics. These and related issues will be addressed in the future.
What is happening, on a more technical level, is that there is an old graphics engine
vector charts that iNavX relies on, and that old engine
has some known issues & limitations like the ones you've seen so far. So the chart itself is fine, and the overall coding of iNavX is fine (ie. if there was a raster chart of Fiji for display, iNavX would show it all together as one easily panned-through image); it is only the specialized licensed graphical engine for the vector charts that has a problem around the 180 longitude line. On my X-Traverse end of things, I have no fix for this (because I merely sell the charts and help with downloading them -- and the charts themselves are actually okay when viewed in softare using the newest graphical engine on Windows computers).
The bottomline is that, for the forseeable future, you will need to continue working around the peculiarity you've encountered. I hope in the future that the newer Navionics graphics engine can be deployed in the iOS environment
and that would presumably solve the issues at hand. If this current
sitation is no good for you, I can ask our Sales Manager to refund the 34XG for iPad purchase
and I'll remove it from your account.
Not happy, but what else can I do (other than buy a Window$ machine... which I am not
going to do).
Anybody else come up against this issue?
