Wrapped MapItems

May 11, 2015 at 8:31 PM
Is there a way to draw say, a MapPolyLine so that it doesn't get cut off at the map boundries, and instead wraps around to the other side?

Not sure what you mean exactly, as you haven't provided an example. But a MapPolyline won't wrap out of the box, at least not partially.

I have the same problem over here. Im not able to draw a line crossing the pacific (eg. Tokyo to San Francisco) - it always takes the way over Asia.
Intersecting the line at longitude -180/180 doesn't really help, since it leads to two fragments on the map, always covering the -180 to +180 longitudal range...

An hints to get a line over this boundary?

If you have locations in a polyline east of 180° or west of -180°, just use longitude values >180 or <180, respectively.

Sounds intuitive... ;)
...and works very well. Thank you for the quick reply!

A related problem:

Could it be, that pushpins are only displayed at one location, even if they created on earth-multiples of the longitudes?
I have a track from 'Tokyo' crossing the pacific to 'San Francisco', 'New York', 'Berlin' and forwarding to 'Tokyo' again, but only one 'Tokyo' pushpin is shown?!?

One pushpin is obviously displayed at exactly one location. Otherwise there would have to be some magic that replicates child elements of a MapPanel. The actual viewport position is calculated so that it is nearest to the center longitude of the current map viewport.

Unfortunately this logic doesn't match very well to lines crossing the pacific. The track and the pins are often an earth rotation apart.
Any hints before I try to tweak your component?
(BTW: Thanks again for your outstanding support and efforts!)

Sorry, no. In case you're "tweaking" anything, please do not send a pull request. It will be rejected.

@Irgendwer, I have removed your post because the code would break basic behaviour of the Map Control. Please stop this discussion.
