Frankly at this point I am at a loss. Using the HowDoISampl -ForiOS I modified the UseOpenSteetMapOverlay file so that the extents are set as follows
new RectangleShape(-10914959.8856762, 3577180.44738464, -10838593.5553671, 3534701.67615024);
This should position the map in the Austin Texas area, but instead positions the map North of Alaska.
This matches the same behavior we are seeing in our application. In our Android and WPF versions these coordinates do in fact show the Austin area. Unfortunately I tried duplicating this in HowDoISample-ForAndroid, and ended up with the same results as HowDoISame for iOS with the map displaying the same area north of Alaska. I am at a los here -- I basically modified our code and created a single layer exactly as done in the Android HowDoI bypassing all of our initialization code and the coordinates provided showed the Austin area as it should. I am fairly certain that I did not overlook any of our initialization code that might affect this.
We are using Xamarin forms for this with Visual Studio 2015 -- Samples and Our code were all built with the latest beta daily builds from nu-get..
I am hoping you can reproduce this as I cannot for the life of me figure out why the wrong area is beings shown.
