Using GPS coordinate pairs to find the next polygon in a specific direction

[Andy B.]

Hi,

 

I am trying to create a "look around" feature in Talking flight monitor. The feature allows a pilot to choose a specific heading, 128 for example. Once that is done, the pilot would then have a choice on what to receive. Distance to the next polygon (geographical area) and its name, or a list of all polygons and their names in the current direction (128 in this example). Other features might come later, but it depends on whether I can get the basic framework working. What I can do so far, is get a polygon from Bing maps. Beyond this, I am stuck. Does anyone have any ideas on how to move forward with this feature?

Hi Andy,

This sounds a lot like the work I did for you and Jason at the end of 2020.

I'm pretty sure the FsLatLonPolygon can be used to do what you described.
